2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 4-20mA T click 2 3 1. Introduction 4. Essential features 4-20mA T Click with its ADuM1411, MCP4921 and XTR116 ICs is ideal for using in field of industrial process control and test systems. It serves as interface between sensors or instruments (connected Turn the board upside down so that Turn the board upward again. Make sure to microcontroller) and controlled peripherals bottom side is facing you upwards. Place to align the headers so that they are in industrial standard current loop. The shorter parts of the header pins in both perpendicular to the board, then solder the board receives the input digital signal from soldering pad locations. pins carefully. the microcontroller and sets the output loop current (4-20mA). 4-20mA T Click is an accessory board in mikroBUS form factor. Its a compact and 3. Plugging the board in easy solution for adding 4-to-20mA industry click standard communication protocol to your Once you have soldered the headers your design.
