Attention:

Due to technical requirements components, please do not hand directly connected

Touch. Core board and development system contains static-sensitive devices. Quiet Electrical charge easily accumulate in the human body and the device can not detect possible Damage to equipment, it is recommended to take anti-static measures, it is recommended not to hand. Touch, stored in anti-static effect devices.


Raspberry Pi Expand Module Serial
Infinity cascade IO expand module

This module is designed specifically for the Raspberry Pi IO expansion modules. The module expand 32 IO, Multiple modules can cascade, infinity cascade,infinity GPIO.


I2C GPIO expand module

This module is designed specifically for the Raspberry Pi IO expansion modules. The Module use I2C bus to connect to Raspberry Pi. The module expand 8 Bidirectional GPIO and wit isolation protection function which can effectively excessive external voltage. There are 8 I2C address, you can choose one of them through setup the jumper. Multiple modules can cascade and maximum cascade 8 modules!



Prototype development module

The Prototype development module is designed specifically for the Raspberry Pi. The module suitable enthusiasts and user can weld peripheral to the module;The module expand some amphenol connector and some SMT, so the user can finish prototype test easily.


Berryclip expand module

The BerryClip module is designed specifically for learning how to use the GPIO of Raspberry Pi. There are 6 multiple color LED, 1 button and 1 Buzzer on the module.


Berryclip(DIY) expand module

The module is not the end product, you need weld them by yourself. The function of the module is the same as BerryClip module.


UNO compatibility module

The module makes Raspberry Pi compatible with Arduino Uno and many Arduino Shields. The module’s GPIO is the same as Arduino Uno and you can choose the voltage of GPIO between 5V or 3V through setup jumper.


T Electric level convert module

The module expand the GPIO of Raspberry Pi to breadboard. It convert 3.3V electric to 5V electric level, then the Raspberry Pi can connect many 5V electric level peripheral.


IO extraction module

The module expand all of GPIO of Raspberry Pi to breadboard.




RTC expand module

The RTC module is specifically designed for Raspberry Pi. There is a 0.2uF SuperCapacitor on the board to keep the real time for a long time after the Raspberry Pi has power off.


AD/DA expand module

The AD/DA module is specifically designed for Raspberry Pi. There is 8bit high resolution DAC and ADC on one chip.


I2C electric level conversion expand module

The I2C electric level conversion module is specifically designed for Raspberry Pi. The module convert the 3.3V of I2C electric level to 5V level or convert 5V to 3.3V.


I2C electric level conversion expand module

The Serial Por module is specifically designed for Raspberry 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 Raspberry Pi easily.



1:Product Specification:



2:Produce Overview:


The Serial Por module is specifically designed for Raspberry 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 Raspberry Pi easily.

3:Produce Features:


  • Maxim MAX232 on chip

  • DB9 port



4:Port:




5:Product Parameters:


  • Working voltage: 5V

  • Two Drivers and Two Receivers

  • Operates Up To 120 kbit/s

  • Low Supply Current . . . 8 mA Typical



6:Typical Application:


  • Interface Translation

  • Multidrop RS-232 Networks

  • Low-Power Modems



7:How to use:


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



8: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.

8.2:Testbench

  • Connect the module to the Raspberry Pi

  • Open the corresponding port through Putty

  • Power up the Raspberry Pi, if the terminal print the boot information the module is OK!
