Hi

Please check topic on Twitter about to change power switch from slide to tact version.

I'm just thinking to change the current slide switch.

This change will delay project about 2 days (extra design), but without extra costs (I'm trying to use cheap MCU).

Extra features:

- logic from LTC2954:

LTC2954 Datasheet and Product Info | Analog Devices


After shutdown OS 5V power supply rail can be automatically turned off.

Extra features for the future (not for REV1.1 -> needed firmware):

- wake up mode from RTC (alarm)

- standby mode -> driving status 2 LEDs RED/GREEN

- wake up from IR remote control
