Introduction

The Laird DVK-BL652 development kit provides a platform for rapid wireless connectivity prototyping, providing multiple options for the development of Bluetooth Low Energy (BLE) plus Near Field Communication (NFC) applications. The Laird BLE development kit is designed to support the rapid development of applications and software for the BL652 series of BLE modules featuring Laird’s innovative event driven programming language – smartBASIC. The BL652 development board is a universal development tool that highlights the capabilities of the BL652 module. The development kit is supplied in a default configuration which should be suitable for multiple experimentation options. It also offers a number of header connectors that help isolate on-board sensors and UART from the BL652 module to create different configurations. This allows you to test different operating scenarios. The development board also has support for plugging in 3rd party Arduino Shield boards. The development board allows the BL652 series module to physically connect to a PC via the supplied USB cable for development purposes. The development board provides USB-to-Virtual COM port conversion through a FTDI chip – part number FT232R.

Features

• BL652 series module soldered onto the development board
• The following power supply options for powering the development board:
  • USB (micro-USB, type B)
  • External DC supply (7-12V)
  • AAA batteries (three AAA battery holder fitted on underside of development board)
• Regulated 3.3V for powering the BL652 module. Optional regulated 1.8V for powering the BL652 module via selection switch
• Power supply option for coin-cell (CR2032) operation of the BL652 module ONLY (not development board)
• USB to UART bridge (FTDI chip)
• BL652 UART can be interfaced to:
  • USB (PC) using the USB-UART bridge (FTDI chip)
  • External UART source (using IO break-out connectors J1 when the development board is powered from a DC jack or AAA batteries)
  • Arduino connector by use of an analog switch to route the BL652 UART
• Current measuring options (BL652 module only):
  • Pin header (Ammeter)
  • Current shunt monitor IC (volt meter or oscilloscope)
  • Series resistor for differential measurement (oscilloscope)
