    My AHRC friends are saying the SATA pins on the chip on this board are not connected to anything and this was probably done to reduce board layers/size/cost. Oh well. Maybe next version? Would be great for video and other things that need storage volume and speed.

    R-pi people are big on using a powered USB hub. That isn’t an issue with pcDuino?

    I see SATA on the schematic. Is it pinned out? Can I connect a hard drive to it? Can I boot from that drive? This would be huge.

    I do get dropped bits now and then. Is that the issue with the old ones? Can I get a discount on a new set? :P

    Can you read signal strength with this? If so I would like to try using a pair to get a bearing on the transmitter.

    Can you read the signal strength out of these so you could use them to get a bearing on the transmitter?

    Doesn’t the Vin pin on the Arduino want 7.5V - 11V? Wouldn’t it be best if the booster was 9V instead of 5V? I have run into problems with using 5V on the Vin pin (look in the forums - powering your Arduino with 5V is a common beginner mistake). Much more stable if you use 7.5V or more. Seems it is designed for use with a 9V battery. Then you would use the 5V out on the Arduino to power your sensors and such. I could be wrong but this has been my experience.

    According to the datasheet you can’t set the I2C address:

    “The VCNL4000 has a fix slave address for the host programming and accessing selection. The predefined 7 bit I2C bus address is set to 0010 011 = 13h.”

    This means there is no way to have more then one on your I2C bus, correct? You might want to post that in the “Features” section before someone orders a bunch of them to create a sensor array. Would be nice if the board had a I2C to analog out so you could have more then one. Also, people will be lucky to get much more then 10 cm range.

    It rated for 3V not 3.3V, they should make that a bit more prominent I think. Easy mistake to make.

    Using it for I2C

    I connected mine the same way this page shows: example

    But I still get random crashes. I am using it with the MD25 motor controller and the 9dof sensor stick (SEN-10183). Seems like the Arduino shouldn’t be crashing even if there is junk on the I2C line. It should reject it or give bad data, not crash. I have 1k ohm pull ups on both sides of the converter. Any advice would be appreciated, thanks.

No public wish lists :(
