Arduino MKR1000 has been designed to offer a practical and cost
effective solution for makers seeking to add Wi-Fi connectivity to their
projects with minimal previous experience in networking.It is based on
the Atmel ATSAMW25 SoC (System on Chip), that is part of the
SmartConnect family of Atmel Wireless devices, specifically designed for
IoT projects and devices.
The ATSAMW25 is composed of three main blocks:
SAMD21 Cortex-M0+ 32bit low power ARM MCU
WINC1500 low power 2.4GHz IEEE® 802.11 b/g/n Wi-Fi
ECC508 CryptoAuthentication
The ATSAMW25 includes also a single 1x1 stream PCB Antenna.
The
design includes a Li-Po charging circuit that allows the
Arduino/Genuino MKR1000 to run on battery power or external 5V, charging
the Li-Po battery while running on external power. Switching from one
source to the other is done automatically.A good 32 bit computational
power similar to the Zero board, the usual rich set of I/O interfaces,
low power Wi-Fi with a Cryptochip for secure communication, and the ease
of use of the Arduino Software (IDE) for code development and
programming. All these features make this board the preferred choice for
the emerging IoT battery-powered projects in a compact form factor.The
USB port can be used to supply power (5V) to the board.The Arduino
MKR1000 is able to run with or without the Li-Po battery connected and
has limited power consumption.
The MKR1000 Wifi module supports certificate SHA-256.
Warning:
Unlike most Arduino & 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.
