  To run the rearview mirror electronics I'll be using EspressIF Systems ESP32 C3 microcontroller a single core Xtensa LX7 Core Processor running at 160MHz with 400Kb RAM. This MCU has wireless radio capabilities that are disabled on the hardware electronics itself for safety concerns. Instead, the hardware includes an extra chip for wireless connectivity with a key fob or a mobile app on a smartphone.

  In regards to safety against theft the electronics will include a cryptographic IC that will be used to match the car owner's VIN number and with all other open hardware electronic components installed on a vehicle. In practical terms this means, in the event of theft, to make a specific open hardware work on another vehicle, it will require the replacement of the main microcontroller processing unit without the need of specialized tools and equipment. More information about safety and sensor data validation on this sci. research paper titled "Validation of Experimental Data Origins: A Swarm of DAQ devices able to Deliver Unique Experimental Data using Blockchain‐like Fingerprint ID to a Data Repository".

If you like this project and want faster development, prototyping, and testing consider a donation or sponsoring the project. Alternatively, one can buy and donate a rearview mirror to help and speed up the design of new open hardware electronics, prototype, and testing. Send me an email to [email protected] to know more. Include in the subject "open electronics for Volvo p2". Thank you 🙏.
