I’m working on putting a 10.1" LCD (HDMI 10" LCD Screen Kit (1024x768) – Pimoroni) into its own cabinet, but I’m thinking I might not want to integrate the Pi directly into the cabinet, as I’d like to use a MiSTer instead. That would mean needing some sort of audio amp inside the cabinet, as there’d be no Picade HAT inside.
It looks like this Adafruit board would be an option: Adafruit I2S 3W Class D Amplifier Breakout - MAX98357A – Pimoroni
Can the amp be powered entirely by the 5V pin on the LCD driver board?
If so, it seems like you’d connect:
LCD Driver → DAC/Amp
5V → Vin
GND → GND
DATA → DIN
BCK → BCLK
Seems like I’m missing a pin. Is the driver board’s LCLK the word select, in which case:
LCD Driver → DAC/Amp
LCLK → LRC
Anything I’m missing? Thanks in advance!
