SSC-32U USB 32 Servo Controller Atmega 328P

The SSC-32U is a powerful and versatile USB servo controller based on the Atmel ATmega328P microcontroller. It allows you to control up to 32 independent servos via a serial interface (USB, TTL UART, or 3.3V XBee). It is ideal for mobile robots, robotic arms, or any project requiring complex and synchronized movement.

This board features an internal sequencer capable of managing predefined movements, such as the alternating gait of a tripod or the locomotion of a hexapod. It includes external EEPROM memory (512 kbit) to store programs and settings. The power management is optimized with automatic selection between logic and motor voltages, along with high-capacity capacitors to prevent voltage drops during current spikes.
