1.Supports wide input voltage range, 3V-12V, 5V recommended. 2.Supports PWM, PPM, SBUS, and CRSF signal control. 3.Mainly used to control relays using PWM and other signals. Unlike FET switches, this device establishes a direct physical connection, allowing it to accommodate higher DC voltages and can also connect to AC power or other signals. 4.Automatically identifies input control signals, eliminating the need for manual switching (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: PCB Package Contents: 1 x Motherboard 1 x Pin Header (Angled) 1 x Heat Shrink Tubing Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
