Adafruit Feather nRF52840 Express BLE Development Board

Description

The Adafruit Feather nRF52840 Express is a feature-packed development board built around Nordic Semiconductor Semiconductor’s powerful nRF52840 system-on-chip. It combines a 64 MHz ARM Cortex-M4F processor with 1 MB of flash and 256 KB of SRAM, providing ample resources for complex BLE applications. The board’s native USB stack and UF2 bootloader enable seamless drag-and-drop firmware deployment, supporting both Arduino IDE and CircuitPython development environments.

Designed for portable and low-power IoT deployments, the board includes a built-in LiPo battery charger and a power enable pin for deep sleep management. Its Feather form factor ensures compatibility with the extensive Adafruit FeatherWing ecosystem, allowing for rapid prototyping with add-on boards for GPS, displays, sensors, and more. The integrated SWD connector provides direct access for advanced debugging and programming.
