About the Blink PCB

Blink is an open source ESP32 PCB design by Rando1f, published on GitHub under the MIT license. It is a 2-layer board measuring 74.9 × 82.6 mm, with 5 components from 5 distinct parts.

Its main chip is the ESP32_30pin, from the ESP32 family. Other key parts include the HC-SR04. By type, the board carries 2 ICs, 2 resistors and 1 LED.

It belongs with the displays & leds designs in this gallery.

From the project

a partner in crime, helping you with

blink is plugged into the users device through a micro-usb port that has clearance of about 0.5 mm in the case and is mounted on the bottom of your desk after you screw the lid with body of the case either through superglue or a doubled face tape since blink is fairly light.

AI was only used for research purposes, and it wasn't used excessively. Rather, it was used as a resource-gathering tool so I could understand more of the project. The read.me is fully human-written, as well as the journal and the bill of materials.

Blink: common questions

What microcontroller does the Blink use?

The Blink is built around the ESP32_30pin, from the ESP32 family.

How big is the Blink PCB?

The Blink measures 74.9 × 82.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Blink?

5 components, from 5 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 Blink design files?

From the Rando1f/Blink 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 Blink design in my own project?

Yes, under the terms of its MIT license, which Rando1f chose for the repository.

Can I test firmware for the Blink 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.
