About the FIDO2-Custom-RP2354A-Hardware-Security-Key with male-USB-C PCB

FIDO2-Custom-RP2354A-Hardware-Security-Key with male-USB-C is an open source Raspberry Pi PCB design by jtausif568, published on GitHub. It is a 2-layer board measuring 49.9 × 20 mm, with 28 components from 17 distinct parts.

Its main chip is the RP2354A, from the Raspberry Pi family. Other key parts include the USBLC6-2SC6, TYPEC-950-ARP24 and AP2112K-3.3. By type, the board carries 10 capacitors, 9 resistors, 4 ICs, 2 switches, 1 crystal and 1 diode.

From the project

A custom hardware security key with plug-in USB-C based on the RP2354A to skip annoying multi-layered authentication

A from-scratch, keychain-sized FIDO2/WebAuthn hardware security key built on the Raspberry Pi RP2354A, intended to run a fork of the open-source pico-fido firmware. The board integrates a male USB-C plug so the finished device plugs directly into a host like a USB stick - no cable - for passwordless multi-factor authentication.

This repository contains the complete KiCad hardware design (schematic + PCB layout). The hardware design is complete - schematic captured, board fully routed, and DRC/ERC clean.
