iCE40 Ultra Breakout Board
Introduction
Thank you for choosing the Lattice iCE40 Ultra™ Breakout Board.
This guide describes how to begin using the iCE40 Ultra Breakout Board, an easy-to-use platform for demonstrat-
ing the high-current LED drive capabilities of the iCE40 Ultra FPGA. Along with the evaluation board and accesso-
ries, this kit includes the pre-loaded LED Driver Demo that demonstrates driving the RGB LEDs with a PWM circuit.
In addition, most of the device's I/O balls are accessible via one of the several header locations on the board, facil-
itating rapid prototyping of user functions.
The contents of this user’s guide include demo operation, top-level functional descriptions of the various portions of
the evaluation board, descriptions of the on-board connectors, shunts, a complete set of schematics and the bill of
materials for the iCE40 Ultra Breakout Board.
Note: Static electricity can severely shorten the lifespan of electronic components. Be careful when handling the
iCE40 Ultra Breakout Board as to not damage it from ESD.
