Features and benefits PWM on 3 pins with software PWM expansion Provides direct PWM outputs on three pins, with software PWM available to extend control to additional outputs as needed. This helps you precisely dim LEDs, regulate motor speed, or control other actuators without extra hardware. Memory 2.8 k Memory (about 6 k after bootloader). This gives you room to run small programs and manage essential operations, with additional space freed after bootloader initialization. Visual indicators The Power LED and test LEDs give quick, ataglance status of power and functionality, aiding fast diagnostics during development and testing. I/O configuration IO available on 4 pins for basic input/output tasks, enabling simple interfacing with sensors, buttons, or small peripherals. Use cases LED dimming and color control Use the PWM outputs to smooth brightness transitions for indicators, status lights, or small RGB LEDs, achieving consistent lighting effects with minimal components. Small robotics and motion control Drive small DC motors or servos with PWM for smooth speed control and precise positioning in compact robotics projects. Sensor interfacing and signaling Use the 4 I/O pins to read button states, switches, or simple sensors, and drive corresponding indicators or signals in a compact, straightforward setup.
