LEDs
A blue LED (D1) is used to indicate USB 5V power. Eight red LEDs are driven by I/O pins of the MachXO2/MachXO3
device.

Power Supply
3.3 V and 1.2 V power supply rails are converted from the USB 5 V interface when the board is connected to a host
PC.
Test Points
In order to check the various voltage levels used, the following test points are provided:
• TP1: +3.3 V
• TP2: +1.2 V
• TP3: GND
USB Programming and Debug Interface
The USB Mini-B socket of the Starter Kit serves as the programming and debug interface. For JTAG programming, a pre-
programmed USB PHY peripheral controller is provided on the Starter Kit to serve as the programming interface to the
MachXO2/MachXO3 FPGA. Programming requires the Lattice Diamond or ispVM System software.
