About the ICE40-DAC Rev A PCB

ICE40-DAC Rev A is an open source PCB design by OLIMEX, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 30 × 50 mm, with 39 components from 20 distinct parts.

Other key parts include the THS5641AIDW(SOIC28) and SN74ACT244DWR(SOIC-20). By type, the board carries 13 capacitors, 12 resistors, 2 ICs, 2 inductors and 1 transistor.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

DAC expansion board for Olimex iCE40 main boards

Adds fast Digital-Analog-Converter (DAC) functionality to the main board.

You can effectively use up to 4 x iCE40-DAC with a single EVB board (or up to 2 x iCE40-DAC when you have iCE40-IO connected to the same bus).

You can use the exported PDFs to access the schematic or the bill of materials.

We used the latest KiCad night builds to create the design. Please use a new version KiCad to open it.
