ISL12022M RTC breakout board

This is a breakout board for the Intersil ISL12022M real-time clock, with optional I²C pull-ups and a CR1225 backup battery. The circuit is based on the design recommended by Intersil, with a few tweaks. It’s the second board I’ve designed so far.

Combo board for the Raspberry Pi with IR receiver and transmitter along with Real-Time Clock and coin cell battery:

Raspberry Pi IR receiver + IR transmitter + RTC

I needed an IR receiver for my Raspberry Pi which I use as an internet TV receiver [..]  Solution: make my own.
