These are surplus SM-S4303R standard-sized servos continuous rotation servos that we are able to offer at specially discounted pricing. They are functionally identical to our stock SM-S4303R servos except for the direction of rotation, which is reversed, and we are selling them in pairs to help differentiate them. This product is a two-pack of servos, so ordering one unit will get you two servos.

Key specs at 6 V: 54 RPM (no-load), 71 oz-in (5.1 kg-cm), 41 g, CW rotation for pulse widths above the rest point.

This sensor is a carrier/breakout board for the ST L3GD20 three-axis gyroscope, which measures the angular rates of rotation about the roll (X), pitch (Y), and yaw (Z) axes. Angular velocity measurements with a configurable range of ±250°/s, ±500°/s, or ±2000°/s can be read through a digital I²C or SPI interface. The board has a 3.3 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.5–5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

Clearance: This board is being replaced by the newer L3GD20H carrier and LSM6DS33 carrier.

Clearance: This is being replaced by a functionally identical version that has a removable protective end cap over the encoder.

This gearmotor consists of a low-power, 6 V brushed DC motor combined with a 226.76:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 10,884.47 counts per revolution of the gearbox’s output shaft. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox.

This 14 cm (5.5″) cable has two 26 AWG conductors with a 2mm-pitch 2-pin female JST PH-style connector. The other ends of the wires are unterminated; they can be cut to length to match your application. The red and black wires are twisted together to reduce noise.

Note: This cable has the red wire on pin 1 and black wire on pin 2, which differs from the color order convention followed by most of our other JST PH cables.
