SEQURE FPV Elements evaluation: H743 FC, E70 G2 ESC, M10-12 GPS & Twin ELRS RX

SEQURE is a widely known firm on the planet of FPV (First Particular person View) resulting from its wonderful pen-style soldering irons. These days, it has additionally began offering FPV drone elements for the neighborhood. On this evaluation, we can have an in depth have a look at its highly effective flight stack, GPS module, and ELRS radio receiver.

Constructing an FPV drone entails a number of steps, together with choosing elements, assembling the drone, configuring the flight controller, and establishing the FPV system. Along with these SEQURE FPV Elements, you’ll need a body, propulsion system (motors and propellers), and FPV system (VTX and digicam) to construct your drone.

The flight stack is the center of an FPV drone. It’s often put in within the heart of the body and comprises two boards: the flight controller (FC) and the ESC (electrical velocity controller).

Disclosure: I acquired these FPV elements in a evaluation collaboration with SequreMall. Though the product was free, all opinions on this article stay mine, and the sponsor didn’t affect me.

SEQURE (Guangdong Sequre Expertise Co., Ltd.) is a high-tech, revolutionary enterprise integrating digital expertise analysis and improvement and worldwide commerce, with a registered capital of 700,000 $. The corporate covers an space of 1600 sq. meters, together with 1000 sq. meters of manufacturing and analysis. Their product vary contains DIY instruments (Soldering irons, Spot Welders, Digital Screwdriver, and Tweezers), Motor drivers, Soldering equipment, FPV drone elements, and PNP and BNF FPV drones (8″ and 10″).

All of the FPV elements I acquired had been packed in a zipped electrostatic bag with the wanted equipment and wires. No person guide or wiring diagram is included.

1. SEQURE H743 flight controller for X8 FPV drones

The SEQURE H743 is a flexible flight controller constructed across the high-performance STM32H743 Arm Cortex-M7 microcontroller. It has two ESC connectors, so it might management as much as 8 motors, making it appropriate for skilled CineLifter drones. It additionally has devoted connectors for each analog and HD digital (DJI O3/Vista/Hyperlink/Walksnail) VTXs.

The equipment contains one ESC cable, two 30AWG 100mm single-head cables, ten shock-absorbing balls (5x M3*8mm and 5xM3*6.6mm), and a buzzer.

I like that the SEQURE H743 options each 30.5×30.5mm and 20x20mm mounting patterns, making it appropriate with a variety of drone frames. The FC measures 36.5*36.5*6mm and weighs virtually 8 grams. It has six UART ports for exterior elements similar to GPS, RX, or Optical circulation sensor.

It has massive solder pads with beneficiant distance between them, permitting straightforward and protected welding.

2. SEQURE E70 G2 2-8S BLHeli_32/AM32 70A ESC

This yr, BLHeli_32 stopped offering any additional assist and additional firmware upgrades, so it’s extremely welcomed that the SEQURE E70 G2 ESC additionally helps the AM32 open-source different.

Along with the ESC board, the bag contains two ESC to FC cables, 12AWG 100mm battery wires, an XT60H-M connector, a Low-ESR 35V 680UF capacitor, and 5 M3*8mm rubber grommets for a smooth mount.

As its title suggests, the SEQURE E70 can present a steady present of 70A for every motor and, for brief intervals of time, even 150A (peek present). It’s appropriate for as much as 8S LIPO batteries and appropriate with Dshot600/300/150, Oneshot, Multishot, and PWM protocols. You may go for hardwiring (soldering) with the flight controller or by means of the onboard connector. It has devoted pins for ESC telemetry. The built-in galvanometer sensor offers motor velocity, temperature, and real-time monitoring.

The motor pads are barely angled to align with the body’s arms, permitting a lot cleaner cable routing. The board measures 45.5*42.5*6mm and weighs 18 grams. It’s meant for giant, highly effective drones with solely a 30.5*30.5mm, Φ4mm/M3 mounting sample.

3. SEQURE M10-12 GNSS module for BetaFlight FPV drones

Since 2024, BetaFlight has offered virtually DJI-like fail-safe return to dwelling (RTH), which saves your drone from crashing in the midst of nowhere in case of RC sign loss.

SEQURE has three GPS modulus: M10-12, M10-18, and M10-25Q. The M10-12 is the smallest, making it appropriate for compact FPV drones. The M10-25Q is the most important and has an built-in QMC5883L compass for full INAV compatibility. The product quantity within the product title represents the scale of the ceramic antenna. An even bigger antenna means sooner and higher GNNS sign reception. All variations assist crucial satellite tv for pc positioning suppliers, together with GPS (International), GLONASS (Russia), BeiDou (China), and Galileo (Europe).

Measuring 12x16x4.5mm, the SEQURE M10-12 is as tiny as your fingernail. The module weighs solely 2.3 grams and has standing and energy LEDs. You may wire it to the flight controller with a devoted connector or solder pads (5V, TX, RX, and GND).

BetaFlight Failsafe Rescue Mode with SEQURE M10-12 GNSS

Configuring GPS Rescue mode in BetaFlight is straightforward and requires only some steps. First, it’s essential to allow the GPS characteristic within the configuration tab and set “Sensor enter” to the suitable UART port (on which the SEQURE GPS is wired). Below the GPS tab, choose the “UBLOX” protocol. If all the pieces is wired and configured appropriately, you must see a sign from the satellites.

Subsequent, navigate to the Failsafe tab within the Betaflight Configurator. Right here, for “Stage 2”, choose GPS Rescue and configure RTH velocity and altitude. If you happen to can’t see the “Failsafe” tab, make sure you’ve enabled the “Skilled Mode”.

4. SEQURE 2.4GHz Twin RX True Range ELRS receiver

SEQURE’s Twin-ELRS receiver module is offered with three antenna choices: brief (80mm), lengthy (220mm), and blended (one 80mm and one 220mm). Putting in the antennas in several positions and orientations is beneficial to reap the benefits of the DIVERSITY antenna system.

The PCB measures 23* 12.8* 5 mm and weighs 1.5 grams. It has solder pins (GND, 5V, TX, and RX) and a devoted connector for wiring with the flight controller.

This ELRS module is totally appropriate with Range radios such because the Jumper T20 GEMINI, offering essentially the most secure sign and one of the best penetration in any surroundings. This SEQURE RX is appropriate for each long-range and bando FPV drones.

The module is constructed across the ESP32-PICO-D4 MCU and the dual-frequency SX1281 RF chip. It makes use of a TCXO temperature-compensated crystal oscillator for enhanced stability. Its twin 100mW built-in energy amplifier (PA) offers the transmitter telemetry information (RSSI sign well being). It helps F1000Hz and F500Hz ultra-high refresh charges and meets the low latency necessities of racing pilots.

It comes with the “SEQURE 2.4GHz Twin RX_3.4.0” firmware model out of the field. The software program could be upgraded in UART mode (by means of FC BetaFlight) or WiFi utilizing the built-in net server.
