## **1.0 DEVICE OVERVIEW** 

The RN2483 transceiver module features LoRa Technology RF modulation, which provides long range spread spectrum communication with high interference immunity. 

Using LoRa Technology modulation technique, RN2483 can achieve a receiver sensitivity of -146 dBm. The high sensitivity combined with the integrated +14 dBm power amplifier yields industry leading link budget, which makes it optimal for applications requiring extended range and robustness. 

LoRa Technology modulation also provides significant advantages in both blocking and selectivity compared to the conventional modulation techniques, solving the traditional design compromise between extended range, interference immunity, and low-power consumption. 

The RN2483 module delivers exceptional phase noise, selectivity, receiver linearity, and IIP3 for significantly lower power consumption. Figure 1-1, Figure 1-2, and Figure 1-3 show the top view, the pinout, and the block diagram of the module.

## **3.1 Interface to Host MCU** 

The RN2483 module has a dedicated UART interface to communicate with a host controller. Optional handshake lines are supported in future firmware releases. The _“RN2483 LoRa[®] Technology Module Command Reference User’s Guide”_ (DS40001784) provides a detailed UART command description. Table 3-1 shows the default settings for the UART communication. 

## **TABLE 3-1: DEFAULT UART SETTINGS** 

|**Specification**|**Description**|
|---|---|
|Baud Rate|57600 bps|
|Packet Length|8 bit|
|ParityBit|No|
|StopBits|1 bit|
|Hardware Flow Control|No|



## **3.2 GPIO Pins (GPIO0-GPIO13)** 

The module has 14 GPIO pins. These lines can be connected to switches, LEDs, and relay outputs. The pins can be either logic inputs or outputs, and some pins (see Table 1-1) have analog input capability that can be accessed via the module firmware. These pins have limited sink and source capabilities. Electrical characteristics are described in Table 2-2. For more information, see _“RN2483 LoRa[®] Technology Module Command Reference User’s Guide”_ (DS40001784). 

## **3.3 RF Connections (RFL, RFH)** 

RFL is the RF analog port for the lower frequency band (433 MHz) while RFH is for the higher frequency band (868 MHz). When routing RF paths, use proper strip lines with an impedance of 50 Ohm. 

DS50002346C-page 9 

 2015-2017 Microchip Technology Inc. 

## **RN2483** 

## **3.4 RESET Pin** 

The RESET pin of the module is an active-low logic input. An internal weak pull-up resistor is enabled when the pin is configured as the MCLR input. 

## **3.5 Power Pins** 

It is recommended to connect power pins (Pin 12 and 34) to a stable supply voltage with sufficient source current. Table 2-3 shows the current consumption. 

Additional filtering capacitors are not required but used to ensure stable supply voltage in a noisy environment. 

## **3.6 Internal Program Pins** 

PGC_INT (Pin 30) and PGD_INT (Pin 31) are internal program pins used during manufacturing. For normal operation, these pins can be left unconnected. 

The normal firmware upgrade method is through the internal bootloader of the module via the UART. The method is documented in the _“RN2483 LoRa[®] Technology Module Command Reference User’s Guide”_ (DS40001784) _._ 

However, for backup firmware update purposes the user can place a 6-pin ICSP header on their host PCB with PGC_INT (Pin 30), PGD_INT (Pin 31), RESET (Pin 32), power and ground. 

During High Voltage In-Circuit Serial Programming mode, the RESET pin is driven with high-voltage (9V), therefore protection may be necessary for sensitive devices. 

**Note:** Only official Microchip Technology firmware released for the RN2483 module shall be used to maintain FCC and IC certification.

## **6.0 REGULATORY APPROVAL** 

This section outlines the regulatory information for the RN2483 module for Europe. 

## **6.1 Europe** 

The RN2483 module is an R&TTE Directive assessed radio module that is CE marked and has been manufactured and tested with the intention of being integrated into a final product. 

The RN2483 module has been tested to R&TTE Directive 1999/5/EC Essential Requirements for Health and Safety (Article 3.1a), Electromagnetic Compatibility (EMC) (Article 3.1b), and Radio (Article 3.2) and are summarized in Table 6-1: European Compliance Testing. A Notified Body Opinion has also been issued. All test reports are available on the product web page at http://www.microchip.com. 

The R&TTE Compliance Association provides guidance on modular devices in document **Technical Guidance Note 01** available at http://www.rtteca.com/html/download_area.htm. 

**Note:** To maintain conformance to the testing listed in Table 6-1: European Compliance Testing, the module shall be installed in accordance with the installation instructions in this data sheet and shall not be modified. When integrating a radio module into a completed product the integrator becomes the manufacturer of the final product and is therefore responsible for demonstrating compliance of the final product with the essential requirements of the R&TTE Directive. 

## 6.1.2 EXTERNAL ANTENNA REQUIREMENTS 

From R&TTE Compliance Association document **Technical Guidance Note 01** : 

Provided the integrator installing an assessed radio module with an integral or specific antenna and installed in conformance with the radio module manufacturer's installation instructions requires no further evaluation under Article 3.2 of the R&TTE Directive and does not require further involvement of an R&TTE Directive Notified Body for the final product (Section 2.2.4).

## **Note the following details of the code protection feature on Microchip devices:** 

- 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.” 

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act. 

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application meets with your specifications.

Use of Microchip devices in life support and/or safety applications is entirely at the buyer’s risk, and the buyer agrees to defend, indemnify and hold harmless Microchip from any and all damages, claims, suits, or expenses resulting from such use. No licenses are conveyed, implicitly or otherwise, under any Microchip intellectual property rights unless otherwise stated. 

_Microchip received ISO/TS-16949:2009 certification for its worldwide headquarters, design and wafer fabrication facilities in Chandler and Tempe, Arizona; Gresham, Oregon and design centers in California and India.
