- 2X Voltage & Auto-Protection: 6-50V Ultra-Wide Input. Built-in self-recovery fuse prevents burnout from wiring errors, while dual voltage regulation (DC-DC LDO) ensures stable 5V output even with unstable sources.
- Dual Voltage & Easy Updates: 3.3V/5V Switch BOOT Button. Adapt to 3.3V/5V sensors (vs. fixed 5V on classic UNO) without level shifters. One-click firmware upgrades via BOOT button eliminate debug tools.
- Full Arduino UNO R4 Compatibility: Directly reuse UNO R4 shields and libraries. Dual connectivity (male headers female sockets) fits personal projects and industrial modules, while the 2.54mm SWD port (vs. 1.27mm on official R4) works with standard debug cables.
- Pro-Level Peripherals Built-In: 12-bit DAC, CAN Bus & HID Support – Drive industrial actuators (PLCs, LED arrays) via 24V inputs or simulate keyboards/mice through USB-C. All without extra modules – ideal for IoT hubs or robotics projects.
- UNO R4 Performance with Enhanced Power: 48MHz Cortex-M4 – Match R4 Minima’s 256KB Flash for complex tasks (solar/ML), but with 50V input flexibility (vs. R4's 24V) for extreme environments.
