  • Hi, wanting to use this shield MP3 Arduino in the MIDI mode, do I do the linking SJ2 (3) MIDI-In (MIDI input signal) and SJ1 (4) GPIO1. With Arduino the signal output at the GPIO1 for the MP3 mode GPIO1 “low” and MIDI-In “high”, for the MIDI mode at the GPIO1 “high” and MIDI-In “signal”),all right! But observing the resistances R13 and R14 from 1K are not too small, if the maximum voltage tolerated by VS1053 is 3.6 V, (the output voltage from the divider is > 3.6 V), the signal “high” of Arduino is 5V?

No public wish lists :(
