Arduino Diecimila/ATmega168 microcontroller powers the system at 5V with a recommended input voltage range of 7-12V and a limit of 6-20V. It has 14 digital I/O pins, six of which offer PWM output, and six analog input pins. The board supplies 40mA per I/O pin and 50mA at the 3.3V pin. Its memory comprises 16KB (with 2KB used by the bootloader), 1KB of SRAM, and 512 bytes of EEPROM. The clock speed is 16MHz. Servo motors include the Hextronik HXT900 - 9g Micro Servo with an analog modulation, 4.8V torque of 22.2 oz-in (1.60 kg-cm), and a speed of 0.12 sec/60° at 4.8V. It weighs 0.32 ounces (9.1g) with dimensions of 0.83 inches (21.0mm) in length, 0.47 inches (12.0mm) in width, and 0.87 inches (22.0mm) in height. The motor is coreless, the gear type is plastic, and it has a bushing for rotation support. Additional specifications include a 90° rotational range, pulse cycle of 20ms, and a JR connector type. The Zebra ZS-S2113 Servo features an analog modulation with a torque of 4.8V at 38.9 oz-in (2.80 kg-cm) and 6.0V at 52.8 oz-in (3.80 kg-cm). It has a speed of 0.19 sec/60° at 4.8V and 0.14 sec/60° at 6.0V. With dimensions of 1.58 inches (40.0mm) in length, 0.79 inches (20.0mm) in width, and 1.44 inches (36.5mm) in height, it weighs 1.52 ounces (43.0g). The motor is skewed, the gear type is plastic, and it has a bushing for rotation support as well.
