This is an RP2350-based development board from Waveshare, with a compact 1.64″ AMOLED touch displayalong with a bunch of cool features making it a useful option for a range of projects.

The RP2350 needs no introduction but we’ll do it anyway – it’s microcontroller chip designed by Raspberry Pi, with a unique dual-core and dual-architecture design with dual ARM Cortex-M33 or dual Hazard3 RISC-V processor support, a flexible clock running up to 150 MHz and 520KB of SRAM, supported by 16MB onboard flash.

The display is a 280×456 1.64″ AMOLED panel, offering 16.7m colours, controlled via QSPI. It supports touch input via I2C, so you can use it as a simple interface for your project without the need for buttons or other inputs.

The board is powered and programmed via USB-C, alongside a PicoBlade-compatible/MX1.25 connector for a LiPo battery (battery not included, but we stock PicoBlade-compatible LiPo batteries in the store). The LiPo battery will be charged when USB-C power is connected, thanks to the onboard charge circuit.

You’ll also find amicroSD card slot for storage, a 6-axis IMU (3-axis gyroscope and a 3-axis accelerometer), and the usual BOOT/RESET buttons and indication LEDs (power/charge).
