Adafruit Feather nRF52 Pro with myNewt Bootloader
The Feather nRF52 Pro is an advanced Bluetooth Low Energy development board built around the Nordic nRF52832, designed specifically for use with the Apache Mynewt RTOS. It features a fully open-source BLE 5.0 stack, a serial bootloader for command-line firmware flashing, and an on-board SWD debug connector for professional development workflows.
Apache Mynewt provides professionally written networking stacks (BLE 5.0, OIC/OCF), a secure bootloader with cryptographic firmware signing, and comprehensive project management tools — all under the permissive Apache licence. The board supports UART-based BLE data transfer and custom GATT services.
Key Features
- nRF52832 Processor – ARM Cortex M4F at 64 MHz with hardware floating point acceleration
- 512 KB Flash + 64 KB SRAM – Twice the memory of nRF51-based modules
- Bluetooth Low Energy 5.0 – Fully open-source BLE stack via Apache Mynewt
- FCC / IC / TELEC Certified – Pre-certified wireless module
- Apache Mynewt RTOS – Professional RTOS with secure bootloader, OTA updates, and cryptographic firmware signing
- Mynewt Serial Bootloader – Flash firmware via USB Serial using the newtmgr command-line tool
- SWD Debug Connector – On-board connector for Segger J-Link or CMSIS-DAP debugging
- DFU Button – Dedicated button for device firmware update mode
- Up to +4 dBm Output – BLE radio power
- 19 GPIO Pins – 8× 12-bit ADC, up to 12 PWM outputs (3 modules × 4 channels)
- Built-in USB Serial – For programming and debugging via command line
- LiPo Battery Support – JST connector with built-in charger and battery voltage monitoring
- Compact Design – 51 mm × 23 mm × 8 mm, weighing 5.7 g
Also Available
- Feather nRF52 Bluefruit LE – Same hardware with Arduino IDE support
- Feather nRF52840 Express – Upgraded nRF52840 with USB native, 1 MB flash, CircuitPython
