About the PCB-Business-Card

PCB-Business-Card is an open source ESP32 PCB design by Studented0, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 75 mm, with 20 components from 13 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the AMS1117-3.3 and NT3H2111W0FHKH. By type, the board carries 7 resistors, 6 capacitors, 3 ICs, 2 switches and 1 connector.

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

From the project

A PCB business card with a little twist (A display and ESP32 to connect to lanyard and display spotify music and NFC)

PCB Business Card-bom.csv # PCB-Business-Card

A PCB Business card that shows your Spotify activity using lanyard in real time. Tap the card with a phone to show what song is playing on Spotify.

Powered over USB-C from a phone or any power bank. Connects to a phone hotspot (or any wifi) for the Lanyard WebSocket.

I wanted a business card that has a cool twist. Plain cards feel boring to show and they are all the same. This one shows what I'm listening to, lets someone tap it to hear the same song, and has my GitHub a QR scan away. Business cards are supposed to grab people's attention, and…

PCB-Business-Card: common questions

What microcontroller does the PCB-Business-Card use?

The PCB-Business-Card is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the PCB-Business-Card?

The PCB-Business-Card measures 100 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB-Business-Card?

20 components, from 13 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 PCB-Business-Card design files?

From the Studented0/PCB-Business-Card 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 PCB-Business-Card design in my own project?

Yes, under the terms of its MIT license, which Studented0 chose for the repository.

Can I test firmware for the PCB-Business-Card 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.
