About this item

The SparkFun Pro nRF52840 Mini is a compact development board featuring Nordic Semiconductor’s powerful nRF52840 chip, which combines an ARM Cortex-M4 CPU with a 2.4GHz Bluetooth radio. It offers native USB support for programming, powering, and communication, enabling versatile use with UART, I2C, and SPI interfaces—similar to the Arduino Pro Mini. The board integrates the Raytac MDBT50Q-P1M module, which connects the chip to a trace antenna, provides an FCC-approved footprint, and includes essential decoupling and timing components. This makes it a convenient and efficient platform for Bluetooth and embedded applications.
