High Voltage ADC Raspberry Pi HAT

High Voltage ADC Raspberry Pi HAT with Overvoltage Protection. You can measure any analog voltage level using appropriate resistors. Designed by PCB Must in India.

The HVADC Pi Hat developed provides 16 channels of ADC with 10/12 bit resolution over SPI interface with overvoltage protection and provision for connecting unused ADC pins to 3.3V or GND with the help of easy to solder 1206 SMD resistors.

Theoretically there is no upper limit on analog voltage for measurement in this board. Easy to use 1206 resistors in the voltage divider on each channel lets you measure up to 100V DC on each channel in a precise manner and could be used for measuring any DC Voltage with the help of resistors.

What Makes this Hat Unique?

Right Now there is no single board which allows all the things we allow. A normal person would need to use at least 2 different boards along with a breadboard at least to provide the same functions we are providing with a single HAT.

The HAT is optimum to use for Noisy and Industrial Applications as well as it contains certain noise protection, Overvoltage Protection and default settings could be changed for the analog inputs from Pull Up To Pull Down and could be left floating as well.

The main specialty of our board is anyone can use this board and no special soldering skills are required as this contains 1206 resistors which are very easy to solder respectively.
