Overview
The Pine64 PineNut Model-01S is a tiny WiFi and Bluetooth Low Energy module built around the Bouffalo Lab BL602 RISC-V SoC. Designed in the familiar ESP-01S form factor with an 8-pin through-hole header, the module is ideal for breadboard prototyping and drop-in replacement in projects that previously used ESP-01S modules but want to move to an open-source RISC-V platform.
The module exposes 5 user-accessible GPIO pins (GPIO3, GPIO4, GPIO7, GPIO8, GPIO16) supporting UART, I2C, PWM, and ADC functions. It includes an onboard tri-color RGB LED (red, green, blue) and a push button, making it ready for basic IoT experimentation out of the box. The BL602 SoC provides 802.11 b/g/n WiFi and BLE 5.0 with an integrated PCB trace antenna.
At just $1.99 and measuring 14.3mm x 24.8mm, the PineNut-01S is one of the most affordable open-source WiFi modules available. Full schematics and KiCad design files are publicly available, and the module shares the same BL IoT SDK, Arduino core, and community firmware ecosystem as the PineCone BL602 evaluation board.
