Selecting FTDI Voltage - nolamakerfaire/2016-VIP-Badge GitHub Wiki

Some modification is needed if you want 5v available for components from the FTDI programmer's USB bus.

To modify, you must follow these steps:

• Change the USB FTDI Programmer to select 5V. First, cut the trace between the right and middle pads.

Second, use solder to bridge the left and center pads.

Once modified, the FTDI programmer will provide 5v over the VCC pin. If you are using the FTDI programmer with the Arduino Pro Mini, you need to make sure that only 3.3v is being provided to the microprocessor. This is done by modifying the board to send the 5v to the Raw power bus. See https://github.com/nolamakerfaire/2016-VIP-Badge/wiki/Powering-the-Badge for details.
