- is there a schematic of the T1X4 amplifier board avialble?
- can the PWD-Connector be used to power peripherel devices (eg. a freedsp)?
- if yes - how mutch current can be drawn?
- where ist the best place to acces the mute-pin of the TC2050. (i like to control him via a gpio-pin of the DSP)
We have added the schematic here now:
PWD of T1x4 is a 5V logic input or switch connection, it's open drain input with 10kohm resistor pull up to 5V. So it's not output as you thought.
About the mute pins, we already use a reset chip U5 to control, so if you want to use it, remove the U5 is necessary.
