Overview

The LILYGO T-Pico is a family of dual-MCU development boards that pair a Raspberry Pi microcontroller (RP2040 or RP2350) with an Espressif wireless co-processor (ESP32-C3 or ESP32-C6). This combination gives developers the ease of the Raspberry Pi ecosystem for main application logic while offloading Wi-Fi and Bluetooth connectivity to the Espressif chip.

Three main variants are available. The T-Pico C3 uses an RP2040 paired with an ESP32-C3, includes a 1.14-inch ST7789V LCD at 135x240 pixels, and comes with 4MB of Flash. The T-Pico Pro upgrades to an RP2040 + ESP32-C6 combination with a larger 2.33-inch ST7796 LCD at 222x480 resolution and 16MB + 4MB Flash storage. The T-Pico 2350 features the newer RP2350 chip (dual-core ARM Cortex-M33 and Hazard3 RISC-V cores) alongside an ESP32-C6 that adds Wi-Fi 6 and IEEE 802.15.4 (Thread/Zigbee) support.

All variants use a reversible USB Type-C connector and support 5V/500mA charging. The board is programmed using the standard Raspberry Pi SDK toolchain for the RP2040/RP2350 side, and standard ESP-IDF or Arduino for the ESP32 co-processor.

The T-Pico is particularly well-suited for projects that need the rich peripheral support and deterministic real-time capabilities of the RP2040/RP2350 combined with robust wireless networking, such as IoT gateways, wireless sensor nodes with displays, or robotics controllers with cloud connectivity.

Firmware Compatibility

  • Arduino: Supported for both the RP2040 (via arduino-pico) and the ESP32 co-processor.
  • MicroPython: Supported on the RP2040 side via the official Raspberry Pi MicroPython port.
  • CircuitPython: Supported on the RP2040/RP2350.
  • Raspberry Pi Pico SDK (C/C++): Fully supported for maximum performance and hardware control.
  • ESP-IDF: Supported for the ESP32-C3/C6 co-processor.

Flashing Guide

  1. For the RP2040/RP2350: Hold the BOOTSEL button while connecting USB. The board will appear as a USB mass storage device. Drag and drop the compiled UF2 file onto the drive.
  2. For the ESP32 co-processor: Use esptool.py or the Arduino IDE with the appropriate ESP32 board selected and the correct COM port.
  3. Refer to the GitHub repository at https://github.com/Xinyuan-LilyGO/T-PicoC3 for example projects and pinout diagrams specific to each variant.
