Differences Hifi shield 2 and + ?

Unread postby yvecai » Thu Jun 08, 2017 4:13 am

Everything is in the question, can somebody explain clearly?
I particularly wonder for the compatibility with the 3.5'' touchscreen.

HiFi Shield 2 has a slightly higher dynamic range (114dB vs 110dB) with analog volume control capability.
But a couple of GPIO pins conflict with 3.5inch touchscreen interface signals.

So you have to choose the HiFi Shield+ to use the 3.5" touch display.
You need a stacking header something like this.
