To run the Climate Control Module 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.
In regards to safety against theft the electronics will include a cryptographic IC that will be used to match the car owner 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 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 Blockchainโlike Fingerprint ID to a Data Repository".
OEM Connectors
Since all wiring connectors are proprietary of Volvo, is impossible to buy one one connector to solder and do pcb assembly. Nowadays there are a plethora of automotive OEM connectors sold on the internet, what is important is the connector to fit the existing Volvo enclosure housing for a particular electronics.
I've selected an OEM connector for this open climate control electronics being designed and prototyped. This connector is sold on AliExpress here.
Open Hardware Electronics
The KiCad footprint for this open hardware electronics can be found here. This footprint was carefully measured and It has the exact measurements and dimensions as the ones found on models from 2000 and 2004. If you like it and use it on your own hardware designs please support this project, click here to learn how. Thank you ๐.
PCB components
๐ข Fully tested and working
A green circle means the hardware electronics or the programming code was fully tested, each of its functionalities and capabilities. And it can be installed in a vehicle. Keep in mind this does not mean errors won't happen. As in everything related to electronics and software, there are revisions and updates. This open hardware is no different.
๐ฏ Fully tested & working, no improvements necessary - already being sold online
๐ Fully Open hardware \ source code
๐คช There's better than this. don't use it
๐ Fully closed hardware \ source code
โก๏ธ fully tested and working, however, it is a dangerous solution to deploy
๐ก Not tested. Working capability is unknown, it may work or not.
A yellow circle means the hardware electronics or the programming code was not fully tested, each of its functionalities and capabilities. This does not mean it not working, it simply means testing is needed before giving a green circle of approval.
๐ด Fully tested but not working.
A red circle means the hardware electronics or the programming code was fully tested, and found some kind of critical error or fault. This means the electronics or firmware code cannot be used in a vehicle.
โ Not started.
The hourglass means the hardware electronics or the programming hasn't started. Most likely because is waiting for the necessary test components needed for reverse engineering and also engineering of the new open solution.
