About the Doorman slot PCB

Doorman slot is an open source RP2040/RP2350 PCB design by AzonInc, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 23 × 32 mm, with 26 components from 16 distinct parts.

Its main chip is the ESP32-PICO-MINI-02, from the RP2040/RP2350 family. Other key parts include the XC6210B332MR. By type, the board carries 11 capacitors, 7 resistors, 2 ICs, 2 connectors, 2 diodes and 1 transistor.

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

From the project

ESP32-S3 based Intercom Gateway (TCS / Koch / Niko / Scantron / Analogue Systems)

Doorman S3 is a versatile intercom gateway designed to connect your TCS or Koch intercom system to any home automation platform. It's also compatible with rebranded versions of Niko, Scantron, and older Jung intercom models.

But that's not all - the Doorman S3 is more than just an intercom bridge. With its integrated relay, you can simulate button presses to control door openers or lights, supporting up to 40V and a maximum of 2.5A.

Doorman slot: common questions

What microcontroller does the Doorman slot use?

The Doorman slot is built around the ESP32-PICO-MINI-02, from the RP2040/RP2350 family.

How big is the Doorman slot PCB?

The Doorman slot measures 23 × 32 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Doorman slot?

26 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Doorman slot design files?

From the AzonInc/Doorman repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Doorman slot design in my own project?

Yes, under the terms of its GPL-3.0 license, which AzonInc chose for the repository.

Can I test firmware for the Doorman slot without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
