About the 4F5LCD PCB

4F5LCD is an open source ESP32 PCB design by Code99it, published on GitHub under the MIT license. It is a 2-layer board measuring 155 × 78 mm, with 49 components from 18 distinct parts.

Its main chip is the ESP32-S3-DEVKITC-1U-N8R2, from the ESP32 family. Other key parts include the TLS850C2TEV33, MCP2515 and SN65HVD230. By type, the board carries 25 capacitors, 12 ICs, 5 crystals, 3 connectors, 2 diodes and 1 fuse.

Dieses Projekt ersetzt bei Fahrzeugen der VAG-Gruppe mit Plattform 4F (C6) das kleine Display in der Mitte des Kombiinstruments durch eine spezielle Mikrocontroller-Lösung. Die Bedienung erfolgt über die linken Tasten am Lenkrad: - Drehen am Rad wählt einen Listeneintrag. - Klicken auf das Drehrad aktiviert den gewählten Eintrag. - Die MODE-Taste am Lenkrad wechselt zwischen den Menüseiten. - Die Auf-Ab-Taste am Wischerhebel und die Bestätigungstaste auf der Hebel-Unterseite sind zunächst wirkungslos, die Funktion wird ggf. in späteren Projektversionen noch einmal aufgegriffen.

4F5LCD: common questions

What microcontroller does the 4F5LCD use?

The 4F5LCD is built around the ESP32-S3-DEVKITC-1U-N8R2, from the ESP32 family.

How big is the 4F5LCD PCB?

The 4F5LCD measures 155 × 78 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 4F5LCD?

49 components, from 18 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 4F5LCD design files?

From the Code99it/4F5LCD 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 4F5LCD design in my own project?

Yes, under the terms of its MIT license, which Code99it chose for the repository.

Can I test firmware for the 4F5LCD 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.
