The UNO R3 PRO upgrades to a robust USB Type-C port and integrates a high-efficiency 5V/2.5A (12.5W) power module. This massive power headroom allows users to drive multiple high-torque servos, toy motors, and advanced micro-slides directly without an external shield. Additionally, it features an on-board dedicated lithium battery port (supporting 14500/18650 batteries), which is good choice for untethered mobile robots, advanced STEM education, and complex IoT prototyping.
