The STAR Momentary firmware does not include any memory options or saving functions, so that part would need to be made up from scratch or transferred from a clicky firmware. I’m really not a firmware guy, but I think it is possible.
.
This can be done.
- ATtiny85,
- C2 closer to MCU,
- indicator LED to pin3, very well.
Anything else?
While I’m already sketching the board…
Could you give me some input, just to know if I might omit options if the space was needed.
- Is the outer diameter of the Q8 board (46.02 mm) enough or would the “ears” of BLF SRK FET still be needed?
- As momentary switch pin2 is most commonly used, is pin3 for the switch an option at all anymore?
- There was talk of a snubber circuit for the FET, is that still in discussion?
- what for are in Q8 (v3) the two small rectangular pads above BATT LED?
- Is the Zener Diode in Q8 the usual Zener-Mod-Diode and not necessary with an LDO version?
Any feedback is welcome.
