This version of the FS5106B standard servo from FEETECH is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, allowing you to directly measure the position of the output. This extra information enables more complex robotics applications, such as determining when the servo has reached its target, detecting when the output is blocked, or implementing your own higher-level closed-loop position control.

The RoboClaw Solo motor controllers from Basicmicro (formerly Ion Motion Control) can control a single brushed DC motor using USB serial, TTL serial, RC, or analog inputs. An integrated quadrature decoder makes it easy to create a closed-loop speed control system. It features an all-metal case and four screw terminals (two for power and two for the motor). This version can supply a continuous 300 A and operates up to 60 V.

This UL-listed “wall wart”-style switching power adapter supplies up to 2.5 A at a regulated 5.15 VDC. It is intended for use with 5V USB devices, and it has been specifically designed to supply slightly more than 5 V to help ensure that the device it is powering receives close to 5 V even when the current draw is high. The AC adapter works with input voltages of 100-240 VAC and has a 1.5 m (5 ft) DC power cord that is terminated by a USB micro-B connector.

This small NEMA 8-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 800 mA at 4.3 V, allowing for a holding torque of 300 g-cm (4.2 oz-in). With a weight of 80 g, this is one of the smaller stepper motors we carry.

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.

This powerful synchronous switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.8 V and 22 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The board measures 0.9″ × 0.9″, has a typical efficiency of 85% to 95%, and can supply typical continuous output currents between 2 A and 4 A depending on the input voltage. The regulator also features reverse voltage protection and an optional enable input that can be used to put the regulator in a low-power state with a current draw of less than 10 µA per volt on VIN.

This small lidar-based distance sensor reports the distance of objects up to about 300 cm (120″) away with a pulsed signal similar to a hobby servo control signal. A digital microcontroller pin can be used to time the length of each high pulse, which encodes the measured distance. The sensor works over an input voltage range of 3.0 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

Note: The maximum range of 300 cm is only achievable for high-reflectance objects in good ambient conditions. Lower-reflectivity targets or poor ambient conditions will reduce the maximum range.
