vr@m reacted to martinayotte in Help on Buffer strength GPIO
As I've said earlier, it 20mA per pin ! I've also said that if you sums up many pins, it is up to the quality of the PCB design if it could handle that, for your example 40 pins multiply 20mA, this means that the VCC would need to supply a total 800mA to the SoC, if VCC lines on PCB are not huge enough, this will produce a voltage drop on those lines and maybe the SoC will brownout and reset/crash.
vr@m got a reaction from Igor in I can't find the script.bin file to change hdmi resolution
Thank you @martinayotte, I will try this image. You and Igor gave too good reasons to change to armbian.
