SparkFun Pro nRF52840 Mini - Bluetooth Development Board

Regular price $0.00 $41.66 Sale

Key Features:

  • Breakout and development board for Nordic Semiconductor’s nRF52840
  • Peripheral-multiplexing
  • Every I/O peripheral you could need
  • Integrated 2.4GHz radio with support for Bluetooth Low Energy (BLE), Bluetooth 5, ANT, Nordic's proprietary RF protocol

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.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 (except those covered by the Qwiic Connector). 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, fits the IC into an FCC-approved footprint, and also includes a lot of the decoupling and timing mechanisms that would otherwise be required for a bare nRF52840 design. Also included onboard is a LiPo battery charger, a Qwiic connector, an on/off switch, a reset switch, and a user LED/button.
