nrf52840-mdk board corresponds to the
Makerdiary nRF52840-MDK board. It
runs on an nRF52840 ARM CortexM4 microcontroller from Nordic with BLE and
802.15.4 radio support.
nrf52840-mdk board can reset, debug and program the ARM Cortex M4
through the embedded debugger (DapLink) connected to the gateway USB port. This
component also allows a UART connection to the M4.
IoT-LAB special configuration
The serial connection baudrate should be configured at 115200 bauds in the firmware and use UART0/UARTE0 on pin 19 (RX) and 20 (TX).
Schematics and Datasheets
The hardware configuration is available here.
The board is running on an nrf52840 microcontroller.
