  To run the Instruments Cluster, 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, 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 Blockchain‐like Fingerprint ID to a Data Repository".

OEM Connectors
The factory original connector is from JAE Electronics reference IL-AG5-14P-D3T2. Sold on Digikey here.

Component requiements:

• IL-AG5-14S-D3C1-A sold on DigiKey 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 🙏.

To retrofit an R Style Instruments Cluster with the blue dial gauges you will need:

• 4x R-style blue gauge dials
• 4x M3 Standoff Spacers with 12mm height sold on AliExpress (see here) (models up to 2004)
• The 4x LED retro Illumination add-ons below (models up to 2004)

^{(models up to 2004)}

PCBs made to fit each gauge in the instrument cluster for LED retro illumination.

• Fuel Gauge LED retro illumination
• Temperature Gauge LED retro illumination
• Engine RPM Gauge LED retro illumination
• Speed Gauge LED retro illumination

To read detailed instructions in tutorial format go to Hackster.IO (soon!). Alternatively on Swedespeed.com for models from 2005 and above.

The gauge dials are being sold as a kit, meaning, the buyer will have to do soldering and component assembly, and there's also the option of fully assembled and ready to be installed on the buyer's dashboard dials. Don't forget to view the LED add-on for the rear back doors.

To order and buy, go to my store on Tindie.com.
For technical support during installation send me a message on WhatsApp +32 471 632 520. Thank you 🙏.

To replace the factory Volvo Instruments Cluster with the OPEN Instruments Cluster you will need:

• The OPEN Instruments Cluster Hardware electronics (soon!)

To read detailed instructions in tutorial format go to Hackster.IO (soon!).

• Engine RPM Gauge
• Speed RPM Gauge
