Hardware Hookup
All of these boards use Qwiic, so that made things much easier and faster to hookup.
The Remote
For the remote control, there are only 4 connections that need to be made:
| From/Device 1 | Connection Type | To/Device 2 | |
| 1. | Pro RF | Qwiic Cable | Cryptographic Co-processor |
| 2. | LiPo Battery | JST | Pro RF |
| 3. | Duck Antennae | U.FL to SMA adapter cable | Pro RF |
| 4. | Button | Wire | Switch Headers on Pro RF |
The remote control all wired up.
The Base Transceiver
The Base Transceiver also requires hooking up just 4 connections:
| From/Device 1 | Connection Type | To/Device 2 | |
| 1. | Power adapter | USB | Pro RF |
| 2. | Pro RF | Qwiic Cable | Cryptographic Co-processor |
| 3. | Cryptographic Co-processor | Qwiic Cable | Relay |
| 4. | Relay COM & NO | Wire | Garage door button |
Note, the order of boards in the qwiic system didn't matter, but I put the relay last so I could position it for easier access. I also soldered to the PTH pins on the bottom of the screw pin terminal, but you could choose to do a solderless connection if you like.
The Base Transceiver all wired up.
