About the Zamkonator PCB

Zamkonator is an open source ESP32 PCB design by alufers, published on GitHub. It is a 2-layer board measuring 75.1 × 100 mm, with 149 components from 78 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the TCA9555RGER, RTL8201F, SI3404-A-GM, EL3H7-G and AN431. By type, the board carries 48 resistors, 41 capacitors, 20 diodes, 15 ICs, 11 connectors and 6 inductors.

From the project

RFID access-control board with PoE and Wiegand

INFO: This project is in a work in progress state and is not yet complete.

This is a repository for the hardware and software for a PoE powered locks system. It reads RFID cards using the Wiegand interface, and opens an electronic door latch to grant entry. This project simplifies the deployment of such systems by eliminating the need for a separate power supply for the lock. Additionally it connects directly to a LDAP server to authenticate users, thus removing any central coordination between multiple locks.

Zamkonator: common questions

What microcontroller does the Zamkonator use?

The Zamkonator is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Zamkonator PCB?

The Zamkonator measures 75.1 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Zamkonator?

149 components, from 78 distinct parts. The full bill of materials is listed on this page.

Where can I download the Zamkonator design files?

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

Can I use the Zamkonator design in my own project?

The repository has no license, so all rights stay with alufers. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Zamkonator 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.
