Kinowheels 3-Axis wireless for DJI Ronin

Project made with Quentin Boschini.

Description

Use the Kino wheels to command a DJI Ronin (tested on DJI Ronin 2, DJI Ronin S)via SBUS protocol using Arduino boards.
Transmition to the Ronin can be done via a cable or wirelessly with a main transmitter powered by a Vlock batterie and a receiver powered by the Ronin.

Hardware

• You can find all the Fritzing schematics in the repo.

Transmitter - Receiver

• 1x Arduino DUE (transmitter)
• 1x Arduino NANO (receiver)
• 2x Nrf24L01 (wireless 2,4 GHz module)
• 2x LCD 0.96' Adafruit I2C (using Adafruit SSD1306 library)
• 2x Rotary encoder SPI (for interaction with the lcd fonction, for now only modify nrf24 channel)
• 3x Potentiometer (used to amplify or reduce the kinowheel values send to the SBUS)
• 3x Toggle Switch (to invert the wheel rotation)
• 2x SN74HC logical inverter (required for transmitting SBUS signal)

Optional debug Sbus receiver

A Sbus receiver, usefull to have a direct return from a Sbus signal for debugging purpose\

• 1x Arduino UNO
• 1x LCD 0.96' Adafruit I2C
• 1x SN74HC logical inverter

Arduino Libraries

• BMC_SBUS -> https://github.com/boldstelvis/BMC_SBUS
• BMC_SBUS_DUE (just a modified version from the one bellow you can find it in the repository)
• Adafruit_SSD1306 -> download from the Arduino IDE
• Adafruit_GFX -> download from the Arduino IDE (automaticaly installed with Adafruit_SSD1306 ?)
• RF24 -> https://github.com/nRF24/RF24
• sbus-arduino (for the debug SBUS receiver) -> https://github.com/bolderflight/sbus

Future plan

• Controlling modes and profiles with external buttons or with sub menus with the LCD
• Designing new wheels more balanced, with conic shaped axis

Still work in progress, will upload tutos and photos...
