  • Can I use this with LiPo batteries?

  • I can confirm this. I use this display and it’s big brother. Both allow you to update one line, a series of lines or the entire screen in a single SPI command. It’s trivial really.

  • STM32F4 needed the resistors, but it works great! I’m driving it with a Cerb40 II board from GHI.

  • One of the other micro motors you sell has a ratio of 298:1. Is this more precise or is that just the product name?

  • I’ll try it and report back. That link seemed to say they needed the resistors because their IO logic pins were ~4v. Stm32 is 3.3v :)

  • Does it make a difference if I’m using an STM32F4 to drive it? I won’t bit bang, I’ll be using the SDIO hardware feature of the chip? I have internal resistors, they’re not strong enough?

    I’ve been working with SD cards for a long time now using this chip. But they’ve always been on the same board.

  • Do I need to add anything to this or can I wire it directly to my microprocessor board? I know normally there are some pull up/down resistors.

  • lol, according to your link the 13MP Galaxy S4 is better than a Cannon 5D Mark II 21MP DSLR. …I’m guessing the person in charge of uploading those pics owns the Galaxy.

  • …Yes and yes, using the serial interface. Check the video on this page at 6:05. The interface is simple.

  • lol, their video didn’t render in IE10 (with or without compatibility view). Thanks. …Seriously though, embedded YouTube videos work on every other site. I think SparkFun should checkout their markup.

No public wish lists :(
