Pine64 PineNut Model-12S

Overview

The Pine64 PineNut Model-12S is a castellated stamp module based on the Bouffalo Lab BL602 RISC-V SoC, designed in the ESP-12S form factor for direct SMT soldering onto custom carrier boards. With 16 castellated pads exposing 11 GPIOs, the 12S provides significantly more I/O than its sibling the PineNut-01S, including full SPI, SDIO, JTAG, multiple ADC channels, and a DAC output.

Measuring just 16mm x 24mm x 3.1mm, the module packs WiFi 802.11 b/g/n and BLE 5.0 connectivity with an integrated PCB trace antenna. The fully multiplexable GPIO architecture of the BL602 allows each pin to be configured for UART, SPI, I2C, PWM, ADC, or JTAG via software, giving designers maximum flexibility in their PCB layouts.

The PineNut-12S is the same module used inside the PineCone BL602 evaluation board, making firmware developed on the PineCone directly compatible. Available in tape-and-reel format for production runs, the module is ideal for manufacturers building open-source IoT products on a RISC-V platform at scale. It shares the full BL602 ecosystem including the BL IoT SDK, Arduino core, NuttX, embedded Rust, and OpenBeken firmware.
