I've had a nice new specimen of Chinese power-circuit-bending on my desk: the W1209WK. The schematics is a good demonstration of "what not to do with a µC and a LED", even more so than the venerable "DC/DC with Voltmeter".

It was quite challenging to work around the worst quirks of the circuit, but the board is now documented, and there is preliminary board support.
