Some important safety questions, I am pretty new with microcontrollers, so I use them as recommended out of the box:
-
After taking a closer look at the XIAO models available, there’s a warning about adding any batteries with USB-C at the same time for RP2040 chips. I hadn’t expected this. I have the sense model which does use LIPO 3.7v rechargeable batteries. But it also recharges. Likewise like the ESP32C3, it does do a LIPO recharge.
-
Could automatic recharge cause conflict with using a simple alkaline AAA/AA battery adapted case or does the buck booster prevent feedback to the batteries if you plug in the USB-C while having dry cells attached? What are the risks compared to using something like the RP2040 model? Is recharge automatic?
