[hackerspaces] Advice on finding specs for bluetooth module

[Charles Paul]

Aloha everyone,

I am trying to find the specs for Airoha AB1108 Bluetooth keyboard
modules.  There are several cheap mini keyboards on the market which
use this controller; I am hoping that this (or another low-cost
module) could be an affordable platform for creating custom wireless
human interface devices.

Does anybody have advice for soliciting technical docs from
manufacturers or distributors?

Take Care,
