STD Raspberry PI
Mode:
This project is basically a shield for the Raspberry PI and adds following features:
* Buffer for IOs: it utilizes the SN74HC244NSR (which is a Octal Buffers and Line Drivers With 3-State Outputs chip)
* MCP3008T-ISL: 2.7V (4-Channel/) 8-Channel 10-Bit A/D Converters with SPI Serial Interface
The Buffer for IOs is used due to the fact, that the inputs on the Raspberry PI are sensitive and are not protected. So the SN74HC244 is doing the job here.
The ADC IC MCP3008T-ISL is an 8-Channel 10-Bit ADC which adds an ADC functionality to the Raspberry PI.
