The MakerBLE board is a Bluetooth Low Energy (BLE) microcontroller development board based on Nordic’s nRF52840 chip. The MakerBLE acts as an Arduino board and a BLE-enabled device. It has much of the functionality of classic Arduino boards, while also having an integrated BLE chip capable of communicating via BLE 5.0. This means that many Arduino projects can be Bluetooth-enabled with just a few lines of code and the BLExAR app!
