ThomasEDIT: I received both the XY-LPWM and XY-PWM board yesterday. As expected, the Nuvoton chip on the XY-LPWM had to be replaced by a STM8S003F3P6, and a 1uF 0603 capacitor had to be added, but that was quickly done. The XY-PWM for $1.65 came with the required controller, and both worked right after flashing - nice work @Ivan Alf!
=======================================================
@Ivan Alf contributed board support for the Chinese board XY-LPWM in his GitHub fork plumbum/stm8ef:
I never understood what people use "PWM boards" for, but this one, and the slightly cheaper 2CH PWM Generator board both provide a serial interface. Which is really nice for interactive Programming with Forth!
The board provides a 2x4 digit LCD display with a HT1621 LCD controller:
Like many STM8S003F3P6 based boards these days, there is a big risk that the board you rceive has a "pin compatible" Nuvoton N76E003AT20 µC, a controller with an 8051 like core. Better be prepared to do some soldering when you order this board!
Hint: sometimes STM8S103F3P6 chips are cheaper than the lower rated STM8S003F3P6.

Hello. I placed partial teardowned XY-PWM pictures here: http://tuxotronic.org/xy-pwm/
You can use them on your own.

By the way, I have also 2ch modules XY-PWM (also know as HW-0515) modules ;-)
And I even showed on the LED display the inscription '4th' =)
All three two-channel modules, which I ordered from different vendors, were on the MCU STM8S003F3.

Ah, the XY-PWM - I've seen this coming and ordered one. I was curious whether this is a safer choice than the W1209 (which has more often than not a Nuvoton 8051 chip nowadays).
It's high time to add more boards to the Wiki :-)

Works!
