Power Supply
3.3V and 1.2V power supply rails are converted from the USB 5V interface when the board is connected to a host
PC.
Test Points
In order to check the various voltage levels used, test points are provided:
• TP1: +3.3V
• TP2: +1.2V
• TP3: GND
USB Programming and Debug Interface
The USB mini-B socket of the Breakout Board serves as the programming and debug interface.
JTAG Programming: For JTAG programming, a preprogrammed USB PHY peripheral controller is provided on the
Breakout Board to serve as the programming interface to the MachXO2 FPGA.
Programming requires the Lattice Diamond or ispVM System software.
