I have both a 1541 and several 1541-II. However, they are fully compatible with each other anyway. This is probably different with the 1571 and 1581, so there might be...

If the 1571 has a 1541 compatibility mode then it will probably work. But things look significantly different with the 1581. The problem is that for speed reasons I didn't...

Great, thanks for testing it out!

Hi, the charging input (+5V) is passed to the output (VOUT) via the diode (D1). At the same time, the charging input is connected to the gate of the MOSFET...

Yes, of course, it's all open source. I'll put it on my to-do list, which is pretty long now ;-)

Hi, the data lines on this board are not routed to the outside as it is not necessary for the intended purpose. The CH224K is of course connected via the...

If you only want to use USB-PD as a charging protocol, then that shouldn't be a problem overall. USB-PD only uses the CC lines, you no longer have to connect...

Yes, I actually wanted to create a uniform software for all devices that would then automatically recognize which device was connected. But at the moment I don't have the time...

Yes you are right. There is a small flaw, the battery feedback after the resistor would be a little less prone to noise. But it also works fine this way.

No.
