About the OzSec2025 PCB

OzSec2025 is an open source RP2040/RP2350 PCB design by OzSecICT, published on GitHub. It is a 2-layer board measuring 88.6 × 92.6 mm, with 110 components from 35 distinct parts.

Its main chip is the RP2350_80QFN, from the RP2040/RP2350 family. Other key parts include the TLV1117LV-33, USBLC6-2SC6, ME4054BM5G-N and W25Q128JVS. By type, the board carries 34 resistors, 25 diodes, 22 capacitors, 11 switches, 5 ICs and 5 connectors.

It belongs with the wearables designs in this gallery.

From the project

This badge will be built in MicroPython on an RP2040 or RP2350, and support multiple minigames.

This badge will be built in MicroPython on an RP2040 or RP2350, and support multiple minigames.

This repo is currently a work in progress as we start planning how to lay out the badge firmware.

Install Python, and then install mpremote. Install VS Code, and clone this repository. Open the repo in VS Code and install the recommended extensions.

Currently the badge firmware is developed with a Raspberry Pi Pico 2 on a breadboard. If you want to see the code, obtain one and follow these steps to get it setup: - Plug in drive while holding BOOTSEL and use the flash script or VS Code Task to…

OzSec2025: common questions

What microcontroller does the OzSec2025 use?

The OzSec2025 is built around the RP2350_80QFN, from the RP2040/RP2350 family.

How big is the OzSec2025 PCB?

The OzSec2025 measures 88.6 × 92.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OzSec2025?

110 components, from 35 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 OzSec2025 design files?

From the OzSecICT/badge-crashandburn 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 OzSec2025 design in my own project?

The repository has no license, so all rights stay with OzSecICT. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the OzSec2025 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
