From the project

A FT232H based production programming jig for the ButterStick

A simple FT232H based programming jig for the ButterStick.

A simple jig made from PCBs that connects to a ButterStick with pogo-pins.

The board supports - Programming/comms over JTAG. - Voltage sensing via an SPI ADC connected to the FT232H's I/O pins.
