Secure DIY Garage Door Opener

Contributors: QCPete

Hardware Overview

For this project, we need to build up two separate circuits. One will be the remote control (that lives in my car or bike), and the second will be the base transceiver that lives inside my garage (listening for the ECC signature, and then engaging the garage door button).

Remote Control

• Pro RF
• Duck Antennae
• Cryptographic Co-processor (for creating the ECC signature)
• Enclosure
• Button
• 400mAh Lipo Battery
• Qwiic Cable (QTY:1)

Base Transceiver

• Pro RF
• Wire antennae
• Cryptographic Co-processor (for creating the TTL token, and verifying the ECC signature)
• SparkFun Qwiic Single Relay
• Wire antennae
• USB wall wart
• Qwiic Cable (QTY:2)

For easy one click ordering, here is a wish list. Be sure to read the entire tutorial, and then adjust as necessary.
