Control Board doesn't appear to be powered when piggy backed on to Arduino

#1

Hi All,

I am attempting to flash the firmware on to the control board, but when I piggy back it on to the Mega no power LED comes on.

The power LED on the Mega is lit however and connected to the computer via usb.

Any ideas on what the problem might be?

Do you have the jumpers set to power the board from the power supply (recommended)?

If so, the power supply does not turn on until you connect to the control board over the serial port (i.e., when you start MicroDrop).

I am powering it from the serial cable. The lights on the Arduino have turned on, but not the power light on the control board.

Another issue is the command for flashing the firmware doesn’t appear to work with Microdrop 2.0 as the file structure is different.

Hi Henry,

I’ve update the instructions to work for MicroDrop v2.0.

Re: the LEDs, there are 2 on the control board: PWR and USB. The USB light should be on if the Arduino is plugged in by USB, but the PWR light will not turn on unless the PSU is enabled (this happens when the MicroDrop connects to the Arduino’s serial port).

Does that help?
