HVADC Pi HAT - Ideal for Battery Measurement and EV applications using Raspberry Pi

**-

High Voltage Analog Digital Conversion ADC Raspberry Pi Hat

Problem Statement-

1. Raspberry Pi Zero, 2,3, 3B, 4B modules do not provide ADC ports however Analog measurement is very important and could not be bypassed.
2. Further Raspberry Pi pins are 3.3V tolerant thus the available Raspberry Pi Hat for ADC could only measure upto 3.3V DC Signals

Solution:

1. 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

2. 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.

Salient Features:

1. Unused Analog Inputs causes noise issues and hence could be Pull Up/down using easy to solder 1206 resistors
2. Each Channel is protected with overvoltage at Raspberry Pi side for safe and Reliable Operation
3. 8 Digital Inputs/Outputs are also given access of Raspberry Pi
4. I2C Interface is provided for connecting other I2C based sensors
5. UART Interface is also provided access of the Raspberry pi for Intercommunication between different Boards

Benefits:

1. 16 Channel Analog Inputs
2. 10 Bit and 12 Bit Resolution Variants Available
3. Reliable Measurement from 3.3VDC to 100 VDC on each channel
4. Overvoltage Protection on each Channel
5. Easy to solder Voltage- Divider 1206 Resistors
6. Easy to use Pull up/down 1206 resistors
7. Uses SPI Interface of Raspberry Pi
8. Access to I2C and UART Interface
9. Access to 8 Digital I/Os from Raspberry Pi
10. Compatible with Raspberry Pi Zero, 1,2,3 and 4 versions

This Hat is ideal for Professionals, Hobbyists, Students and Engineers working on Raspberry Pi where Analog signals need to be measured

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
