Thanks for sharing your wingboard. As far as wiring, I have some of the EnviroDIY protoshields that I plan to use. I’m interested in how, physically, you connected the Vbat to your ADC for measurement. Are you using the onboard ADS1115 or an external one? Any photos you can share?

The STC3100 looks interesting. Have you found a breakout board for it, or are you a surface-mount-soldering ninja? 🙂

Best,
