=Produce Overview=

The Serial Port module is specifically designed for Banana Pi. The module use Maxim MAX232 chip and DB9 port. So the user don’t need to connect Dupont Line and that avoid wrong wiring. User can use this module to debug Banana Pi easily.

==Produce Features==

1. Maxim MAX232 on chip
2. DB9 port

==Port==

*1. Banana Pi connection port
*2. DB9 port

==Product Parameters==

*1. Working voltage: 5V
*2. Two Drivers and Two Receivers
*3. Operates Up To 120 kbit/s
*4. Low Supply Current . . . 8 mA Typical

==Typical Application==
*1. Interface Translation
*2. Multidrop RS-232 Networks
*3. Low-Power Modems

==Product Specification==

=How to use =

Just insert the module to Banana Pi, like the below picture:

More information

The MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available.

These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5µW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.

==How to use module on BPI-M3==

![](uart.jpg)

![](uart 1.jpg)

*Video demo on youtube:https://www.youtube.com/watch?v=wh_PHCQOi_4

* Install the Minicom on BPI-M3

sudo apt-get install minicom

* Set the Minicom on BPI-M3

sudo minicom -s

A- Serial Device : /dev/ttyS2

E - Bps/Par/Bits : 115200 8N1

F - Hardware Flow Control : No

![](uart 2.jpg)

![](uart 3.jpg)

* Run the Minicom, then wait for the PC end to input text

sudo minicom

* Install the Minicom on your PC

sudo apt-get install minicom

* Set the Minicom on your PC

sudo minicom -s

Serial Device : /dev/ttyUSB0

Bps/Par/Bits : 115200 8N1

Hardware Flow Control : No

![](uart 4.jpg)

* Input the text," Hello BPI-M3 ", after finishing the setting.

sudo minicom

* Check if there's the text showing on the terminal window on BPI-M3

![](uart 5.jpg)

==Test bench==

*1. Connect the module to the Banana Pi
*2. Open the corresponding port through Putty
*3. Power up the Banana Pi, if the terminal print the boot information the module is OK!
