MEPS SZ F7 Mini: Small and versatile F722 flight controller

F722 flight controllers just like the MEPS SZ F7 Mini discover purposes throughout varied FPV drone platforms, from racing and freestyle quadcopters to skilled aerial cinematography rigs—the exact flight management, superior options, scalability, and configurability swimsuit novice pilots and seasoned professionals.

The flight controller (FC) is a vital element of an FPV drone answerable for controlling and stabilizing the plane throughout flight. It acts because the mind of the drone, processing sensor knowledge, receiving consumer inputs and adjusting the motors to keep up stability and management. FCs typically provide varied flight modes comparable to stabilized mode, acro mode, or GPS-assisted modes, permitting pilots to change between totally different flight traits and behaviors. Moreover, flight controllers could assist further options like OSD (On-Display Show), black field recording, voltage monitoring, and telemetry, enhancing the pilot’s situational consciousness.

The distinction between “NormalAnalog” and “HD digital” flight controllers is the presence of a devoted 6pin connector that’s suitable with DJI digital VTXs (Air Unit, O3 AU, Caddx Vista, and RunCam Hyperlink Wasp). The MEPS SZ F7 Mini FC has an onboard 10V/2A BEC (voltage regulator, aka Battery Elimination Circuit) to energy the digital VTX.

MEPS SZ F7 Mini FC key options

• [Smaller Shape and Lighter Weight] It takes up much less area and provides much less weight to the drone, which may enhance its total efficiency and maneuverability.
• [Faster Calculation and Stable Operation] Boasting quicker calculations, the flight controller can exactly modify the drone’s flight path in real-time.
• [Plug-in-Play DJI HD VTX Support] With plug-in-play compatibility, you may simply stream high-quality video out of your drone with out the necessity for extra wiring or setup.
• [Precise and Rigorous PCB Layout] Clear interface format to attenuate wiring difficulties and electrical interference to enhance sign transmission.
• [Integrated 5V/2A 10V/2A dual BEC] Make sure that the drone’s electronics obtain a secure and constant energy supply, bettering efficiency and lowering the chance of element failure.

MEPS Area F7 Mini assessment

Disclosure: I obtained this digital flight controller for a product assessment collaboration with MEPS. Though the FC was supplied free of charge, all opinions on this article stay mine, and the sponsor didn’t affect me. They didn’t have any particular necessities about learn how to write my assessment or entry to it prior publishing.

The SZ Mini F7 flight controller is available in a cardboard field with a DJI Air Unit cable, two sorts of ESC cables, and two units of silicone grommets (peak of 4 and seven mm). One of many ESC cables has two 8-pin connectors (meant for MEPS ESCs), and the second cable has just one connector, which provides customization flexibility with an 8 or 10-pin plug.

At a look

The FC board relies on an STM32F22 CPU and measures 37x37x8mm. It has 20x20mm mounting patterns and is appropriate for two.5-5″ FPV drones. USB Kind-C port, ESC connector, Digital VTX port, boot button, and all of the soldering pads are on high of the flight controller. It has 5 UART ports, and devoted Buzzer, and LED pads. For GPS modules, there’s a group of 6 pins (GND, 5V, RX3, TX3, SDA, and SCL) subsequent to the Kind-C port. It has 10V and 5V pads for powering the VTX and different exterior modules. On the up/left nook, a gaggle of three pads named “VTX change” permits handy management of the analog FPV transmitter, stopping overheating throughout bench operations.

Normally, an arrow on high of the FC ought to point out the set up orientation on the body. MEPS made this mark on the underside of the FC, and isn’t seen through the set up.

By default, the flight controller comes with BetaFlight V4.3.1 – Goal TMOTORF7. Many voices say that MEPS is expounded to T-MOTOR, a well-established brushless motor firm, however MEPS by no means confirmed this rumor. Utilizing the identical software program signifies that these two firms are cooperating by some means. After I did a configuration backup, I up to date the firmware to the most recent v4.2.2.

The 16MB BlackBox lets pilots file and retailer flight knowledge for additional evaluation and fine-tuning.

I matched the SZ MINI F7 in a 5″ freestyle body with an ELRS radio receiver, Walksnail Avatar HD Professional FPV package, MEPS Area SZ 45A ESC and SZ 2306 KV1750 motors. Check movies shall be added to my assessment after I end the construct.

Pricing, availability, and different choices

The SZ Mini F7 is priced at $52.9 on MEPS’ web site. This value consists of ESC and DJI VTX cables. For those who desire the 30x30mm mounting sample, MEPS has two different flight controllers priced at US$50.9.
