Anyone, living in Europe, and available to donate an ETM throttle body send me a message to [email protected].
Now I have one for testing thank you ππ».
To run the Engine throttle control unit (ETM), 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's VIN number and with all other open hardware electronic components installed on a vehicle. In practical terms, this means, that 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 for 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 Blockchainβlike Fingerprint ID to a Data Repository".

This OHE is a direct fit and direct replacement of the factory hardware electronics found on Bosch ETMs. It has more complex electronics with CAN BUS connectivity. It uses 2 hall sensors that output a PWM analog +5V DC signal and it can be programmed using the CANBUS to match the sensor specifications of the vehicle where is going to be installed. This means is compatible with any open-source ECU such as Speeduino and many others.
3D rendering of the open hardware electronics for the Bosch ETM
This PCB is being sold fully assembled, and ready to be installed on the buyer's Volvo ETM. Mind you this electronics is not compatible with the Volvo factory electronics. It is compatible with open hardware solutions such as speeduino, the open ECU available on this project, and many other open ECUs. To order and buy send me a message on WhatsApp +32 471 632 520 and include the brand, model, and year of your Volvo. Thank you π.
π’ 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.
π― Fully tested & working, no improvements necessary - already being sold online
π Fully Open hardware \ source code
π€ͺ There's better than this. don't use it
π Fully closed hardware \ source code
β‘οΈ fully tested and working, however, it is a dangerous solution to deploy
π‘ 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.
π΄ 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.
β 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.
π New updated contents
The new icon means the link next to it was recently updated with new contents
π¬ Comments on the Discussion page
The comments icon means there are useful and even new comments on the discussions page of the repository important for what you are seeing or reading.
