Back-connection protection of power supply(Protect control panel only,Reverse power supply does not protect steering gear). Angular pulse width adjustable. Wired,Wireless (Can be used as a cable board,Launch plate,Receiver board usage). With out-of-control protection(When the signal of the mitter board is not received,Automatically align the steering gear). Accuracy:10position(That is to say, the output signal is divided into two parts.1024A few points,Common servo controller output only256A few points,that is8Bit accuracy). Power supply voltage: 5-7.4V (the board itself can withstand 5-24V voltage, but since the power supply is directly to the servo, and the power supply voltage of the general servo is 5-7.4V, the user only needs to supply power according to the power supply voltage of the servo). Power supply current: 1A for one servo (the servo controller itself only needs about 30MA for power supply, but since the power supply also directly drives the servo, the power supply current must 1A for one servo, the larger the current, the better). Output signal: frequency 50HZ, period 20MS, pulse width can be adjusted, maximum 0.5-2.5MS, minimum 1.5MS, that is, the servo can be controlled to rotate from 0 degrees to 180 degrees or 270 degrees. Colour:red Material:plastic Due to different batches, there may be differences in product appearance and printed text, which not affect use Package Contents: 1 x Wireless Servo Controller 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.
