Product Overview
Product description
The new generation of the EA-30XP comes with leading binocular vision system and ultra-low terrain follow
technology, allowing the drone to automatically avoid obstacles in fertile fields, hilly and mountainous
terrains. The mist nozzle produces droplets to penetrate various kinds of crops. For spreading operations,
users can purchase the optional spread package to transform the drone into spread configuration. The drone
has a protection rating of IP67 (IP66 for battery), which contributes to easier cleaning and higher efficiency
of operation.
Feature highlights
⚫Consisting of the self-developed flight controller - eaPro and uniCom3.0, EA-30XP highly integrates flight
control, environment perception and data transmission, allowing users to check key data from plot
surveying to operations through one touch.
⚫The new power system has increased the load capacity by 12%, and the optimized ESC layout has
improved its anti-interference ability to ensure stable and reliable flight.
⚫The integrated spray tank is with a capacity of up to 32L. When switching to spreader mode, the pump
and flow meter can be removed with the whole spray tank to reduce the invalid load.
⚫The updated spreading system is with a spread capacity of 40L, and can be changed quickly with the
spraying system. Equipped with the integrated intelligent weighing system and the blade stirrer, the drone
can accurately discharge and avoid getting stuck. The maximum opening valve has been increased by 33%,
improving the overall spreading efficiency by 30%.
⚫The integrated mist spraying system - CCMS-L20000 has effectively reduced cable wear, enhanced the seal
structure, and reduced nozzle jam. It can produce droplets to penetrate crops with size ranging from 10
to 300 microns, which reduces drift, increases the pesticide amount on the back of the leaves, improves
utilization efficiency of pesticides, and ensures the effectiveness of agricultural protection for all types of
crops.
⚫The updated FPV high-definition camera enables 120° vertical rotation and 130° ultra-wide viewing angle.
Its high-stable PTZ guarantees no sense of delay in the video screen. Combined with AR auxiliary function,
landscape and tree-shaped obstacles can be displayed at decimeter level, making the flight and surveying
more convenient, and manual operation more friendly.
⚫The new function of three links in one enables fast connection, and instant flight when you turn on the
devices. Data transmission link combined with dual-card link, guarantees no fear of signal blockage and
weak network.
⚫The mini magnetic surveying tool - EA-SUT 4.0 uses an integrated antenna to receive accurate position
information. Equipped with the magnetic base, the surveying tool can be absorbed to the remote
controller support, making the installation easy and convenient. It can also be connected to the remote
controller quickly and stably through serial interface.

5
⚫With built-in large-capacity battery, the local base station - EA-BAS 3.0 can operate continuously for 20
hours. It can work even longer with the external power supply through the charging socket on the back.
Its display panel is concise and clear, and has the cloud base station alignment function: the base station
can be placed arbitrarily before operation without affecting the operation accuracy.
⚫The drone can fly as low as 0.7m from the canopy, shortening the droplet settling distance, significantly
reducing evaporation and drift, enhancing the penetration of the liquid, and ensuring the effectiveness of
agricultural protection for all types of crops.
⚫The integrated night flight system - EAV-NTL 3.0 is waterproof and heat resistant. The irradiated area is as
much as 400 square meters, and the uniformity of light is increased by 10%, which significantly enhances
the ability of autonomous terrain following at night in hilly and mountainous areas.
⚫The A-B route function enables users to record points A and B in the plot and adjust the parameters
manually to plan the route.
⚫The intelligent resuming flight function optimizes the flight path automatically, effectively reducing full-
load and no-load flight time, and increasing operating efficiency by up to 30%.
