  • From the documentation, it appears that I can't connect this board's vin pin to a 3.7V lithium battery. The vin pin requires at least 4.2 V or the board will not run. Also, I also can't connect this board's 3v3 pin to the battery because that is too much voltage and it will damage the board. My conclusion is that it is not a straight forward way to power this board with a 3.7 V lithium battery. Is this correct? Dave

  • Can I buy straight break away headers so I can connect this to a custom board? The pitch appears to be about 1.058 mm which I can't find anywhere. Or in other words, anything that will help me connect this to a board.

  • Any response to this question?

  • Is there a way through S/W to pull up ain0 or do I need to use the 3.3v output with an external resistor? If you can do it in S/W, can you provide C++ code that allows me to configure the board to enable a pull up resistor on ain0. I use ubilinux with mraa. Thanks!

  • If you can provide a C++ sniplet that allows me to configure to enable a pull up resistor for ain2 and ain3, that would be great. I use ubilinux with mraa (the code i use is posted below in a comment about 5 months ago).

    Thanks!

  • So happy to see this tutorial - should help a lot of people. I notice that it has a couple of broken links: "Download zip file of the repository" and the repository itself. Thanks for the tutorial!

  • I have a question: I have a battery block. Does the battery block power this block so I don't have to be tethered?

  • As it turn out, the problem of implementing a simple bend sensor appears more difficult with this block. I need a pull up resistor and I don't have a 3.3v source with any of the blocks that I have. So it appears that, to use this block, I need to buy another block with a 3.3v source and build a custom block with the pull up logic. So I need: 1) this block 2) another block with 3.3v source 3) build a custom block with pull up resistors to use a simple bend sensor. There has to be a better way to build a wearable device. This board needs to be implemented so users can place resistors for their pull up sensors for all analog imputs. If no resistor is used, the line isn't pulled up. There are so many sensors out their that need pulling up. I'm obviously frustrated.

  • OK, I figured out the problem. I can't simply connect the to bend sensor leads to this board. I need to add my own pull-up resistors (should have known). Dave

No public wish lists :(
