The acnDEV is a free configurable BLE beacon that serves as a development platform. It is based on aconno’s ACN52832 Bluetooth 5 module and designed to deliver sufficient processing power with ultra-low power usage and long battery life. The module can be programmed through a Tag-Connect connector with the ARM standard SWD interface. But we recommend the use of our specially designed, easy to use USB-Programmer ACNProg. For coding examples, look for us (team dev aconno) at mbed.org To speed up the development of SMD-circuits, the DEV Beacon offers a 20 x 16 mm board area with solder pads in a 0.8mm pitch. This allows the board to universally accommodating simple surface mounted devices. Each beacon comes with a circuit pen and a premium battery and packed in a solid, highly durable casing. Solder components on the board, connect with conductive pen and configure analog/digital pins by Sensorics app without writing a single line of code.
