About the CoolKidsBadge-2024 PCB

CoolKidsBadge-2024 is an open source ESP32 PCB design by tixlegeek, published on GitHub under the GPL-3.0 license. It is a board, with 74 components from 43 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the NRF24L01_SMD, AMS1117-3.3 and CH340C. By type, the board carries 14 capacitors, 12 test points, 9 resistors, 6 jumpers, 5 transistors and 4 ICs.

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

From the project

The CoolKid'sBadge is a convention electronic badge created for the LeHack2024 Cyber-security convention in Paris(Fr) (not affiliated), containing an ESP32S3 with 16Mb Flash, a NRF24L01 Slot, and a FlipperZero interface, and much more!

The CoolKid'sBadge is a convention electronic badge created for the LeHack2024 Cyber-security convention in Paris(Fr) (not affiliated), containing an ESP32S3 with 16Mb Flash, a NRF24L01 Slot, a FlipperZero interface, 7 LEDs and some pads. It can be powered directly from the GPIO Port of the FlipperZero, or via the USB C Connector.

This project started by 2023, but could not be ready in time for LeHack2023. So the project continued live on twitch at https://twitch.tv/tixlegeek

CoolKidsBadge-2024: common questions

What microcontroller does the CoolKidsBadge-2024 use?

The CoolKidsBadge-2024 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How many components are on the CoolKidsBadge-2024?

74 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the CoolKidsBadge-2024 design files?

From the tixlegeek/CoolKidsBadge-2024 repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the CoolKidsBadge-2024 design in my own project?

Yes, under the terms of its GPL-3.0 license, which tixlegeek chose for the repository.

Can I test firmware for the CoolKidsBadge-2024 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.
