Holybro Pixhawk 4 Mini Flight Controller for PX4/ArduPilot
Latest official Pixhawk design.
Full featured FMUv5 F7 flight controller: dual IMU, 5 UARTs, 11 PWM, 2x I2C ports, 3x SPI buses, 1 CAN.
Faster MCU: 216MHz Cortex®-M7 (Pixhawk 3 was 180MHz, Pixhawk 2.1 was 168 MHz), fully addressable 2MB memory and 512KB RAM.
Excellent build quality: aluminum enclosure, Dronecode connectors and pinout, and top quality components (no need to wait for IMU heating)
The Pixhawk® 4 Mini is the latest official autopilot in the Pixhawk® family. It is an F7 generation flight controller compliant with the Dronecode PX4 FMUv5 reference flight controller Design, meaning the Pixhawk® 4 Mini features Dronecode compliant pinout connectors and power supply design, making it safe to use with Dronecode standard hardware sold by reputable drone equipment manufacturers.
Tom’s take: “It’s an official release hardware in the Pixhawk family, that follows Dronecode standards. It provides the reliability and performance you expect for your unmanned vehicle. With the aluminum case, this thing looks and feels amazing. This is the new flagship ArduPilot compatible autopilot from Holybro you will want for 2019.”
Craft and Theory is focused on quality hardware that is compatible with ArduPilot and works from the start. We try our best to accompany you in your build (via our forum, by email or phone) and can assure you that you will save a lot of time and frustration when you buy our products for your ArduPilot powered vehicle. We’re engineers with a passion for drones and all things autonomous.
Pixhawk® 4 Mini
Designed by Holybro, quality drone electronics manufacturer, in partnership the makers of the original Pixhawk®, now Auterion. The Pixhawk® 4 Mini is an aluminum clad full featured flight controller that is the latest iteration in the Pixhawk family. It is compact and rugged, yet very pleasant to the eye. It uses high quality electronic components and connectors including the core interfaces used in modern unmanned vehicles. It is fully supported by ArduPilot

This is why you will want to upgrade to the Pixhawk® 4 Mini:
STM32F765, 32 Bit Arm® Cortex®-M7, 216MHz, 2MB memory, 512KB RAM. More processing power and memory for smoother flights and more room for new firmware functions.
A REALLY GREAT design with an aluminum case and three LEDs that make it one of the best looking drone flight controller on the market today.
The latest on-board sensor technology from Bosch® and InvenSense® that provide low noise and high precision such that no IMU heating is required. ArduPilot makes full use of the multiple sensors for redundancy and improved accuracy.

ArduPilot on Pixhawk® 4 mini Benefits
- ChibiOS real-time operating system
- DShot1200 protocol available for the fastest ESC response
- ESC telemetry enabling motor feedback, current and ESC temperature monitoring
- Ardupilot’s advanced pin control code allows:
- 11 PWM outputs instead of 8 PWM
- Native SBUS input on “PPM” pin
- Port labeled “RCIN” can be used as an extra standard serial port
Tridge, one of the ArduPilot project leaders, said on a recent Ardupilot partner call that he recommends the Pixhawk® 4 Mini as one of the quality autopilots available now and that it should make any user happy. This is one of the most recent Chibios hardware ports that Tridge has worked on and he said he was excited to see it released.

Power Management Board
PCB Current: 120A continuous
UBEC Current: 3A Max
Power input: DC 7V~42V(2S~10S)
Power output: DC 5.1V~5.3V
Mounting hole: 30.5mm*30.5mm
The Power Management Board (PMB) serves the purpose of a power module as well as a
power distribution board. In addition to providing regulated power to Pixhawk 4 Mini and
the ESCs, it sends information to the autopilot about the battery’s voltage and current draw.
To power the Pixhawk 4 Mini, connect the output of the PMB to the POWER port of the
Pixhawk 4 Mini using a 6-wire cable. The connections of the PMB, including power
supply and signal connections to the ESCs and servos, are explained in the image and
Only one ESC and one servo are illustrated. For multiple ESCs and servos, repeat the pattern on the other MAIN OUT pins.
