Compact round-display MCU for wearable prototypes

This WaveShare development board pairs a Raspberry Pi RP2040 dual-core Arm Cortex M0+ running up to 133 MHz with a 1.28inch 240x240 pixel IPS LCD showing 65K colours. Onboard 264KB SRAM and 2MB Flash plus a lithium-battery recharge header make it suited to portable sensor nodes and smart-badge projects. All GPIO and debug pins are broken out on 1.27mm pitch female headers for rapid integration.

Makers needing a tiny circular screen

Engineers building wrist-worn displays, badge-sized data loggers or handheld UI mock-ups will benefit from the integrated accelerometer, gyroscope and round panel. Projects that require wireless connectivity, a rectangular display, or larger memory footprints should evaluate other platforms.

Onboard 1.28inch 240x240 round IPS panel decides fit

The circular 65K-colour LCD and its 1.27mm header layout define the mechanical envelope and pin assignment; verify that your enclosure and peripheral connections match this form factor before committing.

Questions about this item

What USB standard does the Type-C connector use and what is the practical speed limit?

The board uses USB 1.1 with device and host support, so the practical speed limit is 12 Mbit/s.

How many pins are on the 1.27 mm pitch female headers and what should I check before using them?

There are 30 pins in total, but some are connected internally; consult the wiki for multiplexing details before wiring.

How do I program the RP2040 and what common step causes the board not to appear as a drive?

Hold the BOOTSEL button while plugging in USB to enter mass-storage mode, then drag the UF2 file onto the drive; forgetting BOOTSEL is the usual mistake.
