I subscribe. There is no higher capacitors for motor load, no VCC filtering, 3.3V unbuffered pins near 5V VCC, unclear/unwanted supply of the board on the same rail with the motors ... what can go wrong ?The board looks quite poor overall - not only is there the lack of protection between the 5V-supply servos and the Pico GPIOs, the layout of the power supply regulator looks really poor, with no attention given to keeping the high frequency loops short.
Also the "servo driver" name is very misleading, there's no motor driver, it's just a careless breakout coupled with a very flimsy power supply. And I bet it's overpriced like many other Waveshare products.
Though, I own one which I like very much, RP2040-PiZero Development Board, it's looks like a Zero, but it's RP2040 with PIO USB, DVI SD-CARD, and an RPI style GPIO connector (hand to use a ribbon cable between RP2040 and a real ZERO) https://www.waveshare.com/rp2040-pizero.htm
