I had been evaluating the UniElec U7623 board. We subsequently went with a different board, and I now have some spare hardware to donate:
- UniElec U7623 board
- Metal case (4 x antenna ports with plugs plus 4 more extra drilled holes)
- Various mPCIe Wi-Fi cards (MT7612 x 2 + MT7603)
It is free for anyone who wants to cover actual shipping costs (from Nova Scotia, Canada). If you are an OpenWrt developer, or an educator who will use it in a classroom, then I will pay for the shipping.
Note that the Wi-Fi cards are "development" boards, without their own eeprom. There is a pretty easy to use patch, though, to let you load eeprom settings from a file and/or from the device tree - it might be fun for students to play with.
