<p>Overview:</p> <p>This four-in-one tuner module integrates four RF chips, CC2500, NRF24L01, A7105, and CYRF6936, into one circuit board. It can identify the PPM signal output by a remote control, and then convert it into the corresponding remote control protocol to control the receiver or the aircraft. Currently, it supports protocols for , HorizonHobby DSM2, , , , Weili, , HISKY, and Futaba SFHSS Assan.</p> <p>The module can more flexibly and conveniently control four different of quad-copters, helicopters and fixed-wing aircraft. Since you continue to use the familiar remote control, the operation feel and flight experience are also better.</p> <p>color: Black</p> <p>material: plastic</p> <p>Note:</p> <p>The STM32 MCU have change to ARM, firmware is ARM -M</p> <p>Attention:</p> <p>We only TX module hardware. Its software is based on open source firmware, which is burned by us, and users should bear the risk of using it.</p> <p>Working Parameters:</p> <p>Working voltage: 5-9V</p> <p>Working current: 150mA</p> <p>Working frequency: 2.4G ISM band</p> <p>RF power: +22dBm</p> <p>Main control chip: ARM -M(128K ROM, 20K RAM)</p> <p>Package Contents:</p> <p>1 x IRX4 Lite 4-In-1 Module</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
