I have a USBDroid I am going to connect up soon as an alternative to try. I
suspect that the Arduino will be slightly higher power and slightly higher
price - but not much. On the other hand, the hardware inputs on the usbdroid
could more flexible, including an SD card built in. It could be useful as stand
alone mode, like logging NMEA.
USB Droid AUS$69.95 (compared with IOIO AUS$55)
- ATMega8u2 (mainly used for USB comms, but can be reprogrammed)
- ATmega328 (main cpu - 32K flash, 2KRam, 1K EEPROM)
- 14 GPIO (6 PWM)
- 8 Analogue inputs
- 3.3 or 5V internal, but 12 volt input accepted
- 2 hardware UART (I have added lots of other software, more limited
speeds though)
- I2C, SPI
- SD Card integrated
- USB Client (programming, debugging etc)
- USB Host (connect to Android)
Other advantages of IOIO - more IO Pins, extra UART, integrated charging. And
now that it supports ADK it really is more flexible.
My interest in the Arduino (AVR) side is more for stand alone equipment (my
projects are commercial, nothing to do with gliding), where an android phone /
tablet is plugged in like a terminal - ie. To download logs, update software,
configure etc.
