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.
How fast does this operate? My problem with fingerprint scanners (I use them on a daily basis) is speed. The ones I use have to be swiped, which doesn’t always work, and then there’s a lag (probably due to windows). …Before I buy one of these I want to make sure it’ll be nearly instantaneous.
No public wish lists :(
