Waveshare RP2350B 2.1-Inch IPS Capacitive Touch Round Display Dev Board

Description

This Waveshare development board centers on the Raspberry Pi RP2350B, a unique dual-core, dual-architecture microcontroller capable of running ARM Cortex-M33 or Hazard3 RISC-V cores at up to 150 MHz. It drives a high-quality 2.1-inch round IPS display via an SPI+RGB interface, paired with a capacitive touch panel for intuitive control. The board is engineered for low-power operation, supporting sleep modes to extend battery life in portable and wearable applications.

Beyond the display, the board incorporates a suite of onboard sensors and interfaces critical for embedded systems. The 6-axis IMU provides motion data, while the dedicated RTC maintains accurate timekeeping. A full complement of GPIOs, including SPI, I²C, UART, ADC, and PWM, allows for extensive peripheral expansion. The compact 75x75mm form factor, combined with the integrated flat touch panel, makes it ready for direct integration into final product enclosures for smart watches, industrial dashboards, and automation controllers.
