Review on SaiDian Controller Driver Indicator Support by Andrew Cramer

Used this to convert an all in one Android POS kiosk so that it could be controlled by a Raspberry Pi 4. It worked great right out of the box, although I saw the same random noise that other reviewers reported. I work with electronics and have some knowledge in manufacturing. When I looked at the circuit board, I first thought that the electrolytic capacitors looked like junk. Having swapped them out (there are 2 of them), I am happy to report that I no longer observe any noise! The black color is dense and clean.
