Tarot OSD video overlay system GPS TL300L Tarot 250
Review of OSD
Synopsis: TAROT OSD mini perfect for 250/300 quadcopter size,
allows you to configure directly on your monitor/goggle. It is based off the Remzibi OSD,
intended for a racing quad, but can be used on any FPV models. Uses barometer
and GPS module, so the height and position are more accurate.
OSD video overlay system has the following features: VTx Voltage, Eng Voltage,
Flight Time, Flight Speed, Flight Height (altitude), Home Direction, Home
Distance, Total Voyage (duration), Lifting Speed (vertical), Longtitude Latitude
(GPS), Satellite Number (Count), Azimuth (location of the plane in the sky from
the perspective of the base station). HOME OK is set when 6 satellites count are
OSD video overlay system button functions
1: Short button press to save the home position, long press to enter
the setup menu. Double-click twice as fast switching video formats (can also be
switched in the Settings menu)
2: Press the Setup menu for the selection function.
Battery voltage calibration:
3: multimeter measures the battery voltage, battery voltage. Calibration voltage
only with 3S calibration.

First Impressions: Initial test. Barometer Altitude 2m+- Distance from
Home 1m+- which is fine . Voyage (Mileage) it seems to add up the gps drift;
unless you need to know your mileage besides duration or voltage, i will turn
this off. 6+ satellites within 15 seconds here. Home direction on two 300m
flights were accurate.. just keep moving, as it uses the gps to determine
directions, and it takes you home. This light Tarot osd was designed for
250 size quad in mind, but i am slapping it onto any fpv models for a quick home
direction and a way to recover a lost model by recording the gps positions.
Dual voltage detection range: 0 ~ 16.8V / 0 ~ 30V
Video output: NTSC or PAL (OSD can be set)
Operating voltage: 7 ~ 16.8V
Current: 100 mA (12V)
OSD module: 46 × 26 × 8 毫米
Weight: 18 g (with GPS module)
Cover the pressure sensor (barometer) with a black sponge to improve altitude readings.
Missions Recaps: During a search mission, point of
interests (POI) are logged, GPS co-ordinates will be
communicated to the ground search crew as well as to the multi-rotors team.
Multi-rotors are sent out for a closer look at the POI. We record the GPS
as a means to recover a model aircraft too.
