7 8 Mega Decade Programmable Adjustable SMD Resistor Slide Sensor Board E161

7/8 Decade:
This is "resistance substitution box" good low-cost alternative solution, can flexible and quick setting resistance range. For educational experiments, electronic engineering design or test trimming are excellent applications.
 
Ranges:
7 Decade: 1R to 9999999R
8 Decade: 1R to 9999999R or 0.1 to 9.9999999MR (0-10MS).
 
Resistance Tolerance: ±1%
Rated Power: 1/2 watt.
Design based on "resistors series" theorem. 1/2-watt tolerance +/-1% SMD resistors. High quality FR4 glass fiber PCB. With spare parts 7/8 pieces jumper caps Programmable Resistance. Max. Working Voltage: 200V.
 
Mega Sensor Shield v1 v2:
The board use of Immersion Gold PCB processing technology, the motherboard will not only all the digital and analog interfaces servo extended line order form out, but also ad hoc Bluetooth module communication interface, SD card module communication interface, APC220 radio frequency module communication interface, and RB URF v1 .1 ultrasonic sensor interface, independent of a more extended use convenient. For  beginners, not for the cumbersome and complex circuit connection and a headache, and this sensor expansion board truly simplify the circuit can easily be used to connect the sensor, a sensor requires only a general 3P sensor wire (regardless of digital cable and analog cable), complete the circuit connection, the preparation of the corresponding program to the  MEGA Arduin controller reads the sensor data, or receive wireless module return data, after arithmetic processing, and ultimately easy to complete your own interactive work.
