Hi Bruce,
Nice job, I have done the opposite, no custom pcb, modules including a TDA530 amplifier module joined using crimped KF2510 connectors.
All are powered from an external 5V mobile phone power bank, picture attached.
You might notice the recycled Tomtom satnav speaker.
Also made a version of the Ken KM4NFQ Mega 2650 version, with a plug on UNO type TFT, parallel rather than the SPI type which?minimises external wiring.
Both versions work very well so thank you both for for your excellent work.
