Would anyone know if this driver has an output for switch leds?
Searched but cant find anything.
The ‘stock’ driver firmware won’t have it, but if you contact Richard, he MIGHT be willing to flash with another firmware that does, with you acknowledging that there is no warranty support on ‘non-stock’ firmware. Then, it will just be a matter of soldering the leads at the correct pins on the MCU, which he may also do, for a small price addition.
Thank you.
Oh, another thing… He may have to change the MCU to ATtiny25. I can’t remember if there exists a firmware for ATtiny13 that has output for switch LEDs. For that answer, you should ask TomE or ToyKeeper (or maybe even Richard).
Again thank you.
I think things have moved on since a board covered in 7135s.
You might contact Lexel and see what he can offer, e.g. a “triple-down” driver, with a single 7135, a bigger bank, and a FET, together with recent firmware and switch LED control.
He is EU based too.
Well, yeah, that too.
