Low power Stackable Bluetooth Shield V2.1
This Bluetooth shield is a serial port Bluetooth module (Slave)
breakout board, and it compatible with Arduino, you can
directly plug in with Arduino and use the UART port for Bluetooth
communication.
Specifications :
Microprocessor:CSR BC417
PCB size:53.3mm X 47mm X 1.6mm
Indicators:PWR ,State
Power supply:5V DC
IO:3
Communication Protocol:UART/Bluetooth 2.0
RoSH:Yes
1,Now the new shield is full Arduino footprint , and add the
stackable socket for connecting with other Arduino shield like
Ethernet shield , SD card shield.
2,Add a power switch for the shield, now you not just use it with
some 5V interface board like Arduino, but also now can compatible
with many other 3v3 boards like IFAT-32, Leaf Maple, and so on.
3,The BT shield v1.1 just can communicate with Arduino board, and
it’s inconvenient to change its setting by AT command through USB.
Now the new board has a switcher, you can change the module
connection, so when you put the switcher to the “To Board” side, it
can control by Arduino or IFLAT32, but to “To FT232” side, it
connect to the FT232D IC, you can use the Arduino IDE or other
serial monitor software to send it the AT command.About the AT
command , you can find more detailed information
here.
4,In the free area, we provide you a prototype area, and you can
build a small circuit there for your Bluetooth
