LEDs

Ring LEDs

RingLEDs.jpg

  • D3-D14 = Ring LEDs
  • D15 - CH340 USB Rx (in to card)
  • D16 - CH340 USB Tx (out of card)

RTS/CTS Rework

CH340T Pinout.PNG

  • Board uses CH340 USB to Serial I/F
  • Hardware handshakes are in the CH340 IC but not wire on the board
    • This is an issue for slower serial emulations which need to throttle the host CPU
  • Remove LEDs D9, D10
  • Add wire D9 (left side) to U6-11 (CTS) (in to CH340)
    • FPGA PIN_77
  • Add wire D10 (left side) to U6-16 (RTS) (out of CH340)
    • FPGA PIN_76
