Development Board
Blip - Electronut Labs
Blip is a development board for Bluetooth Low Energy (BLE) and 802.15.4 based wireless applications, based on the Nordic Semiconductor nRF52840 SoC. It has a Black Magic Probe compatible programmer and debugger built-in along with temperature/humidity sensor, ambient light intensity sensor, and a 3-axis accelerometer. It is usable to prototype for very low power applications, and debugger and regulator can be disconnected when only SoC needs to be powered.
