4-20mA T Click is an add-on board in mikroBUS form factor. It's a compact and easy solution for adding an industry standard 4-to-20mA current loop communication protocol to your design. It features the ADuM1411 quad-chanel digital isolator, MCP4921 12-bit DAC as well as the XTR116 4-20mA current loop transmitter. The board communicates with the microcontroller via three SPI lines (SDI, SCK and CS). The board can be used with either a 3.3V or 5V power supply. An LED indicates the presence of power supply to the board.
