Nitrokey 3A NFC Hacker
NOT A READY-TO-USE SECURITY KEY. This is the bare Nitrokey 3A NFC electronics shipped WITHOUT firmware, in an unprinted case, for developers building their own firmware on the LPC55S69. If you want a working key, buy the Nitrokey 3A NFC instead.

Why the Nitrokey 3A NFC Hacker
What this developer board does that alternatives don't.
Ships without firmware, on purpose
The MCU is freely programmable and arrives blank. Nothing works out of the box — no FIDO2, no OpenPGP — until you flash your own build.
Real Nitrokey 3A NFC hardware
Same NXP LPC55S69JEV98, NFC antenna and touch sensor as the shipping key, so firmware you develop here behaves as it will on production hardware.
Debugging needs extra hardware
Nitrokey recommends an LPC-Link2 for debugging; it is NOT included. An MCU-Link may work but is untested by the vendor.
Specifications
Full technical details.
Compliance framework mapping
Controls this product satisfies across 12 frameworks.
Multi-factor authentication — hardware-bound
Phishing-resistant MFA using hardware security keys. Software TOTP and SMS are explicitly excluded from "phishing-resistant" in NIST 800-63B and most modern framework guidance.
Cryptographic key management
Hardware-bound key generation and storage. Private keys generated and stored inside a certified secure element (EAL 6+) and are non-exportable by design — for login credentials (Nitrokey) and crypto-asset custody (Ledger) alike.
Supply chain risk — hardware and firmware
Open-source firmware is publicly auditable and reproducibly built. EU jurisdiction hardware is not subject to US National Security Letters. Directly addresses hardware supply chain risk in CMMC and NIS2.
Compared to
Honest comparisons against the most likely alternatives.
vs. Nitrokey 3A NFC
Identical electronics. The shipping key arrives with signed Rust firmware, a printed case, and works immediately; this one does nothing until you write firmware for it.
