Product overview
The Kimpok KP-R3300-A is an analog video receiver module for UAV and FPV racing video links. Its 16 channels cover a receive-frequency range of 3170–3470MHz, with 3330MHz as the default. The integration interface provides power input, ground and a video output specified at 1Vp-p, alongside unused and reserved pins. Separate Band A and Band B keys provide frequency switching, with green and blue frequency indicators respectively; a WORK light indicates system operation. The antenna port has a specified impedance of 50Ω.
Electrical integration requires attention to two different supply specifications: the general power listing is 7–36V DC, 2–8S, while the receiver parameter table specifies 4.2–6V operation and the input pin is identified as 5V, accepting 4.2–6V. Operating current is 0.45A at 5V. Receive sensitivity is -95dBm with a CW signal from an E5071C source, and maximum input power is 0dBm. The reserved 6.5M and 6.0M functions are not enabled. Operating limits are -30 to 85°C and 10–95% humidity; storage temperature spans -40 to 90°C.
