Maybe you remember, I released OpenLRS Opensource RC radio system in this summer and promised "you can use our receivers as multicopter controller"
I'm glad to share our new code implementation for MultiWii.
We added OpenLRS tab into MultiWii 1.9 firmware and replaced 10-15 lines into the original code for radio system integration. Then you dont need an extra controller board just connect your OpenLRS radio receiver and sensors for flying :)
OpenLRS Rx v2 boards supporting all(6) hardware PWM channels of Atmega328P. You can use most of arduino based multicopter controller firmwares with X,+,Y,6Y,Hexa or Octa frames.
As you can see on below, we are using only radio receiver and sensors (ADXL435 + ITG3205 breakouts) for this flight.
ESCs directly connected to OpenLRS receiver. I used our sensor breakout boards, because of stackable board design. We can plug all(acc,gyro, pressure, magnetic) sensors with one 4 pin header in 15x15x8mm space. ITG3200 board under the ADXL345 board in this photo.
I used unpopulated controller board as base plate, this is why everything looking in red :)
I used CopterFrame.com's GrassHopper Basic frame. Ozan(owner of copterframes.com) designed this revolutionary frame for durability and camera mounting without propeller perspective. It's only 3 boom quadrocopter frame, simple like our controller concept :)
