BL620-SC

## BL620 Series 

## **Central Mode BLE Module Featuring smartBASIC** 

The BL600 Series modules from Laird have been enhanced with the addition of the BL620 part numbers. The BL620 uses the same module hardware as the BL600 but has a new SMART firmware supporting Central mode connectivity. The BL620 makes it easy to add single-mode Bluetooth Low Energy (BLE), also known as Bluetooth Smart™, to small, portable, power-conscious devices, €} Bluetooth including those powered by AAA or coin cell batteries. 

The unique feature of this module is smartBASIC, an event-driven programming language that enables standalone operation of the module. smartBASIC on BL620 enables wireless connections to peripheral devices that are in turn connected to sensors so that the data can be collected via GATT operations. smartBASIC has been proven to speed time to market and significantly simplifies BLE integration for embedded devices. 

Based on the award winning Nordic Semiconductor nRF51822 chipset, BL620 modules provide exceptionally low power consumption with outstanding wireless range, all within a compact footprint of 19 mm x 12.5 mm. The modules incorporate all the hardware and firmware required to support development of BLE Central mode applications, including: 

- Radio hardware 

- UART, SPI, I2C, ADC, and GPIO interfaces for connecting peripherals and sensors 

- A complete BLE software stack 

- Central role functionality with GATT client and server 

   - Ability to connect up to four simultaneous connections 

- Custom Services to suit any application’s needs 

- Series addition of a packaged USB Dongle  - BL620-US

The BL620-US USB Dongle has been developed to take advantage of the BL620 module, providing the ability to add BLE Central Mode capabilities to Windows operating systems supporting a USB interface and virtual COM port. The control and configuration is via a standard virtual COM port and smartBASIC. The dongle provides the ability to load smartBASIC applications over the air (OTA) to a BL600 peripheral mode module. 

In addition to carrying FCC modular, IC, and CE approvals, BL620 modules are fully qualified as a Bluetooth End Products, enabling designers to integrate the modules in devices without the need for further Bluetooth Qualification testing. 

Customers can use the DVK-BL600 series low-cost developer’s kit including simple software tools to develop with the BL620 central mode firmware.
