JustBoom introduced a new product line with their new sound cards for the Raspberry Pi Zero. The Pi Zero with its more compact format is very useful for IoT or portable projects. Now the Zero variations of the JustBoom DAC, Digi and Amp sound cards are available, complementing the Raspberry Pi. Despite the smaller size, the Zero sound cards are quite powerful, making them ideal for everyone who wants to build smaller projects but still enjoy uncompromizingly great sound quality.
