In Version 2 of this board, the on-board USB cable circuit has been updated.
1. A USB RESET# pushbutton has
been added. The Version 1 board
includes a single Reset pushbutton
that resets both the LatticeECP2
FPGA and the USB cable. The
addition of the USB RESET# button
allows the FPGA to be reset
independent from the USB cable
circuit.
2. In the Version 2 board, the MachXO device has been changed from a
MachXO640 to a MachXO2280 device.
