I have a used JustBoom Digi HAT Digital Audio Add-on Board for Raspberry Pi for sale that I am no longer using as I just upgraded my amp and it has allowed some simplification.
Used like new in original packaging. Will be shipped with a free black plastic Just Boom Digi Hat case. I am asking for $24 with $4.99 for shipping for both items and I will ship to North America only. The case was originally sold for $20.
The listing is on the Amazon market place - I would prefer to handle this as it does all the transaction stuff with minimal fuss.
