RP2350-Touch-LCD-1.69 is a low-cost, high-performance microcontroller development board with a compact, rounded design. It features a 1.69-inch capacitive touch LCD screen (240x280 resolution, 262K color), lithium battery charging and discharging interface, six-axis sensor (3-axis accelerometer and 3-axis gyroscope), real-time clock (RTC) with battery backup, buzzer, and other integrated peripherals for convenient development and product integration. The board is powered by the RP2350A microcontroller, featuring dual-core ARM Cortex-M33 processors and dual-core RISC-V (Hazard3) processors, with a maximum clock frequency of 150 MHz. It includes 520 KB of SRAM and 16 MB of on-chip flash memory. It uses a USB Type-C interface for easy, reversible connectivity. USB 1.1 host and device functionality is supported. The board supports low-power sleep and hibernation modes, and can be recognized as a mass storage device via USB for drag-and-drop firmware updates. Additional features include an on-chip temperature sensor, precise internal clock and timers, and RTC functionality.
