I received a Beepy with a plain US keyboard but uneven keyboard backlighting. When I ordered a new Q10 keyboard from AliExpress, I got one that was left half Arabic/English and right half US-English. My T-deck came with the Arabic one. Seems like there are a lot of Arabic parts out there.
The Beepy is just as capable. The T-Deck is only serving as an interface to the Meshtastic LoRa node. A Beepy can run a Meshtastic companion app and connect over Bluetooth, just like the T-Deck.
Beepys have a pretty big issue with randomly shorting out due to a design flaw, according to the Discord forum anecdata. It happened to mine, unfortunately.
A very capable little device before it cooked itself, though—having a raspberry pi in your pocket is a lot of fun.
It is weird how the moment I saw the words 'mini keyboard' in the title I knew the exact keyboard module they were using, because it's the one everyone uses.
