I have two Open Xeniums for sale. (They do not have the J1 connector)...
I'm asking $50 + shipping.
The J1 connector was supposed to ship from DigiKey on 6/19/2022... however, they do not have an update.
If you want to wait, i'll sell them for $55 + shipping after I put the connector on it.
Feel free to ask questions. They are updated to XeniumOS 2.3.5 and ready to roll with 2x7 LPC header.
