Breakout Board Board Power The iCE40HX-8K evaluation board is powered with the USB cable. LED location D11 indicates that the board is powered up. All I/Os are driven at 3.3v. Board I/Os The I/Os that feed the holes and the 0.1” connector are driven at 3.3v levels. Location J2 is the populated 2 x 20 row connector.
J6:1-2 and J6:3-4. Jumper J7 is not installed. See Figure 5 Figure 5. CRAM Programming LED in location D10 is connected to the CDONE pin of the iCE40HX-8K. This can be monitored to determine that the iCE40HX-8K is programmed correctly.
