In summer 2023, Arduino launched the Nano ESP32. Based on the ESP32-S3 from Espressif, the new board features 2.4 GHz, 802.11 b/g/n Wi-Fi, and long-range Bluetooth 5 (LE) connectivity in a Nano form factor. The Nano ESP32 is not the first Arduino board sporting a processor from Espressif, but this time it’s the main act instead of just a wireless communication module supporting another MCU. Elektor interviewed Alessandro Ranellucci (Head, Arduino Makers Division) and Martino Facchin (Hardware & Firmware Manager, Arduino) about this collaboration between Espressif and Arduino.
