The Arduino MKR WiFi 1010 is the easiest point of entry to basic IoT and pico-network application design. Whether you are looking at building a sensor network connected to your office or home router, or if you want to create a BLE device sending data to a cellphone, the MKR WiFi 1010 is your one-stop-solution for many of the basic IoT application scenarios.
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.
