Its main chip is the SSQ-122-03-G-S, from the ESP32 family. Other key parts include the TJA1055T/3/2Z, CLVC1G125QDBVRQ1 and TLS715B0EJV50XUMA1. By type, the board carries 15 resistors, 6 capacitors, 3 ICs, 2 connectors, 1 fuse and 1 jumper.

From the project

Safety-first embedded remote-control architecture for BMW E9x

Cette arborescence décrit la révision PCB Phase 3G. Elle ne remplace pas le prototype perfboard gelé dans hardware/kcan-rxonly/.

Le prototype Phase 3G est exclusivement destiné au banc. Il emploie un TJA1055T/3 pour observer un bus ISO 11898-3 à 100 kbit/s et conserve une coupure TX physique : la sortie U2.Y se termine sur TPGATEY; la broche U1.TXD est uniquement tirée au niveau récessif par RTXD. Il n'existe sur le PCB ni composant RLINKTX`, ni piste, ni via, ni zone reliant ces deux nets.

The KiCad project lives in the Synaro/BMW-E9x-Remote-Control repository on GitHub; these links point at the commit this page was built from.

BMW-E9x-Remote-Control: common questions

What microcontroller does the BMW-E9x-Remote-Control use?

The BMW-E9x-Remote-Control is built around the SSQ-122-03-G-S, from the ESP32 family.

How big is the BMW-E9x-Remote-Control PCB?

The BMW-E9x-Remote-Control measures 120 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BMW-E9x-Remote-Control?

31 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the BMW-E9x-Remote-Control design files?

From the Synaro/BMW-E9x-Remote-Control repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the BMW-E9x-Remote-Control design in my own project?

Yes, under the terms of its MIT license, which Synaro chose for the repository.

Can I test firmware for the BMW-E9x-Remote-Control without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
