Empower your drone with precision navigation using the Holybro H-Flow - a compact, all-in-one optical flow and distance sensor module built for professional UAV developers and demanding industrial applications. This advanced module integrates a PixArt PAA3905E1 optical flow sensor, a Broadcom AFBR-S50LV85D LiDAR rangefinder, and an InvenSense ICM-42688-P 6-axis IMU into a single lightweight unit. The result is high-accuracy motion tracking and altitude measurement for stable flight control, even where GPS might be unavailable. An onboard infrared LED further enhances performance by illuminating surfaces in low-light conditions, ensuring reliable optical flow data during indoor or night operations. If you're building autonomous drones for inspection, mapping, or any other mission-critical tasks, the H-Flow delivers the robust sensor data and easy integration you need for success.

Key Features & Benefits

  • Integrated Optical Flow, Rangefinder & IMU: Combines three sensors in one compact module, reducing weight and wiring while simplifying installation, giving you more space and payload capacity for other critical components.
  • PixArt Optical Flow Sensor - Precise Motion Tracking: Offers high-precision optical flow data for accurate horizontal motion tracking, functioning in very low light thanks to the onboard IR LED. Your drone can maintain stable positioning and smooth navigation in dimly lit warehouses or at dusk.
  • Broadcom ToF Rangefinder - Reliable Distance Measurement: Delivers accurate range readings from as close as 80 mm up to 30 meters, enabling low-altitude hovering or high-ceiling indoor flights. Engineered to work under direct sunlight and on all types of surfaces, it ensures consistent performance indoors and outdoors.
  • Infrared LED for Low-Light Performance: Actively illuminates the ground for the optical flow camera, significantly improving feature tracking in darkness. This means your drone can navigate in GPS-denied, low-light environments without losing positional accuracy.
  • DroneCAN Protocol - High-Speed, Robust Communication: Leverages the DroneCAN protocol over its CAN bus interface, delivering reliable, high-bandwidth data transmission between the sensor and flight controller. Ideal for industrial UAV fleets and complex onboard networks.
  • Pixhawk-Standard CAN Connector - Plug & Play Integration: Features a Pixhawk-standard 4-pin JST-GH CAN connector for effortless installation with a Pixhawk or any DroneCAN-compatible autopilot. Software-controlled CAN termination is included, and firmware updates can be performed easily through DroneCAN tools.

Built for Professional & Industrial UAV Applications

Engineered with professional drone developers in mind, the Holybro H-Flow brings industrial-grade sensor performance to your UAV projects. Its lightweight design adds minimal payload, making it ideal for agile drones and long-endurance flights. Whether navigating indoors, operating in tight urban spaces, or under dense foliage, the H-Flow module empowers your flight controller to hold position with centimeter-level stability and follow terrain or maintain altitude with confidence. From precision agriculture to mapping, security, and industrial inspection, the H-Flow module enhances navigation accuracy and safety, letting your drone fly smarter and more securely.

With the Holybro H-Flow optical flow and distance sensor module on board, you get a plug-and-play navigation solution that blends technical precision with proven reliability - exactly what professional UAV applications demand. Elevate your drone's capabilities and experience more stable, intelligent, and autonomous flights on every mission.

Game Changer for Coffee Lovers
Color: Storage Cover Black, Size: Rechargeable
I purchased the Circle Joy Rechargeable frother mostly because of the price. The frothy-whipped cream is a treat on the weekends, and the last hand frother I purchased zapped out. WoW - this one is amazing! The last one I had was battery operated, and wasn't as fast as this one. I now use it everyday because it works so quickly. It comes with a "lid" for the blender part, so I can toss in my briefcase. Love that recharges quickly so its ready when I am. Great price, easy to use, looks sleek, and tiny enough to take with you. LOVE, FiVE Stars

Great for short term
Color: Storage Cover Black, Size: Rechargeable
Works great when it works.... But I've bought three this year and two of them just unexpectedly died with no logical reason. Giving up and trying a new brand for my protein coffee drinks. *Edit....after original review the seller offered a refund and apologized for the issues I had. Bumping up my rating for proactive customer service and trying to make things right.

Great buy!
Color: Storage Cover Black, Size: Rechargeable
Great product. I'm glad I bought this to replace my old, cheap one that I got from Ikea. I like that it has double whisk as it does froth my liquids really well. I like the speed of it and it's easy to use and wash. The battery life is pretty long as well. I haven't charged it since I got it.

Pretty darn good frother...
Color: Storage Cover Black, Size: Rechargeable
This is a pretty darn good frother/whisk, which we use primarily for mixing Crystal Light and LMNT drinks. It holds a charge for a long time and it is easy to recharge with the USB-C port and cable. My only complaint is that you must hold the power button continuously while operating it which is challenging to do using tall cups. It would be much better if is was a two stage on-off switch and had a longer wand, which isn't as long as it could be. But the unit is lightweight, easy to use and very versatile. Overall, I would buy it again.

Works great!
Color: Storage Cover Black, Size: Rechargeable
I bought this because the frother I had was very weak. Even with new batteries, it just never had much oomph. I liked the idea of it being rechargeable and no more batteries! I expected to have to charge it when it came, but it had full power. I have used it every day since it arrived, and it hasn't slowed down a bit. It is easy to use, just pushing down with my thumb on the top. I also love that it has a lid/case. When I bring it on a trip it is fully protected from damage. I highly recommend this frother. It is the best one I have had - and I have had quite a few.
