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. Important: This board is for advanced users only. It uses the Apache Mynewt RTOS, not Arduino IDE. You cannot easily switch between Mynewt and Arduino without an SWD programmer. If you want Arduino IDE support, use the Feather nRF52 Bluefruit LE instead. 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 Note: Mynewt development tools require a POSIX-type system (Linux, macOS, or MinGW).
