The board have micro-SD card, USB host, USB-OTG, all ports break out on connectors and ARDUINO platform connectors.
MAPLE support for F4 is on the way, so this board will be one powerful Arduino alternative.

Nice; I`d like to have a similar very low cost board with NXP LPC3130 or 3131 which has small onboard memory but has usb 2.0 hi speed otg and two I2S-bus interfaces, two master/slave I2C-bus interfaces, etc. It can not run linux w/o external ram, but can be used to develop a bare metal code for hi speed multichannel data acquisition.
