A miniature telemetry solution for your FPV plane

Conventional OSDs offer a host of features, some of which you don’t need
if you’re just flying FPV around your local field or have a small and light
FPV plane that can’t really carry a full OSD. All you really want in those

cases is for your tracking antenna to point at the plane accurately and
have GPS positional data along with vital statistics such as battery voltage
and current consumption.

The TinyTelemetry does just that. It sends the EzTelemetry data required
for the EzAntennaTracker down one of the audio channels on the
audio/video transmitter. The EzAntennaTracker will then track the plane
and offer battery statistics on its LCD display as well as other telemetry
data such as positional info etc. The new v2.0 EzAntennaTracker will also
offer audible warnings for battery voltage and total current consumption.

Equipped with its optional miniature current sensor the TinyTelemetry will
handle up to 6S pack voltage and 50A of current. However for the lightest
of planes the current sensor can be omitted and the battery will be
monitored for voltage alone.

Hooking the TinyTelemetry up is trivial, all you need is to supply it with 5V
(power from a servo channel will do fine) and route the output to an
audio channel on your audio/video transmitter. It comes supplied with a
cable that plugs right into the ImmersionRC transmitter’s JST connector,
which already supplies a regulated 5V. In that case the TinyTelemetry is
ready for use in a mere few seconds.

Installation

Installing the TinyTelemetry on your FPV plane is straighforward. If you are using a ImmersionRC
audio/video transmitter (any type or frequency) all you need to do is connect the supplied cable to the
transmitter and to the TinyTelemetry. If you also want to monitor voltage and current, please follow the
instructions outlined below.

If you’re using a different brand of audio/video transmitter installation might require you to cut and
splice the TinyTelemetry into your wiring. The simplest means of powering the TinyTelemetry is by using
a spare servo channel and route 5V and GND to the appropriate pins. The audio output pin needs to be
connected to the audio/video transmitter’s audio input, please consult the below picture for your
reference. On ImmersionRC transmitters the right audio channel is used by default for EzTelemetry data.
The left channel can then be used for a microphone or a vario. Unfortunately you cannot use a
microphone or another device that generates an audio signal on the same channel as the TinyTelemetry.

The bottom three pins are labelled ‘battery voltage’, ‘current’ and ‘gnd’. Battery voltage allows

monitoring of the flight pack battery voltage. Route this pin to the positive terminal (+) of the battery
pack. If current sensing isn’t required no other connections need to be made.

If the optional current sensor is to be used its cable has to be connected to the TinyTelemetry with the
right orientation. The bottom three pins (battery voltage, current, gnd) correspond with the pins on the
current sensor (carefully observe printing on the PCBs). Obviously the battery voltage pin will now
automatically be connected to the flight pack.

In order to keep weight down to the minimum the current sensor comes without wires or connectors
installed. It is intended to be soldered into your FPV plane and shrinkwrapped after proper operation
has been verified. Take notice that proper soldering is required to make a good and reliable connection
and that shrinkwarp is required to prevent shortcircuits.
