1.28-inch round color display features Raspberry Pi RP2350, motion sensor, GPIO headers, metal case - CNX Software

Waveshare has recently launched the RP2350-LCD-1.28, a Raspberry Pi RP2350-based 1.28-inch round color display module with 240×240 pixel resolution and a 65K-color IPS panel. This board also features a rechargeable Lithium battery manager, a 6-axis IMU with a 3-axis gyroscope and accelerometer, multiple GPIO pins, and a USB Type-C connector for programming and power. Additionally, it supports USB 1.1 host/device support, temperature sensor, and 24 PWM channels, all configured for flexible I/O options. These features make this device useful for IoT, wearable tech, and embedded applications. The company also provides an optional CNC metal casing that provides durability and heat dissipation for portable or rugged applications.

We have previously covered similar development boards with a round display such as the RP2040-powered 0.99″ rounded display, the ESP32-S3 LCD Driver Board, the SB-Components has launched Dual Roundy, and others, but it’s the first to feature the RP2350 microcontroller.

RP2350-LCD-1.28 specification:

Since the display is built around the RP2350 MCU, it can be programmed with the official Pico C/C++ and MicroPython SDK, as well as the Arduino IDE. The company also mentions there are “comprehensive SDK, dev resources, tutorials to help you easily get started” but at the time of writing their wiki page is empty.

We still get detailed specifications, details about the charging IC, IMU, flash memory, etc.., as well as a pinout diagram of the board to help users get started.

The RP2350-LCD-1.28 development board can be purchased from AliExpress for $18.01 (or $22.53 with the metal enclosure) and on Amazon for $25.99. You can also check out the official Waveshare store where it is priced at around $16.99 excluding shipping.
