Add an audio jack to Raspberry Pi 400 with the DACBerry 400
The Raspberry Pi 400 is a keyboard PC with most of the features of Raspberry Pi 4 SBC, with one of the exceptions being the lack of AV port. But you can now add a 3.5mm audio jack to the Raspberry Pi 400 through the DACBerry 400 S expansion board that connects to the 40-pin GPIO header. It’s a neater way than using a cheap USB audio dongle with microphone and headphone jacks, as it takes less space, and does not occupy any of the USB ports from the Raspberry Pi 400, and it does not prevent you from using the GPIO header.
