mikroElektronika Bluetooth2 click User manual

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.
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.

0 100000 023372
Bluetooth2 Click™is an accessory board
in mikroBUS™form factor. It’s a compact
and easy solution for adding bluetooth
module to your design. It features
BLUEGIGA WT41 Bluetooth® 2.1 with EDR
module. Bluetooth2 Click™communicates
with the target board microcontroller via
mikroBUS™UART (Tx, Rx), SPI (MOSI,
MISO, SCK, CS), SDA, SCL, RST, AN, INT and
PWM lines. The board is designed to use
3.3V power supply only. LED diode (GREEN)
indicates the presence of power supply.
Bluetooth2 click
Bluetooth2 Click™ with it’s WT41 contains all
the necessary elements from Bluetooth®radio
to antenna and fully implemented protocol
stack. It is equipped with iWRAP rmware
which enables users to access Bluetooth®
functionality with simple ASCII commands
delivered to the module. It is ideal for
developers who want to integrate Bluetooth®
wireless protocol with limited knowledge of
Bluetooth®and RF technologies. The board is
optimized for long range applications.

6. SMD jumpers
The Bluetooth2 Click™ board
uses four UART interface
lines. Two of them are for data
transfer between WT41 module and main
board microcontroller (Tx and Rx) and other
two are for hardware ow control (CTS and
RTS). If you want to use CTS and RTS lines,
solder two zero-ohm SMD jumpers J1 and J2.
They are not soldered by default.
