RP2040 RGB LED Matrix Tiny MCU Board Based On Raspberry Pi RP2040 Microcontroller Chip with 5×5 RGB LED Matrix for Colorful Lighting Display, with USB Type-C Port,Support Arduino,C/C++, MicroPython

Neat little board, tiny, the LED patch covers about a cm^3. I have a bunch of rp2040s and just wanted something convenient.However, a few minutes after having it plugged, before I even got to programming it, an LED developed a flicker and started getting stuck on. I thought, maybe it's just TX/RX.. Not that I like the differential wear that would cause, but now that I've programmed it to ensure the rp2040 isn't doing anything and had some time to watch it, the led flicker is obviously coupled to a power regulation issue and possibly an intermittent short.1 star because a 5 minute test would have caught this if they did any QC. I suppose I'll try reflowing it or frankensteining a dev board, but I paid 3x the cost of a usual rp2040 dev board to not have a hack. $15 simply isn't worth driving 20 miles to UPS to return this in time. I might try reflowing it. NEver again though, just make your hats people, you can replace them.
