Introduction of aircraft model motor tester electric regulator(1) Output: ≤ 15mA (5.0)(2) Input: DC 4.2-6.0v(3) Output signal: 1.5ms soil 0.5ms(4) Size: 46*32* 17mm(5) Weight: 8g(6) Adjustment mode: manual, automatic, middle positionFeatures: it can easily detect and set the virtual position, jitter and middle position of the server, and can connect two groups of steering gear or electric regulator; Single chip microcomputer control, good stability and high precision. Rotate the knob to detect the steering gear.If you connect the electronic governor (brush or brushless), you can get rid of the remote control equipment for manual speed regulation. It is very practical to test the performance of the governor or motor, and there is no need to connect the remote controller and receiver.It is equivalent to a "manual receiver" function, which simulates the steering of the transmitter through the knob

Aircraft model motor tester - Characteristics of electric regulatorReferring to the following picture, the left side is connected to the steering gear, which is divided into three groups: upper, middle and lower, and can be connected to three steering gears; The single row pin on the right is connected to the power supply, and the negative pole (see the identification symbol) near the side is connected to the negative pole of the battery,Be sure not to connect it reversely. If the power supply is connected reversely, the pin corresponding to the IC identifier will be burned, so don't worry. Turn on the power, the blue light will be on at the same time, and then only the first one on the left will be on,For manual adjustment potentiometer test, press the key, the middle light is on, which is the centering test: the third light is on, and the automatic test. The connection method of testing the electric regulator is the same as that of the steering gear,But don't connect the power supply at the input end. The test motor needs to be connected to the electric regulator first, which is the same as the test electric regulator!Basically mark the upper pin, control and indicator of the steering gear tester. The pin corresponding to the s flag is of little use here and can be ignored. The steering gear connected to the left can be divided into three groups: upper, lower and middle, which can test three steering gears at the same timeConnect the power supply from the single row pin on the right, the three blue lights will light up at the same time, and then the light onthe left will light up. At this time, you can select the three modes through the mode selection buttonWhen the light on the left is on, it is in the manual adjustment mode. You can directly use the potentiometer (and the adjustment knob) to control the rotation of the steering gear, and then press the button. The middle light will be on. At this time, it is the centering test. Pressthe button again The light on the right will be on, which is for automatic test. The steering gear will rotate continuously, and then rotate in the opposite direction after it is stuck. One cycle. The connection method of testing the electric regulator is the same as that of the steering gear. When testing the motor, you need to connect the electric regulator first. The method is all according to the above steps

Product description of DC stepping motor actuator drive board moduleThe original adafruit motorshield kit is one of our favorite kits, which is why we decided to make something better. We have upgraded the shielding kit,A simple way to drive DC and stepper motors. This makes your next robot project work fast! We have been able to drive up to four DC motors or two stepper motors, but many improvements have been added:Instead of i293d Darlington drive, we now have tb6612MOSFETDriver: 1.2A and 3a peak current capability per channel. It also has a low voltage drop across the motor, so you get more torque from your battery and have a built-in flyback diode.We don't use the PWM pin of lock and Arduino. We have a completely dedicated PWM driverOn chip. This chip handles all motors and speed control12C。 Only two pins (SDA and SCL) are required to drive multiple motors, becauseAs it is I2C, you can also connect any other 12C device or shieldTo the same pin. This also makes it compatible with any Arduino and completelyStacking design: 5 address selection pins means up to 32 stackableStack this is 64 step motors or 128 DC motors! Many other minor changesFor example, the polarity protection FET on the power pin and some prototype areas oThe shield is assembled and tested here, so all you have to do isSolder on straight or stacked head and terminal blocks. Let's take a look at these specifications: 2 hobby servo connected to 5V, high-resolution dedicated timer connected to Arduino_ No jitter!4h - bridge: tb6612 chipset provides thermal shutdown protection and internal return protection diode for each bridge (3a peak). It can be at 4.5vdc Run the motor to 13.5vdc Up to 4 bidirectional DCMotor with 8-bit speed selection (therefore, about 0.5% resolution)Up to 2 stepper motors (single pole or double pole) with single coil, double coil, crossover or micro step. The power supply of electricvehicles is automatically disabled, and the large junction box connector is easy to connect wires(18-26awg) and power supply Arduino reset button bring top polarity protection 2-pin terminal block and jumper to connect external power supply for independent logic / motor power supply test compatibilityArduino uno, Leonardo, rightful / megar3, expired, reduplicated Mira and duemi lanove. Use mega/ should 2, and use 2 jumpers earlier. download Easy to use Arduino software library, with a shield for assembly and testing, terminal block, common head, jumper. Some welding is required to assemble the head. Stack heads not included
