JustBoom DAC HAT
Discontinued
The JustBoom DAC HAT is a plug-and-play, high-resolution digital-to-analogue converter for the Raspberry Pi. Simply stack the HAT onto your Raspberry Pi and enjoy high-quality audio playback within minutes — no soldering required.
Featuring a 384 kHz / 32-bit DAC chip with hardware volume mixing and a built-in 138 mW headphone amplifier, the DAC HAT outputs line-level audio over RCA and amplified audio over a 3.5 mm jack. It uses the I2S interface for audio input, reducing CPU load compared with USB solutions, and is powered directly from the GPIO header with no extra cables needed.
