HM-11 BLE Bluetooth Module
These BLE modules are a really simple to use module. We put a landing for them on our Brains Board for the kickstarter but haven't got around to doing anything with them. We have some left over and want to move the stock on in our clearance sale! When they're gone they're gone! Which is now.
(image shows soldered they come unsoldered and without Brains Board).
