# mRo Control Zero F7 Flight Controller

注意

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer (opens new window) for hardware support or compliance issues.

The mRo Control Zero F7® is a new flight controller from mRo.

mRo Control Zero F7

It is a no-compromise triple IMU commercial grade flight controller. It includes 8x PWM outputs (DShot capable), 3x IMUs, 1x Magnetometer, 1x Barometric Pressure Sensor (Altimeter), 6x UART, and SD Card, all packed into a 32mm x 20mm PCB. The PWMs are bidirectional, EMI protected, and level shifted to 5V logic levels. All accessed using front and rear 30pin Molex PicoClasp connectors. A durable plastic case, conformal board coating, and optional temperature calibration included.

提示

Note This flight controller is manufacturer supported.

提示

Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.

To build PX4 for this target:

make mro_ctrl-zero-f7

# Debug Ports

# Console Port

The PX4 System Console runs on USART7 using the pins listed below. This is a standard serial pinout, designed to connect to a 3.3V FTDI (opens new window) cable (5V tolerant).

mRo control zero f7 FTDI
17 USART7 Tx 5
19 USART7 Rx 4
6 USART21 GND 1

# SWD Port

The SWD port (JTAG) for FMU debugging is a TC2030 debug connector, as shown below.

mro swd port

You can use the Tag Connect (opens new window) cable TC2030 IDC NL (opens new window) below (with associated retaining clip (opens new window)) to attach to either a BlackMagic probe or a ST-LINK V2 debugger.

tc2030 idc nl cable

There is also an ARM20-CTX 20-Pin to TC2030-IDC adapter (opens new window) that can be used with other debug probes.
