Strange. After changing the pins to 5 and 6, I don’t have to mess with the 5v pin anymore.
Did you change the code to comment out a line in?:
# Enable logging
logger:
hardware_uart: USB_SERIAL_JTAG
level: DEBUG
When I check logs I don’t see this line like in yours:
[16:59:39][C][logger:296]: Hardware UART: UART0
Instead I see:
[10:09:15][C][logger:296]: Hardware UART: USB_SERIAL_JTAG
