Arduino Releases Nano ESP32

So far we used to use Espressif’s ESP32 microcontroller as a generic DOIT ESP32 DEVKIT or LOLIN D32 Pro or HUZZAH32 or similar board with Arduino IDE (to use Arduino compatible sketches). Now, Arduino has officially released a version of Arduino Nano which uses Espressif’s ESP32 microcontroller. This is powered by the ESP32-S3 (as Ublox NORA-W106-10B), the Nano ESP32 featuring:

• 8 MB internal PSRAM/16 MB external flash memory
• 512KB SRAM and 16KB of RTC SRAM
• Dual-core CPU at 240 MHz clock speed
• USB-C programming port

What This Means to the Generic Nano ESP32 World?

It means another ESP32 board in the family. By using Espressif’s ESP32, probably we will have more organized libraries which are compatible with Arduino IDE out of the box. The Arduino IDE 2 already offers plug-and-play support and also debugging. The board is compatible with the Arduino IoT Cloud. Nano ESP32 supports micropython and all the things which the ESP32 microcontroller supports.

But, Is Not It Late For ESP32 on Arduino Board?

Yes. It is late and also a costlier option to get an ESP32. But it is a fact that the Arduino project needs monetary support and to make the ESP32 microcontroller official, we required a board from Arduino as a brand. We used the generic ESP32 board with typical “Chinglish” documentation. Now we have a high-quality official board with the support of official IDE and libraries. The good documentation and easy support of IDE will make ESP32 more popular.

The Nano ESP32 is far more sophisticated than the generic version. It is good for children. The generic version is good for real deployment as a DIY project.

There are minor differences with the generic ESP32 board. For example, the built-in LED Pinon Nano ESP32 is at number 13 (it is number 2 in generic). There is already some documentation to get started:
