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.

Safe, Comfortable, and Eco-Friendly Summer Sandals for Kids
Searching for the perfect pair of summer sandals for my child can often feel like a daunting task, but the Swalker Children's Soft Jelly Sandals have truly exceeded my expectations in every way. First and foremost, safety is paramount when it comes to children's footwear, and these sandals deliver on all fronts. The closed-toe design provides ample protection against stubbed toes and sharp objects, giving me peace of mind as my little one explores the outdoors. Additionally, the anti-slip sole offers excellent traction on various surfaces, preventing slips and falls even on wet or uneven terrain. Comfort is another crucial factor, especially during long days of play. These sandals feature a soft jelly material that is gentle on my child's feet, eliminating any discomfort or rubbing that can often accompany other types of shoes. The easy-wear design allows my child to slip them on and off effortlessly, promoting independence and convenience for both of us. What sets these sandals apart is their eco-friendly construction. Made from recyclable materials, they not only provide exceptional quality but also contribute to a more sustainable future for our planet—a feature that I greatly appreciate as a conscious consumer and parent. Overall, the Swalker Children's Soft Jelly Sandals are a summer staple for any parent looking to prioritize safety, comfort, and sustainability for their child. With their durable construction and thoughtful design, they have quickly become my go-to choice for warm-weather adventures.

Super soft and adorable!
Size: 9 Toddler, Color: Macaroon
Bought these shoes for my daughter as an alternative to the classic jellies! The are butter soft! She’s been wearing them consistently for weeks now and not a single blister as formed. (Unlike when she wore the classic style ones) I’m even buying my niece a pair for her birthday because she is now jealous! The color is perfect for any outfit or occasion. They can be dressed up or down which makes them the ideal shoe! And of course super easy to clean which is of course a major factor in kids’ shoes!

LOVE these shoes
Size: 8 Toddler, Color: Macaroon
Absoultely LOVE these! So easy to wear for my 3 year old and put on. They are sturdy and could be rinsed off. They were very comfortable for her and left no marks on her skin. Warning to parents, if your kid steps on your foot it hurts like hell because they are like spikes under the shoe. GREAT for traction and running, but man it hurts. I will purchase more next summer. Great price, great fit, and lightweight.

Cute but run BIG!
Size: 8 Toddler, Color: Macaroon
I can't get the jellies from Children's Place anymore. They are causing blisters. Wanted to try these but boy, they run HUGE. My daughters sneakers are Toddler sz 8. They are starting to get tight. So got a 9 in these. WAY big all around. So got an 8. Still, too big but will save those for next Summer. Would try a 7 but the price rose. Seem soft though and I like the brown color! Would recommend but sizing is difficult. Not just in length but all around they are bigger.
