The Arduino MKR WIFI 1010 includes 32-bit computational power, the usual rich set of I/O interfaces, and low power Wi-Fi with a Cryptochip for secure communication using SHA-256 encryption. Plus, it offers ease of use Arduino Soware (IDE) for code development and programming. All of these features make this board the preferred choice for the emerging IoT baery-powered projects in a compact form. Its USB port can be used to supply power (5V) to the board. It has a Li-Po charging circuit that allows the Arduino MKR WIFI 1010 to run on baery power or an external 5 volt source, charging the Li-Po baery while running on external power.
