Good Morning. What is the most affordable board that supports both WiFi and Bluetooth connectivity, while also featuring an ATmega328 chip?

Because only the ATmega328 chips will support the Adafruit Wave Shield that I'm using for my project.

use an Arduino Mega using hardware serial ports to communicate with an ESP32 note that the Mega uses 5V logic the ESP32 3.3V therefore you require a potential divider on the Mega Tx to ESP32 Rx line note that you cannot use WiFi and Bluetooth at the same time on the ESP32 - would this be a problem…

It wouldn't be. Thank you for the help!

Why are you restricting the choice to ATmega328 chips ?
