[Brian Dorey] just released a board that allows for 8 analog inputs on the Raspberry Pi with a 16-bit resolution that is much higher than any Arduino-based build.

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...

Software-configurable systems enable industrial OEMs to deliver unprecedented flexibility to the factory floor, while simplifying product complexity. By introducing the Arduino OPTA platform for rapid ...

Assume that you need to log some of your readings from the input pins of your Arduino Uno (or MEGA, etc.) dev board which needs to work standalone. The proper way is to store the log in an SD card ...
