Foxeer UAV electronics: Razer and Predator FPV cameras, Reaper VTX, and Lollipop antennas

Foxeer equipment identification, camera form-factors, and optical mounting standards

Shenzhen Foxeer Technology Co., Ltd.

(founded in 2014; headquartered in Longgang District, Shenzhen, Guangdong Province, China) develops and manufactures high-performance optical cameras, long-range 5.8GHz video transmitters, circular polarized antennas, and flight stack electronics for unmanned aerial vehicles (UAVs) and FPV racing

platforms.

Equipment selection centers on camera physical mounting form factors. Standard Mini dimensions correspond to a 22mm width (22x22mm), Micro designates a 19mm enclosure (19x19mm), and Nano features a compact 14mm profile (14x14mm).

Modular metal and composite brackets adapt Nano bodies to Micro or Mini drone frames seamlessly. Optical lens mounts are standardized around industrial metric threads, using M8/M10 threads on micro-sensors and heavy-duty M12 barrels on wide-aperture night lenses.

When requesting replacement units or system configurations, providing the part number, lens focal length (1.7mm, 1.8mm, 2.1mm, 2.5mm), optical sensor format (1/3-inch CMOS or 1/2-inch Starlight), and OSD control protocol guarantees straightforward compatibility across existing airframe assemblies.

Razer, Predator, and T-Rex FPV camera series: dynamic range and response latency

Foxeer Razer, Predator, and T-Rex optical cameras represent purpose-built imaging sensors tailored for competition drone racing, tactical surveillance, and aerial inspection.

The Razer line delivers crisp 1200TVL resolution with natural color balance and minimal latency, powered directly from 4.5V to 25V DC flight battery taps.

The Predator V5 series features hardware-accelerated Super WDR processing.

Unlike standard sensors that wash out when facing direct horizon glare, the Predator dynamically balances exposure across bright clouds and shadowed ground clutter, maintaining continuous obstacle visibility at high transit speeds.

Flagship T-Rex Micro cameras deliver ultra-high 1500TVL analog clarity using a dedicated 2-megapixel high-speed sensor.

Featuring a 6-millisecond minimal latency pipeline and proprietary K-shutter technology, the T-Rex eliminates vibration-induced jello distortion, rendering thin wires and branches with exceptional sharpness.

Cat 3 and Toothless 2 low-light FPV camera modules: Starlight sensor architectures

For night inspections, twilight missions, and low-visibility weather operations, Foxeer manufactures specialized Cat 3 Starlight and Toothless 2 Pro cameras.

These units integrate large-format 1/2-inch CMOS sensors with substantial individual pixel surface area compared to ordinary 1/3-inch or 1/4-inch chips.

The Cat 3 Starlight architecture achieves 0.00001 Lux ultra-low-light sensitivity, allowing drone operators to navigate using natural moonlight or distant ambient reflections without revealing active infrared illuminators or power-draining floodlights.

Multi-coated anti-reflective glass lenses minimize flare from industrial security lamps.

Toothless 2 Pro cameras provide all-weather capability, preserving 1200TVL high-contrast detail under intense daylight and deep shadows alike.

Integrated OSD menus allow operators to adjust auto-switching monochrome day/night thresholds, 3D digital noise reduction (DNR), and color saturation for mission-specific atmospheric conditions.

Reaper Extreme and Infinity 5.8GHz video transmitters: thermal design and range

Foxeer Reaper Extreme (2.5W / 3W) and Reaper Infinity (up to 5W) video transmitters are engineered for long-range telemetry and operations through heavy industrial RF interference. The modules broadcast across the 5.8GHz band over 40 standard channels across bands A, B, E, F, and RaceBand.

Managing high RF output demands active thermal dissipation. Reaper transmitters feature CNC-machined aviation aluminum heat sinks with direct thermal compound coupling to power amplifier dies, preventing power sag and thermal throttling during extended ground idling or high-power flight phases.

A low-power Pit Mode (<1mW) allows frequency verification and setup on the flight line without disrupting adjacent channels.

Real-time channel and power adjustments are managed automatically via the flight controller using the IRC Tramp serial protocol, enabling pilot adjustment directly from radio switches.

Foxeer F722 flight controllers and Reaper 4-in-1 multi-channel speed controllers

Flight stabilization and autonomous control across Foxeer platforms rely on STM32F722 32-bit microcontrollers. Operating at 216MHz clock speeds, the processor executes gyro digital filtering and PID calculations concurrently at loop rates up to 8kHz without software jitter.

F722 V2 and V4 boards incorporate low-noise vibration-isolated gyroscopes, precision barometers for altitude hold, and onboard Blackbox Flash memory for flight logging.

Dual switching BEC rails supply clean 5V/3A for GPS/receivers and filtered 10V/2.5A power for high-power video transmitters, immune to battery voltage sag.

Complementing the flight computers, Reaper 65A and 128K 4-in-1 ESCs fit standard 30.5x30.5mm mounting patterns.

Utilizing low-resistance MOSFETs on multi-layer heavy copper PCBs, they withstand 75A burst currents per motor up to 8S LiPo (34V) inputs with BLHeli_32 firmware and bidirectional DShot RPM telemetry.

Lollipop 4 and Echo 5.8GHz circular polarized antennas: radiation and ruggedness

Wireless video range and link stability depend heavily on antenna matching between transmitter and receiver. Foxeer Lollipop 4 antennas set industry standards with balanced circular polarization (RHCP and LHCP options) and axial ratios strictly approaching an ideal 1.0 spherical pattern.

Circular polarization rejects multipath reflections from concrete structures, metal hangars, and ground planes: upon reflection, wave rotation reverses, and the matched antenna suppresses the reflected wave, eliminating video tear and interference bands during low-altitude maneuvering.

Lollipop 4 radomes are formed from impact-modified polycarbonate ultrasonically sealed against water and vibration, shielding microstrip radiators during hard landings. Available with SMA, RP-SMA, U.FL, and MMCX terminations, they suit diverse industrial airframe layouts.

u-blox M10Q GNSS navigation modules and ExpressLRS long-range telemetry links

For autonomous waypoint navigation, position hold, and automated Return-to-Home fail-safes, Foxeer produces M10Q 180 and 250 GNSS modules powered by the 10th-generation u-blox M10 satellite platform.

The M10 engine tracks GPS, GLONASS, Galileo, and BeiDou constellations concurrently. With -167dBm receiver sensitivity and tuned ceramic patch antennas, the module acquires position locks within seconds from cold boot.

An onboard QMC5883L 3-axis digital compass maintains heading accuracy in windy conditions.

Radio control links are established via Foxeer ExpressLRS 2.4GHz and 915MHz receivers. The open-source ELRS protocol delivers packet refresh rates up to 1000Hz, ensuring instant control response and interference immunity in dense RF zones.

True Diversity dual-transceiver architectures guarantee solid link margins regardless of airframe attitude.

Video link diagnostics, transient filter installation, and operational maintenance

Reliable operation of high-power UAV electronics requires strict wiring guidelines. Installing low-ESR electrolytic capacitors (470–1000µF, 35–50V) across primary battery terminals is mandatory to suppress inductive voltage spikes during active motor braking.

For FPV cameras, single-point ground wiring is essential: video ground and power ground must return directly to the dedicated camera ground pad on the flight controller, preventing ground loops and horizontal motor noise lines on pilot monitors.

We supply genuine Foxeer cameras, video transmitters, flight controllers, and antennas to industrial drone manufacturers, research facilities, and service operations globally, complete with manufacturer technical documentation and rapid international shipping.
