The following list details the major changes:
Two USB OTG LEDs: LD5 (green) VBUS and LD6 (red) OC (over-current)
Many I/O lines in a small package 15 general-purpose I/O pins available along the sides of the board
allowing this version to power servos and other high-power peripherals for which the battery voltage would be too high

Schrittmotor: bipolar, 200 Schritte/Umdrehung, 35 x 26 mm, 7,4 V, 280 mA Abverkaufen The following list details theThis hybrid bipolar stepper motor has a step angle of 1. 8 (200 steps revolution). Each phase draws 280 mA at 7. 4 V, providing a holding torque of 650 g cm (9 oz in). The motor has four color coded wires with bare leads: black and green connect to one coil, and red and blue to the other. It can be controlled via a pair of suitable H bridges (one for each coil), but we recommend using a bipolar stepper motor driver. A 5 mm universal mounting hub
