About the Practice PCB

Practice is an open source ESP32 PCB design by wlatif-cmyk, published on GitHub. It is a 2-layer board measuring 77.5 × 106 mm, with 7 components from 7 distinct parts.

Its main chip is the ESP32-S2-WROVER, from the ESP32 family. Other key parts include the AM2302. By type, the board carries 2 ICs, 2 capacitors, 1 switch and 1 resistor.

It belongs with the sensors, iot & wireless and displays & leds designs in this gallery.

Every day, I build something small, fun, or weird — and post it on TikTok.

This repo collects the code, notes, and mini-projects from each day.

Follow along as this slowly turns into a chaotic but glorious archive of experiments.

Practice: common questions

What microcontroller does the Practice use?

The Practice is built around the ESP32-S2-WROVER, from the ESP32 family.

How big is the Practice PCB?

The Practice measures 77.5 × 106 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Practice?

7 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Practice design files?

From the wlatif-cmyk/100daysofprojects repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Practice design in my own project?

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

Can I test firmware for the Practice 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.
