USB Voltmeter Kit
USB Voltmeter is a PC based dual channel voltmeter built around PIC18F2550 microcontroller that measures voltage from 0.00V up to 500.00V with 10mV resolution. USB Voltmeter sends measured data to PC via standard USB connection displaying data on a computer monitor. USB Voltmeter is self-powered drawing very little current from USB port. Voltage readings are displayed via included USB Voltmeter software.

USB Thermometer Kit with Data Logger
USB Thermometer allows to measure temperature in two different locations. Two Microchip MCP9700 temperature sensors in standard TO-92 package are used to sample temperature and allow to measure temperature from -40 to +125 Celsius degrees. Simply connect to a PC computer via standard USB cable and temperature readings will be displayed using included USB Thermometer software. USB Thermometer takes power directly from USB port and does not need external power supply. Temperature readings can be displayed in both Fahrenheit and Celsius degrees.
USB Thermometer software comes with Data Logger feature. Date, time and temperature readings are saved to a text file and can be used to create various graphs via Microsoft Excel or any other statistical software. The software will log temperature every x amount of time which can be set from a second up to a day.

EasyDriver Stepper Motor Driver
The EasyDriver is a simple to use bipolar stepper motor driver that supports microstepping. It can be used to control 3-axis CNCs, robots, home appliances, etc. It's compatible with any source that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder 3/5V pads). Board is powered by 7V to 30V supply to power stepper motors with any voltage. It has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got a precision motor control. EasyDriver drives bipolar motors, and motors wired as bipolar. I.e. 4, 6, or 8 wire stepper motors.
This is the newest version of EasyDriver V4.4. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.
Note: Do not connect or disconnect a motor while the driver is energized. This may cause permanent damage to the A3967 IC.
Features
A3967 Precision Microstepping Driver
MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
Compatible with 4, 6, and 8 wire bipolar stepper motors such as popular NEMA 17
Adjustable current control from 150mA/phase to 750mA/phase
Compatible with Arduino GRBL G-code interpreter for driving 3-axis CNC machines
Breadboard compatible pins
Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds
