Today's SD cards have 4 data pins: DAT0-3.Awesome, thank you! Yep, 1/8 in my case too. Seems everyone uses a little bit different description.
And moreover, flexibility in jumpers to choose chip selects.This would work great with the prop board on the bottom side, assuming they would play nice together sharing the miso/mosi/sck. Would make everything nice and compact. Great job.
Thanks! Yep, I hope to have them up on Tindie in a couple days when the low profile headers come in.
The male header pictured on the side shot is missing its isolation, but the included headers will of course have the isolation.
Looks like onehorse has some competition for his appallingly teensy peripheral series...
Nice layout, did it take many goes for the PCB fab to get all the milling right without things flying apart during machining?

unfortunately, the use in pin13 for spi-clk inhibits is use together with i2s, where pin13 is the only i2s0.rxdx0 possibility.
Thanks! It won't work under the Teensy due to the 3V/GND headers blocking card removal/insertion, but I may make an upside down version in the future.
