Thanks Pascal. I feel a little embarrassed asking more questions, but hopefully the only silly question is the one I dont ask!
How do I make the USB wiring harness?
Do I need all 8 wires from the "USB" header on the paparazzi going to the corresponding pins on the USB connector? Or is it enough to have Pin 1 (GND), Pin 2(+3.3V), Pin 3(USB+), Pin 4(USB-), and Pin 5(VBUS) only connected?
Does the USB power the Tiny during flashing the AP? Or do I still need external power supply connected to the Tiny?
Thanks for being so patient!
