Is it possible to use the Teensy 4.1 TX pins to sink 10mA, coming from an optocoupler's LED? And doing this on all 8 TX pins?
I found a post on the forum mentioning a 4ma max current/pin, is this correct?
The TX pins are used for DMX data (250 kbps baud rate). What would be the recommanded way of avoiding the TX pins for sinking the current?
Thanks.
