Hi,

Currently with me I have an Arduino Uno, Xbee WiFi Shield, and RN171xv WiFi Module. For my project I need to use more i/o ports and I don't want to use other boards to increase ports. What I want is i/o expansion shield and I have found one (The Picture). My concern is how can I assemble the expansion shield together with my RN171xv WiFi Module on my Uno? Please advice me on this matter. If you have any better i/o expansion shield rather than what I found, please inform me.

Thanks! :D

Cheers!!

Does this give you more inputs or outputs?  From the looks of it, it looks like a shield that just brings all of the existing pins up in a different format (three pins for data/ground/power, xbee, etc.).

Hi,

Can you suggest me which i/o expansion is the best for arduino uno and it also can be assemble with xbee wifi shield + RN171xv wifi module?

Thanks mate! :D

Maybe something like: https://www.adafruit.com/products/593

Hi,

I actually need a complete i/o expansion shield that is in the market. This is the one I found: http://www.robotshop.com/pwm-expander-shield-arduino-3.html.

There are many of them that I can buy, but the real concern to me is I want to connect a WiFi module on my arduino uno and also the i/o expansion port. Is there any suggestion that you can provide me?

Thanks mate! :)

Note that the description of that shield only mentions output. Nothing there about input.

How about this, currently on kickstarter (short URL http://kck.st/164ObLg) It uses only the I2C port on the Arduino, so all the other pins are free and you can change the I2C address if that clashes with something else. As supplied, you get 58 extra pins which can be individually set to either input or output. It uses a FPGA, so if you wish, you can reprogram it to include other functions.
