– Arduino Nano 33 IoT – small, secure, and Internet-connected. (Pre-order here with headers or here without headers) – Arduino Nano 33 BLE – small, low-power, and Bluetooth-connected.

Despite the differences in size and microcontroller, the Arduino Nano and Micro share some similar pinout configurations. They both have two GND pins, two reset pins, one AREF pin, and three power ...

The Arduino Nano is powered by an Atmel ATmega328. It's an 8-bit AVR microcontroller that operates at a clock speed of 16 MHz and comes with 2 KB SRAM, 1 KB EEPROM, and 32 KB flash memory.

Finally, the Nano 33 BLE Sense is available for $29.50 and comes with a range of extra sensors to support wearable device and gesture-based projects. Otherwise it has the same basic tech specs as ...
