1. Introduction
This guide describes how to begin using the iCE40 Ultra™ Breakout Board, an easy-to-use platform for demonstrating
the high-current LED drive capabilities of the iCE40 Ultra FPGA. Along with the evaluation board and accessories, 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 through one of the several header locations on the board, facilitating rapid
prototyping of user functions.
The contents of this user guide include demo operation, top-level functional descriptions of the various portions of the
evaluation board, descriptions of the onboard 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.
