About the Citofono vintage PCB

Citofono vintage is an open source ESP32 PCB design by michele88pg, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 81 × 85 mm, with 61 components from 46 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R2, from the ESP32 family. Other key parts include the LM5164DDA and AMS1117-3.3. By type, the board carries 18 resistors, 14 capacitors, 10 connectors, 7 diodes, 3 ICs and 2 relays.

It belongs with the iot & wireless and retro computing designs in this gallery.

From the project

Scheda open hardware ESP32-S3 che trasforma un telefono a disco d'epoca in citofono smart: apri con il disco, notifiche e apertura remota via ESPHome/Home Assistant. Compatibile con Siemens/Italtel S62 da parete e citofoni URMET 4+N.

Il progetto è stato sviluppato con KiCad 10, che apre anche i file dei formati precedenti. Tutti i simboli e i footprint vengono dalle librerie ufficiali di KiCad e sono incorporati nei file, quindi non servono librerie esterne.

Minimi: pista 0,2 mm, via 0,5/0,2 mm, distanza dal bordo 0,2 mm. Sono tutti entro le capacità standard di JLCPCB.

Zone: - GNDplane: sullo strato inferiore, solo nella zona logica. La massa è anche sbrogliata con piste, quindi il piano non è l'unico collegamento. - isolamento1…6: le strisce della barriera. Sono vietati piste, via e rame; pad e componenti sono…

Citofono vintage: common questions

What microcontroller does the Citofono vintage use?

The Citofono vintage is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.

How big is the Citofono vintage PCB?

The Citofono vintage measures 81 × 85 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Citofono vintage?

61 components, from 46 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 Citofono vintage design files?

From the michele88pg/citofono-vintage 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 Citofono vintage design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which michele88pg chose for the repository.

Can I test firmware for the Citofono vintage 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.
