Fishino 32

Fishino 32 has 512 kB of ROM, 128 kB RAM, clocked at 120 MHz, native USB interface (is that Host Device), integrated RTC, support for microSD memory cards, WiFi module, stereo audio codec, battery power (plug and / or via the USB connector, 3-volt up to about 20 volts), automatic charging a LiPo battery (if any external power supply).
Ability to shutdown software all the card, leaving only fueled the standby processor; ability to wake from standby through an external pin or by RTC fixed times; Arduino UNO standard format; internal operating at 3.3 volts; DIGITAL pin 5V-tolerant, so there is no danger of burning the card shield to 5 volts.
