APM/PX4 CAN Expansion Module

Overview

Project Introduction:
This module is an expansion module for the CAN bus interface of the APM flight controller.
Project Functionality:
When the flight controller's interfaces are insufficient, the CAN interface of this module can be connected to the flight controller's CAN interface. The wiring of this module is the same as the wiring on the flight controller. Functionality can be enabled on the flight controller.
Project Parameters:
It can connect to a buzzer, 4 PWM outputs, an LED strip, three serial ports, two I2C ports, one SPI port, C_R connects to analog current, C_T connects to analog voltage, C-R2 is the current of the second battery if there are two batteries, BAT2 is the voltage of the second battery
