OAE can be mounted on either a EQ5 style or a sturdy Arcaswiss Tripod. EQ5 style tripods can commonly be found as steel or aluminum options, where the steel version is sturdier but also heavier. The aluminum option can be cheaper and more portable, while still being sturdy enough for OAE.
Arcaswiss tripods exist in a lot of variations. Cheaper ones are commonly too wobbly for astronomy, so if you go this route get one with a high payload.
OAE uses barbell plates as counterweights, as they are cheaper and more available than the special astronomy alternatives. Supported center hole diameters are 28mm (Decathlon), 32mm and 2 inch (US Olympic).
You will need slightly less weight as your imaging gear weighs. For example, my telescope + camera + guider weighs 3.5kg, and 3kg of counterweights are needed for balance.
OAE is supplied through the barrel jack on its side. You will need a power supply with a 5.5x2.1mm jack, and 12V at at least 2A.
OAE currently only supports attaching your camera/telescope with an arcaswiss clamp. A arcaswiss plate is included in the kits. Vixen style telescope will not fit unless adapted to arcaswiss.
OAE requires a computer to control, it does not have a standalone controller like OAT does. Ideally a windows machine is used, as the support is best there. Linux is somewhat supported but lacks all the features (like autoPA), and is rather untested. Mac is not supported.
