1. Introduction

Once you have soldered the headers your 
board is ready to be placed into 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 of the pins are 

aligned correctly, push the board all 

the way into the socket.

4. Essential features

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 
bottom side is facing you upwards. Place 
shorter parts of the header pins in both 
soldering pad locations.

USB UART Click

 with it’s 

FT232RL

 

IC 

gives additional serial UART communication 
via USB cable.

 

The 

FT232RL 

contains 

integrated 1024 bit EEPROM, 128 bytes 

long receive buffer, 256 bytes long transmit 
buffer, configurable CBUS I/0 pins and entire 

USB protocol handled on the chip. The board 
contains RX and TX LED diodes that indicate 
the transmit and receive data via USB.

USB UART Click

 is an accessory board in 

mikroBUS

 form factor. It’s a compact 

and easy solution for adding serial UART 
communication via USB cable. It features 

FT232RL

 USB-to-UART interface module 

as well as USB MINI B connector. USB UART 
Click

 communicates with target board via 

UART interface. The board is designed to 

use 3.3V or 5V I/O level.

 

It has a LED diode 

(GREEN) that indicates the presence of 
power supply.
