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 circuit, six-axis sensor (3-axis accelerometer and 3-axis gyroscope), real-time clock (RTC), buzzer, and other integrated peripherals for convenient development and product integration. It is powered by the RP2350A microcontroller, featuring a dual-core ARM Cortex-M33 processor and dual-core RISC-V (Hazard3) processor, with a maximum clock frequency of 150 MHz. The board includes 520 KB of SRAM and 16 MB of on-chip flash memory. It uses a USB Type-C interface for easy, reversible connectivity. Built-in USB 1.1 host and device support enables versatile connectivity options. The board supports drag-and-drop program loading via USB mass storage mode. Additional features include low-power sleep and hibernation modes, an onboard temperature sensor, precise on-chip clock and timer, RTC battery interface, and lithium battery charge/discharge interface for portable applications.
