For sale is my HiFiBerry Digi-B+ Board. 'B+' because it is the version with the output transformer. It is a high quality S/PDIF output board for Raspberry Pi models A+, B+ and RPi 2 & 3. This board facilitates a signal from the RPi to your external DAC. It is the standard (not Pro) version.

This board has had less than 100 hours use and is in perfect condition. A new item including postage costs £38.90.
