Disaggregated architecture
Functions run in separate chips, which prevents hidden/undocumented interactions within a chip.
MCU communicates through standard spi and i2c.
Examples of applications
Source code is opensource, concise and readable. You may adapt it to your own need.
Network diode
Use the MM-2350 as a simple yet trustable network diode.
- No configuration: just switch on
- Only udp frames from left to right are accepted
- Count blocked packets
Security module
Use the MM-2350 as a simple yet trustable Security module.
- Sign, verify, encrypt, decrypt, Diffie-Hellman
- Key types: RSA, EC, ED25519, X25519, AES, DES
- Access: http(s), ssh, console
- Authentication: tls certificate, ssh certificate, password
Case
Use 3D Slash to modelize and 3d print your case.
