UltraMicro FPV Camera Operation manual/specification REV A
Overview:
The UltraMicro FPV camera is a micro VGA imager paired with digital to analog converter and micro transmitter
for use with ultralight RC airframes. Its 1S (3.5-4.5) volt input is designed to share onboard power supply with the
micro craft (commonly powered off 1S lipo packs). The camera has DC-DC step up regulator to ensure proper
operation even if supply voltage drops due to air frame demand. Low power transmitter allows for FCC license
free use and is suitable for indoor and short range performance.

Operation
When power is applied (3.3 – 5.5V) the camera and transmitter are powered. The camera has memory so the
transmitter will power up in the last used channel. The top LED shows the camera has power and the lower LED
flashes when channel is changed (by depressing button). The channels scroll sequentially from ch 1-7 (and back
to 1). Only on channel 1 is the channel indicator a solid light.

Detailed Operation
Image is focused onto the 1/6” digital imager via the 0.95m lens. The lens has an IR filter to condition the light
entering the imager to optimize image color. The camera board has an A/D conversion circuit that converts the
VGA digital imager signal into an NTSC analog signal. The analog signal is transferred to the transmitter PCB
and the RF circuit encodes the modulated analog signal onto the 5.8 Ghz carrier signal. The 5.8Ghz carrier
signal is sent up the 50 ohm impedance antenna line to the antenna. The antenna is tuned to resonate at 5.8Ghz
and the signal is transmitted into open space to be received by a compatible receiver.
