You may be interested in a project published to the Hackster.io website earlier this year providing instructions on how to create a simple wearable heart rate monitor using an Arduino Nano R3.

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

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 ...

The Nano is a nice and modest update to the older Arduino Micro/Nano boards. The Arduino Nano 33 IOT has an ESP32 onboard (WiFi + Bluetooth) and crypto onboard with the uBlox NINA-W10.
