The Arduino Nano uses a bootloader for handling programming the MCU, ... can’t be used as output), and has 2 more GPIO: pin 3 and 6 as D23 and D24 instead of another GND and VCC pins.

An Arduino Nano is the heart of the build, paired with a shield that lets it run a number of servo motors. The servos, one per key, are each assembled into a 3D-printed bracket with a cam-driven ...

While the pinout is very similar to the Arduino Nano’s, there are four (12-bit) analogue inputs rather than eight (10-bit). Some digital GPIO pins are numbered differently too.

The power of Espressif’s ESP32-S3 meets Arduino’s unmatched customer experience, documentation and community — all in the compact form factor of the Nano. Provides support for both ...

Nano 33 IoT: Equipped with Wi-Fi and Bluetooth connectivity and a six-axis inertial measurement unit (IMU) for motion tracking Arduino projects. MKR Zero: Different from the Arduino Zero.
