From the project

Diseño electrónico en KiCad 10 para un sistema de acceso escolar basado en ESP32, RC522, sensores y control de cerradura de 12 V.

Diseño electrónico en KiCad 10 para un sistema de acceso escolar basado en ESP32, RC522, sensores y control de cerradura de 12 V.

Hay una placa de prueba de 140 × 100 mm, doble cara, ruteada y con el DRC limpio: 348 pistas, 8 vías, dos planos de masa separados que se tocan en un solo punto, y ninguna infracción de margen, cobre, alivio térmico ni serigrafía. Los tres "no conectados" que informa el DRC son deliberados.

Rfid eest3: common questions

What microcontroller does the Rfid eest3 use?

The Rfid eest3 is built around the ESP32-S3-DevKitC-1_N16R8_44P, from the ESP32 family.

How big is the Rfid eest3 PCB?

The Rfid eest3 measures 140 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rfid eest3?

66 components, from 47 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rfid eest3 design files?

From the resourceldg/rfid-eest3-kicad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rfid eest3 design in my own project?

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

Can I test firmware for the Rfid eest3 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.
