Its main chip is the ESP32-WROOM-32E-N16, from the ESP32 family. Other key parts include the W5500, CH340C and MP2307DN-HW-LF-Z. By type, the board carries 19 capacitors, 18 resistors, 7 connectors, 5 ICs, 5 diodes and 3 transistors.

From the project

PCB design and ESP32 firmware for Portero Bot gate controller (Claustro4)

Custom PCB and ESP32 firmware for the Claustro4 gate controller system.

Replaces the Raspberry Pi Pico + protoboard + commercial relay board with a professional custom PCB.

- MCU: ESP32-WROOM-32E - Ethernet: W5500 (SPI) + HanRun HR911105A RJ45 - Relays: 3× dry contact (simulates button press on gate opener controllers) - Power: 9-24V DC barrel jack → 5V buck → 3.3V LDO - Programming: MicroUSB (first flash) + OTA over Ethernet (updates)

Portero bot hardware: common questions

What microcontroller does the Portero bot hardware use?

The Portero bot hardware is built around the ESP32-WROOM-32E-N16, from the ESP32 family.

How big is the Portero bot hardware PCB?

The Portero bot hardware measures 117.5 × 104.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Portero bot hardware?

71 components, from 34 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 Portero bot hardware design files?

From the Willis75/portero-bot-hardware 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 Portero bot hardware design in my own project?

The repository has no license, so all rights stay with Willis75. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Portero bot hardware 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.
