12/22 I got some Grove parts including Can Bus adapters from Seeed Studio, some proto boards, and a Pi hat.
Pi Hat
Tutorial is here: https://wiki.seeedstudio.com/Grove_Base_Hat_for_Raspberry_Pi_Zero/
This $9.80 board has its own ARM Cortex M0 MCU. I did not anticipate that, thought it would simply have connectors on it. Seems like I could load custom firmware on it and not even bother to connect a Pi Zero. :-) The firmware package has an Arduino test program in it.
The board includes a 12-bit ADC with 3 analog Grove ports
The UART port passes through to the Raspberry Pi GPIO on GPIO14 and GPIO15
There is a port that lets you burn new firmware into the Cortex MCU.
