Description How To

The Redpark TTL Cable for iOS is the latest revision of the popular RedPark Serial Cable. The main difference between this and the original is that a RS-232 serial to TTL adapter is no longer required. This means you can connect it directly to an Arduino using only jumper wires. No soldering and no adapters required.

The RedPark cable is the first and only cable approved by Apple to allow hobbyists to connect their iOS devices to external microcontrollers and sensors! With this cable, you can open up your iPhone, iPad, or iPod touch and let your imagination run wild! Use external sensors in your iOS apps! Talk to an Arduino with your iPhone! The possibilities are unlimited!

Also, be sure to check out Alasidar Alan's book, iOS Sensor Apps with Arduino for ideas and instructions!
  • Does not require soldering
  • Enables development of iOS apps for private use in homes, schools and offices
  • Connects iOS devices to microcontrollers and sensors!
  • Designed for use with iPhone 4S, iPhone 4, iPhone 3GS, iPod touch (fourth generation), iPad 2 and iPad.
  • Used in conjunction with the Redpark Serial Cable SDK and sample code. Together these tools enable you to write iOS apps that communicate with serial devices.
  • Requires iOS 5.0.1 or later.

Could be better... November 17, 2012
Reviewer: Aaron Brooks from Saint Paul, MN United States  
Just wanted to second what the previous reviewer stated.  There seems to be a grounding issue in these cables.  I had hoped it was just true for the first cable that I picked up, but it seems to be a design flaw.  My work around for this has been somewhat different, however.  If the cable is unplugged on the 30-pin end, and the GND unplugged, the 30-pin plugged back in, and finally the ground plugged back in, the same effect is achieved.  

The SDK provided is decent, but it would be nice if RedPark were to put out a decent bit of documentation on it.

Here's to hoping a 9-pin cable will be better - and cheaper.

things you should know October 26, 2012
Reviewer: Paul Payne from Seattle, WA United States  
It works.

Things that aren't so great:
- If the app closes or your iOS device goes to sleep, you'll need to power your arduino off, unplug the cable, make sure your app is running and then plug them back in.
- You need to disconnect the cable from the arduino when programming the arduino. - To get the cable to connect again after programming, you need to follow this protocol: a) unplug cable from arduino and iOS device, b) reset arduino, c) plug in cable to arduino, d) plug in cable to iOS device. If you don't unplug from both ends, it won't work.
- You cannot power your iOS device from this cable. You may be able to use the dockStubz+ from CableJive to add power, depending on the iOS device.

I'd give less stars if I didn't know that these problems are mainly due to iOS being a closed hardware system. This cable is a great attempt at opening it up, but there are still issues related to the closed nature of the iOS hardware.
