Led blinker
About the Led blinker PCB
Led blinker is an open source ESP32 PCB design by AlAminAshik, published on GitHub. It is a 2-layer board measuring 37 × 49.3 mm, with 16 components from 10 distinct parts.
Its main chip is the ESP32-WROOM-32, from the ESP32 family. By type, the board carries 7 connectors, 4 diodes, 3 resistors, 1 IC and 1 capacitor.

Led blinker: common questions
What microcontroller does the Led blinker use?
The Led blinker is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the Led blinker PCB?
The Led blinker measures 37 × 49.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Led blinker?
16 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Led blinker design files?
From the AlAminAshik/KiCAD_PCB_DesignTool_myResources repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Led blinker design in my own project?
The repository has no license, so all rights stay with AlAminAshik. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Led blinker 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.
