Arduino MKR WiFi 1010 Arduino

DESCRIPTION

The MKR WIFI 1010 is a significant improvement on the MKR 1000 WIFI. It’s equipped with an ESP32 module made by U-BLOX. This board aims to speed up and simplify the prototyping of WiFi-based IoT applications thanks to the flexibility of the ESP32 module and its low power consumption.

The board is composed 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.

The 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 Software (IDE) for code development and programming. All of these features make this board the preferred choice for emerging IoT battery-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 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 done automatically.

Please Note:

• Warning: Unlike most Arduino boards, the MKR WIFI 1010 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.
