Product overview
The Kimpok KP-T1245 is a wireless video transmitter module for FPV drone flight, racing and aerial photography. Its architecture combines FM transmission with PLL frequency control, a built-in aluminum heat sink and a fan for active cooling. The approximately 38.8 g module occupies 48.5 × 35 × 21.5 mm, giving integrators a defined component envelope for installation. Its 16 channels are arranged across two eight-channel groups within 1080–1360 MHz, with selectable output settings from PIT through 4.5 W.
Integration connections comprise DC power input, two grounds, a 5V output, CVBS video input, an IRC control input and an SMA antenna port. IRC supports channel and power adjustment, including OSD parameter adjustment. Power input must remain within DC 7–30V with correct polarity, and the RF antenna must be fitted correctly before power-on to avoid damage. Temperature protection accompanies the active cooling, while the operating range is -10°C to +60°C. The transmitter surface can become hot during use and should not be touched directly.
