Aaron Weiss from SparkFun took part of the board design and walked me through the winding road of getting a product out the door. The development has been an ongoing process, with new features and bug fixes introduced on a regular basis. To make it super-loud-and-clear: Download the software package with libraries and examples from the website and you’re good to go. Ytai Ben-Tsvi July 9, at 6:

IOIO-OTG – V – development board for Android, OS X, Windows – Kamami

Unlike the DX version and other questionable clone, the Seeed boards are manufactured with the best standards and are individually testing. Views Read View source View history. Ofg are a professional review site that has advertisement and can receive compensation from the companies whose products we review.

It is indeed a good idea.

IOIO-OTG board review |

I’m so glad that there are people like you! I have connected my homemade power cable to it from 9V battery or V mains adapter. Found out that the output FET does not get right driving voltage level to turn on. I will check that out. Privacy policy About Geeetech Wiki Disclaimers.

IOIO-OTG – V2.2 – development board for Android, OS X, Windows

PIC wars among hobbyists, people tend to forget that what matters is the application and then making the best microcontroller choice accordingly.


If you still can’t find the examples you are looking for, simply browsing the web will result in a ton of information and examples that show you how to communicate with all of the great pieces of hardware within your Andriod device.

The project tree has many files. To figure out what the errors are, Eclipse has tab called ‘Problems’ that shows you what errors you are getting. The programming language used to write an Android app is Java.

My main goal in this project is to make it available and useful for as many people as possible. This can mean many things. Arduino is awesome for what it’s good at, which is IMHO for standalone operation.

We have a blog post that shows or has links to many well documented example projects, with source code. In the PC world it would provide an attractive competition as well to boards of similar capabilities, and once again, the savings on software development time are huge.

January 25, at In my tests the PWM outputs generated the PWM signal at Hz frequency which is suitable for example for LED dimming and should be suitable for hobby servo controlling at ms pulse lengths if you need to get different PWM frequency like commonly used 1 kHz as given by Arduino Firmata or used by some industrial PWM systems, you need to make your own program.


The Android device should show that USB debugging is connected in the notification bar, in addition, the Android should indicate it is charging. Marketing has traditionally been quite low on my priority list: The IOIO can be supplied by anywhere between 5VV and the input voltage is also exposed on the Vin pins on the board, as a convenient bypass for your circuit.

Innovative and really cost effective, too. If you continue to use this site we will assume that you are happy with it. Did the 9v battery work on the ioio board?

I’m currently considering my options for how to reduce the end-user price while leaving a little something for myself too. Notice that there is iioo small red x next to the project name. I did some hardware debugging. June 6, at 5: That is really generous to leave out your royalties, it shows true dedication to the project.

The easiest way to get the apk file on your device is to plug the device into your computer.
