Description Arduino MKR WiFi 1010

The MKR WIFI 1010 is a significant improvement over the MKR 1000 WIFI.
It is equipped with an ESP32 module made by U-BLOX.
This board aims to accelerate and simplify prototyping of WiFi-based IoT applications thanks to the flexibility of the ESP32 module and its low power consumption.
The MKR WIFI 1010 also has a WiFi and Bluetooth module based on ESP32.
The board consists of three main blocks:

• SAMD21 Cortex-M0+ 32bit Low Power ARM MCU;
• U-BLOX NINA-W10 Series Low Power 2.4GHz IEEE® 802.11 b/g/n Wi-Fi; and
• ECC508 Crypto Authentication. ( data sheet )

The MKR WIFI 1010 features 32-bit computing power, the usual rich set of I/O interfaces and low-power Wi-Fi with a crypto chip for secure communication with SHA-256 encryption.
Plus, it provides easy-to-use 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 to the board (5V).
It has a Li-Po charging circuit that allows the Arduino MKR WIFI 1010 to run on battery power or an external 5 volt source, charging the Li-Po battery while running on external power. Switching from one source to the other is automatic.

Warning: Unlike most Arduino boards, the MKR WIFI 1010 runs on 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 may damage the board.
Although output to digital 5V devices is possible, bidirectional communication with 5V devices must be properly relocated.
