OpenLRS Receiver integrated Multicopter controller for the simplest multicopter experience

OpenLRS Rx v2 Multi is an RC receiver with integrated Gyroscope(ITG3205) and Accelerometer(ADXL345) sensors.
You don't need an extra controller or cabling for flying with your multicopter frame.

The board based on OpenLRS v2 Receiver design. This design supports all hardware PWM pinouts of Atmega328P and I2C pins for sensors. This means, you can load all Atmega328 based multicopter codes into the receiver.

It's default firmware is modified MultiWii v1.9 and you can plug and fly with it without any extra firmware or hardware. You only need to configure it with MultiWii configurator software. Please visit multiwii forums and pages for detailed information about MultiWii. 

This is our first outdoor flight video with default firmware. PID values and everything was default.

And indoor flight
