Waveshare RP2040 MCU Board with 1.28-inch Round Colorful IPS Display

The RP2040-LCD-1.28 is a low-cost, high-performance MCU board designed by Waveshare. Although it is tiny, it incorporates a range of features, including a 1.28-inch LCD round display, a Li-ion battery charger, and a 6-axis sensor (3-axis accelerometer and 3-axis gyroscope). It also has all GPIO and Debug headers adapted, making it easy for users to develop and integrate it into products quickly.

The board is powered by the RP2040 MCU chip, which was designed by Raspberry Pi in the United Kingdom. It has a dual-core Arm Cortex M0+ processor that can run at a flexible clock speed of up to 133 MHz. The board also features 264KB of SRAM and 2MB of onboard Flash memory, as well as a Type-C connector for easy updates and use.

One of the standout features of the RP2040-LCD-1.28 is its 1.28-inch, 240 x 240 resolution, 65K RGB IPS LCD display, which provides clear and vibrant color pictures. The board also has a lithium battery recharge/discharge header, making it suitable for mobile devices.

All of the GPIOs on the RP2040-LCD-1.28 are adapted through 1.27 pitch female headers, with a total of 30 pins (although some pins have been connected to the internal circuit, so users need to be mindful when multiplexing). The board supports USB 1.1 with both device and host support, as well as low-power sleep and dormant modes.

Programming the RP2040-LCD-1.28 is easy, thanks to its drag-and-drop programming using mass storage over USB. The board supports a range of communication interfaces, including 2 x SPI, 2 x I2C, 2 x UART, and 4 x 12-bit ADC, as well as 16 × controllable PWM channels.

The RP2040-LCD-1.28 also features an accurate on-chip clock and timer, a temperature sensor, and accelerated floating-point libraries. Additionally, it has 8 x Programmable I/O (PIO) state machines for custom peripheral support.

The display on the RP2040-LCD-1.28 is powered by the GC9A01A LCD controller, which communicates via an SPI interface. The display panel is an IPS type with a resolution of 240 (H) RGB x 240(V) and a display size of Φ32.4mm.

Waveshare provides comprehensive online development resources for the RP2040-LCD-1.28, including SDKs, tutorials, and support. Users can easily get started with C/C++ or MicroPython programming on this versatile and feature-rich board.
