Sensors2-pin digital temperature sensor (TO-92 case) from Texas Instruments
ActuatorsDual gearmotor made up of two independent motors and a set of gears. The ratios available are 12.7:1 – 38.2:1 – 114.7:1 and 344.2:1. A different ratio can be fitted on each side. Two hexagonal shafts, 50 mm long and 3 mm across, come out of the DGEARBOX and carry the robot wheels
Control electronicsThe MD25HV is a power driver with bidirectional control for 1 DC motor, with a supply between 7 VDC and 58 VDC. It can carry 25 A continuously without an additional heatsink. It has a terminal block for the motor and power connections, a 5 VDC output (max 250 mA) to power an external controller or other device, two test buttons that let you test the motor quickly and conveniently without connecting a controller, inputs for external control (PWM and DIR) and status LEDs for Power, Fault and Run.
Control electronicsCompact driver able to run 2 DC motors or one bipolar/unipolar stepper motor with a max supply voltage
Control electronicsCompact power driver able to run 2 DC motors with a supply voltage between 7 Vdc and 35 Vdc and a max. current
Control electronicsPaired with Arduino or another microcontroller, this compact driver lets you control the G15 Servo Cube
SensorsBreakout board based on the Maxim Dallas DS18B20 semiconductor temperature sensor (TSSOP version)
Control electronicsCompact power driver able to drive 2 DC motors with a supply voltage between 7 Vdc and 35 Vdc and a max
SensorsMade of stainless steel and fitted with two floats, one for the minimum level and one for the maximum level, this float switch is used to detect the level of a liquid inside a tank and can switch on a pump, a warning light, an alarm or another device
SensorsMade up of two optical encoders and two discs to be fitted on the motor shaft, this set measures speed, providing 20 counts per full revolution
SensorsBreakout board built around the Omron D7S, the smallest seismic sensor in the world. The D7S contains a three-axis accelerometer, of which only two axes are used while an earthquake is being detected; they can be selected by the user or automatically, according to how the sensor is tilted.
Control electronicsBased on the Allegro A3967SLB chip, this small driver can control a single bipolar stepper motor
STEMMade of wood and fitted with rubber tracks, this tank can drive over all sorts of surfaces. Ready to turn your free time into an adventure in building and play. Just add two batteries and the fun is guaranteed!
SensorsSet consisting of an interface board and a 20 kg load cell mounted inside a mechanical frame. The board is based on the HX711 chip, a 24-bit analogue-to-digital converter designed to connect the load cell to a microcontroller such as Arduino, Fishino or compatible boards
SensorsThe readings can be taken over the TTL interface, using Arduino (or another microcontroller) or a PC, through a serial-to-USB converter.
Control electronicsROBOPICO is the ideal expansion board for Raspberry Pi Pico and Pico W. With a DC motor controller, servo pins and Grove I/O ports, it is perfect for robotics and IoT projects. Compatible with CircuitPython, MicroPython, C/C++ and Arduino.
AccessoriesFemale-to-female cable for RC servos, about 70 cm long
SensorsSmall board able to detect the presence of a flame or a light source with a wavelength between 760 nm and 1100 nm
AccessoriesLightweight, sturdy flat bracket made from 3 mm blue anodised aluminium, with 21 holes (3 of 8 mm and 18 of 4 mm), for building mechanical structures for all kinds of applications
