A CH552G Devboard In Case You Missed It

The board shown in real life, top and bottom, showing the pinout and alternate functions silkscreened.

We might just never get tired of covering cool small cheap MCUs, and CH552G sure fits this description. Just so you know, here’s a Hackaday.io project you should check out – a CH552G devboard that’s as simple as it sufficient, in case you needed a tangible reminder that this chip exists, has a lively community, and is very much an option for your projects.

The devboard design by [Dylan Turner] is so straightforward, it’s almost inspiring – a square of PCB with the chip in the center and plenty of empty space for your mods. Everything is open-source with KiCad sources stored on GitHub. The most lovely aspect of this board, no doubt, is having the pin mapping written on the bottom, with all the alternate pin functions – you won’t have to constantly glance at the datasheet while wiring this one up. Plus, of course, there’s the microUSB port for programming, and the programming mode button that a few CH552 projects tend to lack.

It’s simple, it’s self-documenting, it’s breadboardable, and it’s definitely worth putting into the shopping cart at your PCB fab of choice. Oh, and there are bringup instructions on GitHub, in case you need them. Whether you want to prototype the cheapest macropad or keyboard ever, or perhaps a reflow hotplate, the CH552 delivers. If these CH552 projects aren’t enough to light your fire, here are a dozen more.
