The Desk of Ladyada - Stemma Sunday & VFD Vunday
This weekend we got a LOT done with new and revised stemma boards! For revisions, we got, assembled, and tested the DRV2605 and ADS1x15 QT boards - both work great. we also put together and tested our qt py lipo BFF and it works great, for our final version we added a battery monitor resistor divider. in order to test the BFF we needed a power monitor like the INA219 and realized at like 1am that we didnt have an INA219 on us, so we ended up bringing up the INA228 prototype we had and wrote a quick driver for it. Unfortunately the INA228 is totally unavailable so it won't be in the shop soon…
