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 R click 2 3 1. Introduction 4. Essential features 4-20mA R Click board is ideal for using in field of industrial process control and test systems. The board serves as receiver in 4-20mA current loop standard. It receives output current (4-20mA) from transmitter Turn the board upside down so that Turn the board upward again. Make sure and convert into a voltage (0.4-2V). Then bottom side is facing you upwards. Place to align the headers so that they are through the AD converter sends signal to shorter parts of the header pins in both perpendicular to the board, then solder the main board microcontroller. This board and soldering pad locations. pins carefully. the 4-20mA T Click board together form a complete 4-to-20mA current loop standard. 4-20mA R 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. It features INA196 current shunt board is ready to be placed into desired BOARD monitor, MCP3201 12-bit ADC as well as mikroBUS socket. Make sure to align the www.mikroe.com TPS61041 DC/DC boost converter. 4-20mA cut in the lower-right part of the board R Click communicates with target board with the markings on the silkscreen at the 4-20mA R click Manual microcontroller via mikroBUS SPI (SDO, mikroBUS socket. If all of the pins are ver. 1.01 SCK, CS) and EN lines. The board is designed aligned correctly, push the board all to use 3.3V and 5V power supply.
