So being new to this hobby it can be a little daunting when trying to figure out what does what in terms of I/O on a FC. Just trying to wrap my head around this so I know what I need in order to build a project.
Analog vs. Digital connections. What are they?
PWM - pulse width modulation - can be used for... connecting an ESC which connects to a motor. Anything else?
CAN - a bus that allows you to connect a CAN based ESC or AQ PDB. Anything else?
GPIOs - not sure what they are used for?
i2c - what is it used for?
SPI - what is it used for?
UART - what is it used for? - Bluetooth telemetry module with Kissys expansion module.
Telemetry connections... Radio Recievers/Satellites, FPV TX/RX, etc.
