2. Soldering the headers

3. Plugging the board in

Once you have soldered the headers your 
board is ready to be placed into the desired 
mikroBUS

 socket. Make sure to align the cut in 

the lower-right part of the board with the 

markings on the silkscreen 

at the mikroBUS

 socket. 

If all the pins are aligned 

correctly, push the board all 

the way into the socket.

Turn the board upward again. Make sure 
to align the headers so that they are 
perpendicular to the board, then solder the 
pins carefully.

Turn the board upside down so that 
the bottom side is facing you upwards. 
Place shorter pins of the header into the 
appropriate soldering pads.

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.

4. Essential features

Bidirectional isolators based on 

TI’s Capacitive 

Isolation technology have many advantages 

over opto-couplers (performance, size, power 
consumption etc.). When used together with 
isolated power supplies, they block high volt-
ages, isolate grounds, and prevent interference 
from from noise currents. Since ISO1540 pro-
vides two isolated 

bidirectional channels for 

clock and data lines

, it’s suitable for use in ap-

plications that have multiple masters.

. On the board, the Texas

C pins, one on the 

mikroBUS

 connector 

(SDA, SCL), the other on the upper edge of 
the board (

). ISO1540 uses a 

silicon dioxide barrier that separates the 
logic input and output buffers. The board can 
use either 3.3V or 5V power supplies.
