Self made FX Mod-Chip (ProMicro supported)

Anyone who want to make their own FX Mod-Chip can try this. I’m now using this circuit and I’m sure that it works well. If your arduboy is using arduino ProMicro which doesn’t contain an OLED_CS, the inverter is necessary. At anytime make sure that your arduboy’s power supply won’t be connected to source higher than 4.6V which may DAMAGE your flash chip.

That’s the best company name ever

I think you are all sleeping now. :laughing: Stay up late?

It’s only 11, I’m working on the test program. Bedtime soon

What program did you draw that in?

It’s daytime now. I draw the schematic to act as the FX Mod-Chip on my home made arduboy. I tried to connect PD6 with OLED_CS. It’s not easy especially when the package of ATmega32U4 is QFN-44. So I use the FX_CS and a one-channel inverter as the OLED_CS.

Looks like EasyEDA.
