Pro nRF52840 Mini - Bluetooth Development Board

Description

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. With the nRF52840 at the heart of your project, you’ll be presented with a seemingly endless list of project-possibilities in an incredibly small package. Our 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, I 2 C, 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. 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.
