Control Zero H7 OEM - M10059

3D View

Description

The Control Zero series of flight controllers represents 3DR'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. Our journey begins with this Zero in its OEM form factor - this is a no-compromise triple IMU commercial-grade flight controller.

Design changelog

The latest revision G model includes the following enhancements to the previous versions:

• MCU power supply redesign, lower operating temperatures (5-10C reduction).
• Temperature compensated oscillator replaces traditional crystal.
• Upgraded barometer for harsh environments, high-humidity tolerant.

Rev D:

• Removed level shifting due to manufacturer decision to discontinue it on short notice. Replaced with robust ESD and current limiting protection.
• Added additional voltage rail diagnostic LEDs.
• Moved SDCARD to expose the MCU package to enable operations on higher temperature environments with external thermal solutions.
• Simplified overall electrical design with additional test points for factory quality control checks.
• The external interface remains unchanged for drop-in replacement with earlier revisions.
• All-around 3V3 logic level.

Quick start

Install the board on its carrier and connect via USB to start configuring parameters and connecting peripherals.

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. There is no need to change the bootloader if you want to flash PX4.

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

Firmware

The 3DR Control Zero is compatible with the following firmware:

ArduPilot

Bootloader now present on TELEM1 port as well.

• - compatible with all vehicle types (for rev D).

PX4

Rev G support pending.

• - compatible with all vehicle types.

Some additional resources:

• First Time Setup
• CAN Bus Setup
• UAVCAN Setup
• Advanced Configuration

Graphical pinout

The serial ports default assignment is as follows:

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

Power considerations

The board is intended to be powered either from the power 'brick' labeled as 5V_SRC in the above diagram or the VUSB pin or both; 5.25V is recommended due to protection diodes, this way you'll avoid getting low voltage warnings from the ground station software. The CZ OEM is able to provide up to 1.8A (fused) to the 5V_PRPH power domain, exceeding this current will damage the board.
