  • 5V or 3.3V supply with on-board power management, USB VBUS detection and low power mode for use with battery-powered devices

  • USB and serial UART, SPI and I2C interfaces via castellated SMD pinout. Developer/evaluation kit available Q3 2025.

  • MIFARE & NFC tag support including UID, MIFARE sector, secure DESFire, Ultralight AES, NDEF, HCE and MIFARE2Go

  • Support for up to 255 external serial RGB LEDs including animation

  • Configuration, keys and firmware updates managed locally over USB or serial

  • Powerful real and virtual COM interface with multiple protocols including secure OSDP over serial, SPI and I2C

  • Secure on-board decryption of many pass types and storage of multiple ECC and AES keys

  • Additional NFC tag emulation and GymKit handoff modes

  • On board EAL6+ secure element (SE050) plus other additional I/O pins and features available
