The board measures just 25.4mm × 44mm and integrates the BL602 via a PineNut 12S stamp module, providing WiFi 802.11 b/g/n and Bluetooth Low Energy 5.0 in a breadboard-friendly form factor. The BL602 SoC features a 32-bit RISC-V core (SiFive E24) clocked at up to 192MHz, with 276KB SRAM, 128KB ROM, and 2MB of onboard flash. All 16 GPIO pins are fully multiplexable — any pin can be assigned to UART, SPI, I2C, PWM, ADC, or JTAG via software configuration. The board includes a CH340 USB-to-serial bridge for easy programming through USB-C, an onboard tri-color RGB LED connected to GPIO11/14/17, and a dedicated JTAG header for hardware debugging. The PineCone enjoys strong community support with multiple firmware options including the official BL IoT SDK (FreeRTOS-based), Apache NuttX RTOS, Arduino via Pine64's ArduinoCore-bouffalo, embedded Rust through Sipeed's bl602-hal, and OpenBeken for smart home integration. The board's extremely low price point and open hardware design make it an accessible entry point for RISC-V embedded development, IoT prototyping, and wireless sensor network projects. ## Where to Buy - [Pine64 Store](https://openhardware.directory/r?to=https%3A%2F%2Fpine64.com%2Fproduct%2Fpinecone-bl602-evaluation-board%2F&ref=openhardware.directory&product=pine64-pinecone-bl602&source=md-export) — $3.99 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fpine64.com%2Fproduct%2Fpinecone-bl602-evaluation-board%2F&ref=openhardware.directory&product=pine64-pinecone-bl602&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fpine64%2Fbl602-docs&ref=openhardware.directory&product=pine64-pinecone-bl602&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwiki.pine64.org%2Fwiki%2FPineCone&ref=openhardware.directory&product=pine64-pinecone-bl602&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Ffiles.pine64.org%2Fdoc%2Fdatasheet%2Fpine64%2FBL602_BL604_DS_1.2_en.pdf&ref=openhardware.directory&product=pine64-pinecone-bl602&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Ffiles.pine64.org%2Fdoc%2FPinenut%2FPine64%2520BL602%2520EVB%2520Schematic%2520ver%25201.1.pdf&ref=openhardware.directory&product=pine64-pinecone-bl602&source=md-export) ## Tags `risc-v`, `wifi`, `ble`, `iot`, `bl602`, `pine64`, `open-source` ## Images ![Pine64 PineCone BL602](https://nbg1.your-objectstorage.com/openhardware-directory/entities/pine64-pinecone-bl602/14c2f12ab7a7.jpg) ![Pine64 PineCone BL602](https://nbg1.your-objectstorage.com/openhardware-directory/entities/pine64-pinecone-bl602/98a739de9215.jpg) ![Pine64 PineCone BL602](https://nbg1.your-objectstorage.com/openhardware-directory/entities/pine64-pinecone-bl602/04346c0477ce.jpg) --- [View full device page](https://openhardware.directory/devices/pine64-pinecone-bl602)
