The two power wires are brought out separately to make wiring easier

The final orange wire is what controls the buzzer which will sound continuously when the wire is grounded

but it allows to have multiple receivers

We have a generic photo showing how the module sticks to the back of our Android phone

Using this programmer and avrdude you can program any in-circuit "serial" programmable chip that avrdude supports (which is nearly all of them)

Beetle BLE Brand_FriedCircuits The two power wires areThe Beetle Ble (Former name Bluno Beetle) is a board based on Arduino Uno with Bluetooth 4. 0 (BLE). It is probably the smallest BLE board in the market! It uses standard Arduino IDE to upload codes via without any extra library and drivers. This Beetle BLE is another milestone in the Beetle line, which makes DIY users have more options in the project design. It is fully compatible with Bluno in instructions and procedures.
