The Lipo charge LED is faintly lit when VBUS = 0V, likely due to backpowering from the MCP73831.
Solution: Power LED from VBUS instead of 3V3. Check if 220 Ohm is still sufficient, as VBUS is 5V.
One of the registration pins of the Debug connector is larger than the other, but both NPTHs are the same size, so one is a very tight fit.
Fix footprint according to datasheet: https://www.we-online.com/components/products/datasheet/490107670412.pdf
OUTPUT_TIP
is currently assigned to PB0
which interferes with the STM32 clocks.
Pin should be left floating and OUTPUT_TIP
assigned to another GPIO.
Adding the capability to easily add I2C sensors etc. might be a good idea to increase versatility and reuse.
PB6
and PB9
of I2C1
are not currently used and could support a QWIIC connector footprint.
Underneath the MCU there is a lot of free board space. The Ultramote Logo could be added here!
