The SparkFun Pro nRF52840 Mini is a breakout and development board for Nordic Semiconductor’s nRF52840 – a powerful combination of ARM Cortex-M4 CPU and 2.4GHz Bluetooth radio, allowing development of Bluetooth 5, Bluetooth Mesh, Thread, IEEE 802.15.4, ANT and 2.4GHz proprietary wireless applications.
This mini development board for the nRF52840 breaks out most of the critical I/O pins including GPIO and those needed for power while maintaining a small footprint that nearly matches that of the Arduino Pro Mini. It features a USB interface (using the nRF52840’s native USB support), which can be used to program, power, and communicate with the chip making it able to be used for any purpose (UART, I2C, SPI) that those of the Arduino Pro Mini could.
The Pro nRF52840 Mini features a Raytac MDBT50Q-P1M module. This module connects the nRF52840 to a trace antenna and fits the IC into an CE-approved footprint. Also included onboard is a LiPo battery charger, a Qwiic connector, an on/off switch, a reset switch, and a user LED/button.
The board comes pre-programmed with a USB bootloader. You can develop programs for the nRF52840’s Cortex-M4 using either Arduino, Circuit Python, or C (using Nordic’s nRF5 SDK), and load that compiled code using a USB serial or mass-storage interface.
