SD Card support

Are there any plans to add SD Card support for ESP32 MicroPython?
It is available in Pycom's Micropython version, but for some reason I prefer to use the MicroPython build.

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

Let me know if anyone finds a real tiny board using STM32F4 in QFN48 package. I can't seem to find one (an the one I designed myself went up in smoke :D ). Not in QFN48, but quite small, only with limited pins exposed http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&LH_BIN=1&_nkw=F4+STM32F405+Flig...

Re: EMW3165

You can easily connect EMW3165 to Diiscovery ST-LINK SWD port. Remove CH3 jumpers and connect SWCLK, GND, SWDIO, NRST from CN2 to EMW3165. No need to connect VDD. Update st-link firmware first, than you can read the content of the flash and save it as backup. I've tested it with WiFiMCU board. http:...
