LILYGO T-PICO-2350

Introduction
The T-Pico2350 is another version in the T-Pico series, designed and manufactured based on the Raspberry Pi RP2350 chip. It features an external expansion case design similar to the T-Display S3 Pro. This case is designed with multiple external expansion interfaces, supporting both pin header expansion and a 13-pin 0.3mm pitch FPC expansion interface. Additionally, the bottom is equipped with multiple M1.4 embedded brass nuts for secure expansion and mounting.
The device integrates RP2350 + ESP32-C6, a 2.33-inch capacitive touchscreen, TF card slot, HDMI interface, two QWIIC interfaces, and a PMU (Power Management Unit). It supports both battery power and USB power. The USB interface follows the T-Pico series design, allowing programming of both chips regardless of the insertion direction.
