It has almost similar specifications as the Nano's microcontroller, which features 16 MHz clock speed, 32 KB flash memory, and 1 KB EEPROM. However, it comes with a slightly larger SRAM of 2.5 KB.

At the heart of the Nano 33 BLE Rev2 is the nRF52840 microcontroller, which comes with 1MB of CPU Flash Memory. The board runs on the Arm Mbed OS, an open-source operating system that works ...

Wi-Fi and Bluetooth Connectivity: Equipped with the ESP32-S3 microcontroller—a fan favorite in the IoT community—this board is fully Arduino-ready and supports wireless and Bluetooth connectivity.

Powered by the ESP32-S3 (Ublox NORA-W106-10B) microcontroller, the Nano ESP32 packs serious performance into the Nano form factor, featuring: 8 MB internal PSRAM / 16 MB external flash memory ...

The cheapest and simplest of the new lineup is the Nano Every, which costs $9.90 and is based on the ATMega4809 microcontroller. It runs at 20 Mhz and comes with 48KB of Flash and 6KB of RAM.

The Nano, just as its name suggests, is the smaller board between the two, and interestingly, also the tiniest ever produced by Arduino. It comes in a light seven-gram weight, with dimensions of ...
