From the project

Custom PCB projects designed in KiCad featuring ESP32 and embedded systems.

A compact environmental monitoring and system display PCB built around the Arduino Nano ESP32. The board integrates a 0.91-inch I²C OLED display and a Bosch BME280 environmental sensor for measuring temperature, humidity, and atmospheric pressure. Designed in KiCad with an emphasis on clean routing, dual-layer ground planes, reliable I²C communication, and successful ERC/DRC verification.

ESP32 OLED Weather Display: common questions

What microcontroller does the ESP32 OLED Weather Display use?

The ESP32 OLED Weather Display is built around the Arduino_Nano_ESP32, from the AVR/Arduino family.

How big is the ESP32 OLED Weather Display PCB?

The ESP32 OLED Weather Display measures 50 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 OLED Weather Display?

14 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 OLED Weather Display design files?

From the motiforge-labs/PCB-Design-Portfolio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32 OLED Weather Display design in my own project?

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

Can I test firmware for the ESP32 OLED Weather Display without the hardware?

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