Description

The Control Zero series of flight controllers represents mRo's commitment to continuous improvement. Our goal with this series was to take every lesson learned from our +10 years of flight controller design and make the best pro-consumer and commercial flight controller on the market. With the Classic form factor, we try to still support the tried and tested Pixhawk 1 form factor and connector set, while bringing a modern feature and sensor set to the table.

About IO coprocessors

Historically, microcontrollers mounted on Autopilots didn't have enough resources to handle the requirements that industry was demanding. Usually, the features needed to keep up with the trends, pushed manufacturers to add IO coprocessors to increase the number of available timers to generate and decode PWM signals and additional IO Pins. The coprocessor in these hardware architectures is usually connected via a single serial port, reducing the amount of data available in time and introducing more points of failure. However, later generations of hardware have increased IO pin density, timers and reduced size factor, among other enhancements. Additionally, a special benefit also stands out for our design principles, and it is the higher amount and more sophisticated DMAs that work really well with peripherals, transferring high amounts of data and decreasing CPU usage. Besides, we are transitioning from a single MCU architecture to more distributed systems thanks to DroneCAN and Ethernet connectivity (coming soon).

Quick start

The board comes with Ardupilot stable pre-installed from factory. However, the bootloader provides an interoperation layer with PX4 as well, so QGC will be able to detect it and load firmware adequately.

We encourage all customers to run the latest stable version available from your preferred flight stack.

Firmware

The mRo Control Classic is compatible with the following firmware:

ArduPilot

  • APrelease - compatible with all vehicle types.

PX4

Warning

PX4 support for this board is PENDING!.

  • Releases - compatible with all vehicle types.

Some additional resources:

Graphical pinout

The serial ports default assignment is as follows:

Serial Port name
USART2 TELEM1
USART3 TELEM2
USART4 GPS1
USART7 GPS2
USART8 FrSKY serial

Custom builds may be needed if you want to change default functionality for UART/SPI 6, this depends on the selected flight stack firmware.
