- IMPORTANT! Add solder to the USB-C connectors retention pins before connecting an USB cable for test. Important in hindsight!
- Solder bridges on the STM32 in a LQFP64 package, use a solder iron and flux to drag off the excessive solder.
- Solder bridges on the USB-C connectors, resolder with the hot plate, but add flux on the component side and the PCB.
- Use the AL1-1LM1 PCB with pins to align J4 and J5 on AL1-MB1 accurately.
- Add 2 x test points at bottom layer, for USB_DN and USB_DP for the ESP32.
- Increase the surface area on the pads of the USB-C connectors retention pins.
