MKR1000 Arduino WiFi Board Module
MKR1000 overview
Arduino WiFi Board MKR1000 is a powerful board that combines the functionality of the Zero and the Wi-Fi Shield. It is the ideal solution for makers wanting to design IoT projects with minimal previous experience in networking.
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. This WiFi board is based on the Atmel ATSAMW25 SoC (System on Chip), which is part of the SmartConnect family of Atmel Wireless devices, specifically designed for IoT projects and devices
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 emerging IoT battery-powered projects in a compact form factor. The USB port can be used to supply power (5V) to the board. This Arduino board is able to run with or without the Li-Po battery connected and has limited power consumption.
