Description

The Waveshare RP2350-Touch-LCD-2.1B is designed for the development and prototyping of devices with graphical user interfaces. The board is based on the RP2350B microcontroller designed by Raspberry Pi and features a dual-core architecture with a choice between ARM Cortex-M33 cores or Hazard3 RISC-V cores. The microcontroller operates at a clock frequency of up to 150 MHz and includes 520 kB of SRAM and 16 MB of onboard Flash memory, with the option to expand using external PSRAM.

The board integrates multiple peripheral components, including a 6-axis IMU, an RTC chip, a TF card slot, a buzzer, and a 3.7 V lithium battery connector with charging support. Available communication interfaces include SPI, I2C, UART, ADC, PWM, and programmable PIO blocks. Programming is supported using C/C++, MicroPython, and the Arduino IDE, with USB mass storage mode available.

The 2.1B version is equipped with a 2.5D curved capacitive touch panel.
