Hi, I would like to know what pins are used by the Audio Amp Shim (Audio Amp SHIM (3W Mono Amp) – Pimoroni).
Usually the Pimoroni products are conveniently added to the pinout.xyz but I could not find this one.
The page on the shop tries to describe which pins are used but I feel confused after reading it (at some point it says the installer configures I2S audio and SPI, then says to add
dtoverlay=hifiberry-dac gpio=25=op,dh and in the notes it says Audio Amp SHIM uses GPIO 18, 19, and 21 (as well as 3.3v, 5v and various Grounds)).
Could someone with that knowledge (cough @gadgetoid /cough) add the entry on pinout.xyz please?
Thanks a lot.
