Today we begin testing a new design of PiSugar.
There will be i2c power level detection (for soft shutdown), RTC, UPS, a gpio button.
It turns out that the power IC we use has i2C but has nothing to do with power level detection....sigh....so we are about to change another model.
Sugarpin samples also arrived. Still need some modifications. Anyway it's probably the tiniest structure we had ever made. BTW it's gold plated !
