  1. Because UART0 is already used as debug, as you guess. Why not use UART1 /dev/ttyS1 (Pin #8 = TX, Pin #10 = RX)? (I use mainline kernel) mkdir /sys/kernel/config/device-tree/overlays/uart1 cat /boot/dtb/overlay/sun8i-h3-uart1.dtbo > /sys/kernel/config/device-tree/overlays/uart1/dtbo reboot
  2. But if I power the LCD and I2C module with 3.3V, it shouldn't output 5V, right?
  3. For Windows, open "Device Manager" There will be item "Gadget Serial v2.4" Get the driver Then just use Putty
  4. You can power on/off the LED of the LCD using digital pins, not the power pins. May need resistor.
  5. Instead of controlling LCD ILI9341 with the Orange Pi as in the video, I'm thinking of using ILI9341 as the Orange Pi Zero terminal display. But then I'll may end up got very tiny unreadable font. Can it be done directly, or I will need Arduino to read the Orange Pi serial console and drive the LCD?
  6. There are labels 1. USB_DM3 (USB#3 D-) 2. USB_DP3 (USB#3 D+) 3. USB_DM2 (USB#2 D-) 4. USB_DP2 (USB#2 D+) The 5V and GND are from the GPIOs (I think), or may be take it from DCIN (5V)/GND near power jack J1. Good luck, I want to see the result
  7. (It's not wrong device: I have already known Opi1 to only have two USB ports/no IR recv/no TV out/etc when placing order and even knew nothing about those solder points back then. It's just good if I can use them.)
  8. I just received my opi1 yesterday. then now I see that the solder points are so tiny and wonder how one could solder wires there.
