About the PCB3 Contoller PCB

PCB3 Contoller is an open source ESP32 PCB design by ahaimour2005, published on GitHub under the MIT license. It is a 2-layer board measuring 35 × 70 mm, with 8 components from 7 distinct parts.

Its main chip is the Arduino Nano ESP32, from the ESP32 family. Other key parts include the 74AHCT125. By type, the board carries 4 connectors, 2 capacitors, 1 IC and 1 module.

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

From the project

MEDI is an interactive museum exhibit: a model human body where visitors press a button on a "pod" and the matching organ lights up. This repository holds everything for it: the firmware, the custom PCBs, the heart-rate sensor work that started the project, and the notes and data

MEDI is an interactive museum exhibit: a model human body where visitors press a button on a "pod" and the matching organ lights up. This repository holds everything for it: the firmware, the custom PCBs, the heart-rate sensor work that started the project, and the notes and datasheets behind them.

- Pods are wireless button boards placed around the room. One pod per organ (11 pods). - The conductor listens for pod presses and sends state commands (IDLE, HIGHLIGHT, PULSE, BLACKOUT) down a one-way wired bus. - Organ nodes each drive their own LED strip (NeoPixel) and own their animation…

PCB3 Contoller: common questions

What microcontroller does the PCB3 Contoller use?

The PCB3 Contoller is built around the Arduino Nano ESP32, from the ESP32 family.

How big is the PCB3 Contoller PCB?

The PCB3 Contoller measures 35 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB3 Contoller?

8 components, from 7 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 PCB3 Contoller design files?

From the ahaimour2005/BSF_Engineering_Better_Health-Medi_Development 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 PCB3 Contoller design in my own project?

Yes, under the terms of its MIT license, which ahaimour2005 chose for the repository.

Can I test firmware for the PCB3 Contoller 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.
