Looks like the (relevant part of the) list is:

Core AW2041 = A20 SoC / 1gb RAM module

Core AW2042 = A20 SoC / 2gb RAM module

Core EVB = carrier board

They've also got a case and a "build your own" sort of kit thing where you can pick AW2041/AW2042, EVB (or not), case (or not), and power supply (US/EU 9v/12v... or not).

Looks like the power supply connector is the timeless 5.5mm/2.5mm barrel jack. Pretty common stuff.

I notice one intriguing thing on the wiki page Henrik posted -- on the underside of the EVB board, as shown in the dimensional drawing they have (it's the image on the right, under "hardware", if it's not obvious) -- there's a four-pin something with a PCB antenna -- internal USB WiFi or bluetooth adapter, maybe? The antenna layout (if it's accurate) would be about right for the BLE adapters on eBay, as is the size of the module. But I could see integrated WiFi a lot more easily.

Interesting, in any case...

I thought there was a second unmentioned item -- but it's labeled properly and I'd just missed that somehow, lol. It's an FFC/FPC connector for LCDs. 40 pins. It's also on the bottom of the board, right in the middle.
