Genuino MKR1000 is powered by Atmel SAMD21 Cortex-M0+ SoC and built-in WINC1500 Wifi chip. It comes is a smaller form factor and also as an on-board LiPo battery charging circuitry.
There's also the usual set of I/O interaces from the Arduino team, including low power Wi-Fi with soft AP SSL support with an ATMEL cryptochip for securing communication and the ease of use of the Arduino IDE so you can develop code and program your board. This is a great choice for IoT battery-powered projects.Unlike most Genuino boards, the MKR1000 runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board. While output to 5V digital devices is possible, bidirectional communication with 5V devices needs proper level shifting.
