I made a simple labeled wiring diagram for them, and for you here are the simple costs:

• ATOM Echo Smart Speaker Dev Kit — $13.50
• Push Buttons — $0.28
• Slide Switches — $0.70
• Li-Ion Battery — $7.95
• M/M Jumper Wires — $1.95
• Adafruit Mono Audio Amplifier — $3.95

Which is a total of $28.33. And to clear things up even more, the smart speaker has a built-in mic and speaker and that's basically it. The handheld only had to have button to stream your voice to the 01 Server running on the cloud or your pc.
