Hi,
I have an audio project with a small D class amp and some small speakers. The while thing runs fine when I power the Teensy 4 from a single lipo 3.7 volts and I power the amplifier separately from another battery.
However, when I power them both from the same breadboard rails, which is connected to the lipo battery, and I turn the volume up, it begins to stutter and Teensy shuts down and reboots itself as soon as I turn the volume down again.
I guess this is normal since the docs say Teensy can only power up to 250mA of additional circuitry.
My question is: how would you power amps and other power hungry devices from the same power source as the Teensy? And also I guess: why can Teensy only power op to 250mA off additional circuitry?
