explain ELRS and related things like im dumb.
these are my questions:
do you need a separate flight computer when using an ELRS module with pwm like this one?
if the answer above is yes then can i use an esp32?
if the answer is no, how does it work and do i just need to connect power supply, servos, motor, ect.
how does betaflight work? (i have only ever used Arduino ide)
this is a dumb question but can someone explain the channels and stuff.
