Mini 1.54" watch PCB with touch support
martinberlin opened this issue · comments
The new idea for a PCB is to get as tiny as possible having the already existing Tinypico controller but using instead:
- DS3231MZ (LCSC part C107410) guess without backup battery since there will be no space
- Cheap version 1.0 with PCF8563T instead and a 100 nF Tantalium Capacitor as backup power source (No temperature)
- Touch connector 6 FPC (Mind right ones)
- Mini battery charger TP4057
Schematics starting to take form.
