  • Optimised for 1S Whoops: Designed to enhance performance with the DJI O4 digital transmission system.
  • Three-in-One Integration: Combines flight controller, ESC, and ELRS 2.4G RX into a compact unit, focusing exclusively on high-quality digital FPV by eliminating analog OSD.
  • Stable HD Video Transmission: Features a newly developed BEC to ensure consistent power delivery for seamless HD performance.
  • Enhanced Overcurrent Capacity: Supports 12A continuous current and 18A peak ESC, providing robust performance for demanding flights.
  • Reliable Precision: Includes an independent 3.3V LDO design to deliver stable, interference-free power directly to the IMU for accurate control.
  • Effortless Setup: Equipped with convenient motor plugs and a SH1.0-6Pin HD digital port for a solder-free, hassle-free installation and maintenance experience.

New BEC for Stable HD Image Transmission

Digital image transmission requires higher current, and 1S whoops often fly at voltages as low as 3.3V, placing significant demands on the BEC. To meet these challenges, an advanced BEC has been developed, capable of delivering over 3A of current at ultra-low voltages down to 2.85V. This ensures stable digital image transmission even in critical situations. While flying to such low voltages isn't recommended, this innovation provides pilots with a greater chance of safely recovering from unexpected situations.

Enhanced Continuous 12A ESC

HD image transmission adds weight to 1S whoops, demanding stronger power and higher ESC overcurrent capacity. Our engineers exceeded expectations, delivering a robust ESC with 12A continuous output and 18A peak capacity on the iconic "cross" flight controller. This ensures optimal thrust-to-weight ratio, reliable performance, and worry-free high-definition flights.

Individual Power Supply for IMU

Unlike traditional shared power supply designs, the Matrix 1S 3IN1 HD FC features an independent 3.3V LDO power supply exclusively for the IMU. This innovation eliminates interference, creating a cleaner and more stable environment that enhances flight precision, improves sensitivity, and reduces the risk of performance issues—ensuring unmatched stability during every flight.

Effortless Setup and Maintenance

The Matrix 1S 3IN1 HD FC is designed to maximise your flight time by minimising setup hassle. Equipped with convenient motor plugs and a SH1.0-6Pin HD digital port, it allows for a completely solder-free installation and maintenance process. Now, you can focus more on enjoying high-definition flight experiences instead of dealing with complex tools.

Serial ELRS 2.4G RX

Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3.0 with no need to flash Betaflight flight controller firmware. Enter binding status by power on/off three times.

  • Plugin and unplug the flight controller three times;
  • Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
  • Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
  • If the receiver has a solid light, it's bound.

The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.

  • Plug in your FC to your computer, connect to ExpressLRS Configurator instead of Betaflight Configurator;
  • Choose target "BETAFPV 2.4GHz AIO RX";
  • Flash using the BetaflightPassthrough option in ExpressLRS Configurator.

How to flash firmware via Wi-Fi here.

Betaflight Firmware and CLI

Betaflight official developers recommend using version 42688 of the gyroscope, and many issues with ICM42688 have been fixed in version 4.5.0. Please learn more from version 4.5.1.

Bluejay ESC Firmware

With BB51 ESC solution, Matrix 1S 3IN1 HD Brushless Flight Controller is based on A_X_5_96_v0.19.2.hex for BB51 Bluejay firmware, it supports DSHOT300, DSHOT600, and even RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies. 

DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.

How to Use Serial Ports, Intergrated RX and VTX

UART3 is connected to the built-in serial ELRS RX. To release UART3, please remove the resistor. Additionally, this FC reserves 2 complete full-featured serial ports that can be used for external serial receivers, GPS, HD VTX, or other serial devices. You can refer to the picture below.

Runs small, rough on the inside
Color: Misty Blue, Size: X-Large, Color: Misty Blue, Size: X-Large
Basic performance half button pullover that looks great but just isn't quite worth the money. The polyester material will protect you from light rain and wick the moisture away, but everything else about it feels a little bit low rent. The plastic snaps on the collar are similar in quality to a cheap, disposable poncho. The interior is pretty scratchy and catches on the rough skin on the back of my elbow. Fit is a little snug and for 8% spandex there's just not much stretch. Misty blue color is attractive, but not enough to overcome the middling construction and build quality. Feels very similar to the underwhelming jackets I've 'earned' from my employer for meeting some sort of corporate milestone. If this were $25 I'd give it an extra star. For the list price you can find much better stuff from much better brands if you shop the sales.

Lightweight Layer That Works
Color: Navy, Size: XX-Large
This pullover has been a solid option for cooler days without feeling bulky or restrictive. The lightweight fabric is breathable and comfortable, especially for movement, and it works well both on the golf course and for casual wear. The mock neck and half-button design give it a slightly polished look, while the pockets are genuinely useful and not just decorative. It fits true to size and layers easily over a tee or under a vest. Overall, it’s a practical and comfortable piece for active or everyday wear.

Fits and looks great
Color: Black, Size: Large
This golf pullover will be great for the upcoming golf season. The fit (Large) is excellent. The sleeves may be on the long side for some, but they can easily be pushed up the arm or cuffed on the arm. The chest and shoulders fit like a tailor-made pullover. The length is shorter than a normal pullover because it is meant for golfing. So kudos here. The material seems durable and the snaps work better than buttons or a zipper. The material seems comfortable and durable. I give this pullover high marks and will get a lot of use wearing it on the course.

Comfortable, Quick Drying, but Shipping Creases Were Difficult to Remove
Color: Misty Blue, Size: Large, Color: Misty Blue, Size: Large
This is a nice looking lightweight, long sleeve casual shirt. It is made of primarily polyester with a little spandex. My husband said the shirt fit as expected and was comfortable. He noted the sleeves are a little long on him, which makes me believe it would fit a tall person nicely as my husband is of average height (5‘8“). The shirt arrived in a vacuum pack plastic bag which caused it to have significant wrinkles (see photos). I initially tried tossing it in my dryer on the “rapid refresh“ steam cycle to see if it would remove the wrinkles. The shirt, came out with virtually no change to the wrinkles,. I then tried laundering and drying it to see if that would remove the wrinkles. Again, virtually no change. Finally, I pressed the shirt as per the care label. I mostly pressed it from the wrong side, or, in areas where that wasn’t feasible, I used a press cloth. I ended up using the “silk” setting on my iron because the synthetic setting would not remove the wrinkles. After pressing, the shirt, looks nice. I’ve included the one picture of it after I pressed it. I’m hoping that the shirt, will be as resistant to wrinkling as it was to having the wrinkles removed! Also, I noticed that the shirt seems to be well constructed. I’ve included one photo I took while pressing it from the wrong side that shows how nice the seams look. Pros: Comfortable Fits as expected. Attractive color Quality construction Launders nicely Dries quickly Cons: Shipping wrinkles resistant to removal On the upper end of price range for comparable shirts

Comfortable and stylish
I wanted something to wear in warmer weather that was full length and offered some protection against the sun when working and playing outdoors (I'm a ginger so this is a real problem for or else I turn into a lobster). I had gotten some very nice slacks that I can wear and still look professional, and this shirt complements those very well. This is a nice, loose-fitting long-sleeved shirt that you can wear pretty much anywhere outdoors and is perfect for golf or frisbee or even just corporate picnics. It's not going to overheat you if you wear this in the sun in summertime as it's loose enough that air still flows. It's only SPF 30, so I guess if you need more than that you'll either need lotion or another shirt? It's machine washable and as my pictures show I washed mine and all the wrinkles promptly disappeared, which I though was a hug win. I ordered the size I normally wear (XL) and what the sizing charts suggested and this does fit as expected. The fabric feels a little stretchy, but it's not like a pair of cotton sweatpants or anything, just enough give to allow plenty of comfort while moving around doing normal things. For less than $50 I have a nice, business casual pullover I can wear lots of places and feel dressed up enough to fit in.
