  • 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 :(
