Hi what audio amplifier chip is in use on the MangoPi-R3c? The marking on the chip does not match anything I can find online.

According to
https://mangopi.cc/Tiny200
it's a PAM8403, but this is just silly as that's a 6 Watt Stereo chip.

According to the schematic, it's a PAM8301, but first that part is discontinued, and also the PAM8301 should have a chip marking of FPXYW, which does not match the chip on the MangoPi-R3c board.

What make and model audio amplifier chip is it? I need to match a suitable speaker

The camera firmware does not work with the MangoPi - see my forum post here
https://www.dfrobot.com/for...

It just displays a green square image. What is the solution for this ?

We are very sorry.
Our engineers have updated the software tool and you can retest it.

I got mine working now - using windows - dont bother using Zadig 2.5 - just run the tool - hold the boot button, and press reset and let go of reset (so it boots to the right bot mode). Then write each of the 4 binaries to the device. Doing the hold buttons of boot and reset after each binary is written. Then reset at the end.

Good luck. DFRobot are at the mercy of whatever MangoPi decide to do, and they're focussed on the MangoPi-MQ Pro. Support is not a strong point for MangoPi, which is sad because I felt the R3 had potential.
