Description

Miniature module with a microcontroller, equipped with the ARM Cortex M4 64 MHz core, 256 kB of RAM, 1 MB of Flash memory. It has a built-in nRF52840 module equipped with Raytac MDBT50Q-P1M supporting Mesh and Bluetooth 2.4 GHz, and 20 GPIO pins, working with voltage of 3.3 V. In addition, the module has a Qwiic connector to connect sensors. Board has a system for charging rechargeable Li-Pol batteries, on/off switch, reset button, LED and button at the user disposal.

Communication

Thanks to the installed nRF52840 module, the user can, in a simple way, communicate with the Mesh network and via Bluetooth. The system is compatible with standard Bluetooth 5.

 

Pins of the module work with the voltage of 3.3 V.

Pins

On the board are interfaces such as UART, I2C, SPI. Board has combined masses on external pins of the board. The board has holes for soldering the goldpin connector with raster of 2.54 mm, which allows you to attach it directly to the breadboard.

 

Detailed description of the pins are in the user manual of the manufacturer.
