# Octopus Analog Voltage Divider Brick OBVoltage(EF04039) 

## Introduction

The Voltage Divider can detect the supply voltage upto 50V and  is based on resistor(1K and 15K Precision resistors).

## Characteristics

 The voltage detection module allows the input voltage to reduce 16 times. As the micro:bit analog input voltage is 3.3V, so voltage detection module's input voltage can not be greater than the 3.3Vx16 = 52.8V. Because of the micro:bit's 10 bit ADC, that means sampling resolution are 0.003225V（3.3V / 1023）.So the module's minimum input voltage is 0.00489Vx3.3=0.01064V.   
 Tips: All of Octopus bricks have supported Scratch programming.
