Genuino 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
(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 th /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. 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 Genuino 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 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.
