## **1.2 Module Configuration** 

The GPIO pins of the RN4870 and RN4871 modules can be configured to different functions using the ASCII command interface. Table 1-3 shows the various pins in the RN4870/71 module that are available for configuration and their default configuration settings. Table 1-4 provides details on each functions available. 

Table 1-5 shows the status of the module as indicated by the Status 1 and Status 2 indication pins. Table 1-6 shows the details of test pads that are present on the bottom side of the module, used for diagnostic purposes during testing. Figure 1-5 shows all the key elements of the module. 

**TABLE 1-3: CONFIGURABLE PINS AND DEFAULT FUNCTIONS IN THE RN4870 AND RN4871**

## **TABLE 1-4: CONFIGURABLE FUNCTIONS AND DESCRIPTIONS** 

|**Function Name**|**Description**|
|---|---|
|Low Battery Indication|Pin output goes low when the VDDis below a specified level. To set the<br>threshold level, change the EEPROM settings.|
|Status 1|Use this indication pin along with the Status 2 pin to indicate the current status of<br>the module. Refer toTable 1-5for details of the status indication.|
|Status 2|Use this indication pin along with the Status 1 pin to indicate the current status of<br>the module. Refer toTable 1-5for details of the status indication.|
|RSSI Indication|Use this indication pin to indicate the quality of the link based on the RSSI level.<br>If the RSSI level is lower than the specified threshold value, then the RSSI<br>indicationpingoes low. Set the threshold for the RSSI linkqualityin EEPROM.|
|Link Drop|When the RN4870/71 is connected to a remote device, the host MCU can use<br>the Link Drop pin to force the module to disconnect the link and and enter<br>shutdown state. Thepin needs to bepulled low for at least 10 ms.|
|UART RX Indication|Use this pin to enable communication with the UART when the module is in Low-<br>Power mode. When_not_in Low-Power mode, the module runs on a 16 MHz<br>clock. If Low-Power mode is enabled on the module by using commandSO,1,<br>the module runs on a 32 kHz clock thus reducing power consumption. However,<br>in Low-Power mode, the host MCU_cannot_communicate with the module via the<br>UART since the UART is_not_operational. If the user intends to provide data or<br>commands via UART in the Low-Power mode, then the UART RX INDICATION<br>pin must be pulled low and the user needs to wait for at least five milliseconds<br>before sending the data. Pulling the UART RX INDICATION pin low allows the<br>module to operate the 16 MHz clock and to enable UART.|

## **4.0 PHYSICAL DIMENSIONS AND ATTRIBUTES** 

## **4.1 RN4870 Module** 

Figure 4-1 shows the physical dimensions of the RN4870 module. Figure 4-2 illustrates the recommended PCB layout, and Figure 4-3 shows the recommended mounting details. 

Ensure that there is _no_ top copper layer near the test pin area, indicated by the shaded _keep out areas_ , as shown in Figure 4-2. When laying out the host PCB, the 

areas under the antenna must _not_ contain any top, inner layer, or bottom copper as shown in Figure 4-3. A low-impedance ground plane ensures the best radio performance (best range; lowest noise). Figure 4-3 also shows a minimum ground plane area to the left and right side of the module for best antenna performance. The ground plane can be extended beyond the minimum recommended as required for host PCB EMC noise reduction. For best range performance, keep all external metal at least 30 mm away from the ceramic chip antenna.

## **4.4 RN4871U Module** 

Figure 4-10 shows the physical dimensions of the RN4871U module. Figure 4-11 illustrates the recommended PCB layout. It is highly recommended to layout the host PCB as suggested in Figure 4-12. Figure 4-13 shows the recommended placement for the module on the host PCB board. For optimal transmission and reception sensitivity, place the module at the edge of the board. 

A low-impedance ground plane ensures the best radio performance (best range; lowest noise). Pin 1 (BT_RF) is a 50 ohm connection that can be connected to an external antenna such as a PCB trace antenna, a component (chip) antenna, or through a host PCB 50 ohm microstrip trace. This trace can be extended to include passive parts for antenna attenuation padding, impedance matching, or to provide test posts. It is recommended that the microstrip trace to be as short as possible for minimum loss and best impedance matching. If the microstrip trace is longer, a 50 ohm impedance is recommended.

## **4.5 Soldering Recommendations** 

The RN4870/71 Bluetooth modules are assembled using standard lead-free reflow profile IPC/JEDEC J-STD-020. 

The module can be soldered to the host PCB using standard leaded and lead-free solder reflow profiles. 

To avoid damaging the module, the following recommendations are given: 

- Microchip Technology Application Note, _“AN233 Solder Reflow Recommendation”_ (DS00233) provides solder reflow recommendations 

- Do _not_ exceed peak temperature (TP) of 250°C 

- Refer to the solder paste data sheet for specific reflow profile recommendations 

- Use no-clean flux solder paste 

- Do _not_ wash as moisture can be trapped under the shield 

- Use only one flow. If the PCB requires multiple flows, apply the module on the final flow.

## **5.0 APPLICATION REFERENCE CIRCUITS** 

## **5.1 External Configuration and Programming** 

The RN4870/71 modules can be configured and firmware programmed using an external configuration and programming tool. Figure 5-1 shows the mandatory connections required between the module and the external programming header. It is recommended to include these pin connections on the host PCB for development. For accessing the various configuration and indication pins, use Table 1-2, Table 1-3, Table 1-4 and Table 1-5. 

## **5.2 Reference Circuit** 

Figure 5-2 through Figure 5-5 show the reference circuits for various modules under the RN4870/71 family. In the circuits, the power input range is 1.9V ~ 3.6V. A battery reverse protection circuit is recommended in case a battery power input is used. Note that the VDD_IO is the same as the power input. In case of a LED connection, the power input must be greater than 3.0V. For the RN4870U, an RF antenna matching circuit must also be included as shown in Figure 5-3.

## **5.3 Power Drop Protection** 

To prevent any problems that may arise when the power supply goes below 1.9V, a power-supply dropprotection circuit is recommended. Essentially, this circuit consists of a Reset IC which acts as an _Open_ 

_Drain_ with a Delay =< 10 ms, and is triggered at 1.8V power supply. Figure 5-6 shows a recommended power drop protection circuit.

## **7.0 SUPPORTED SERVICES** 

The RN4870 supports four built-in GATT services: 

- Device Information public service 

- Airpatch private service, which handles Over The Air (OTA) updates 

- BeaconThings, which handles beacon services control 

- UART Transparent private service, which handles data streaming function 

In addition to the above predefined private services, the RN4870 provides the ability to create private services. If the services are supported on both end points of a Bluetooth Low Energy connection, such as Central and Peripheral devices, data can be exchanged. For example, two RN4870 modules can define a custom (private) service with its own unique characteristics. Data can be exchanged easily via Command API. Private services are _not_ registered with the Bluetooth SIG, and therefore _not_ interoperable with other Bluetooth Low Energy devices, unless the device implements the private service. An example of a builtin private service is the Transparent UART. For an example on how to create a custom service using the RN4870, refer to _“RN4870/71 Bluetooth[®] Low Energy Module User's Guide”_ (DS50002466). 

RN4870 allows custom defined services up to five public and four private services. Each custom defined service allows up to eight custom defined characteristics. All service definitions are saved in on-board Non-Volatile Memory (NVM) where the user must setup the module only once.

The RN4870/71 module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C “Intentional Radiators” singlemodular approval in accordance with Part 15.212 Modular Transmitter approval. Single-modular transmitter approval is defined as a complete RF transmission sub-assembly, designed to be incorporated into another device, that must demonstrate compliance with FCC rules and policies independent of any host. A transmitter with a modular grant can be installed in different end-use products (referred to as a host, host product, or host device) by the grantee or other equipment manufacturer, then the host product may not require additional testing or equipment authorization for the transmitter function provided by that specific module or limited module device. 

A host product itself is required to comply with all other applicable FCC equipment authorization regulations, requirements, and equipment functions that are not associated with the transmitter module portion. For example, compliance must be demonstrated: to regulations for other transmitter components within a host product; to requirements for unintentional radiators (Part 15 Subpart B), such as digital devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the non-transmitter functions on the transmitter module (i.e., Verification or Declaration of Conformity) as appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions).

- Microchip products meet the specification contained in their particular Microchip Data Sheet. 

- Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. 

- There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. 

- Microchip is willing to work with the customer who is concerned about the integrity of their code. 

- Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”
