— | The block for testing servo drives is designed to test the performance of the servo drive and determine its extreme angles. Allows you to estimate the speed of movement and the minimum step. It can be very useful for RC modellers as it allows you to quickly get the drive up and running and test the model before the control electronics are ready. Up to 3 servos can be connected to the servo tester at the same time, such as SG90, SG92R, MG90S, MG995, MG996, EMAX ES08MA, etc. It has three modes of operation: manual, neutral and automatic. In manual mode, the servo position is set by turning the variable resistor knob on the front panel. Neutral mode sets the servo to the middle position. In automatic mode, the servo constantly moves from one extreme position to another. Modes are selected by the "Select" button located in the lower left corner. The current mode is indicated by the corresponding LED above the control knob. Specifications: Output current: ≤ 15mA @5.0V Input voltage: 4.8 - 6 Volts Overall dimensions: 42 x 24 x 23 mm. | 13 | — | — | 50pcs | — | — | — | — | — | — | — | — | — | — | — | |||||||||||||

— | This module is a USB/RS-485 converter, which is designed to interface devices with a PC (personal computer) via an industrial RS-485 interface. The converter can be used to control motors, build a ventilation /air conditioning system, security systems, control the movement of objects, as well as automate production and production processes. The USB to RS-485 interface converter is designed for a distance of up to 1.2 km. External devices can be connected using a conventional twisted pair cable. The converter board is designed based on CH340 and MAX485 chips, 12MHz crystal and other auxiliary components, which ensure the correct operation of the device. The CH340 chip is used to create a virtual COM port when the converter is connected to a PC, and the MAX485 chip ensures the correct connection of an external device. Thanks to the chip, the converter has a sufficiently high data transfer rate via the USB interface and two-way communication. Transmits data over serial output at up to 6 Mbps. The maximum number of devices that can be connected in parallel without additional amplifiers is 32. The converter is connected to a personal computer using a USB port, and to an external device using a screw terminal block. For further work with the converter it is necessary to install the driver. If, when connected, the PC could not install the driver for the converter, then you need to download it and then install it yourself. The converter is powered from the USB port. The converter supply voltage is 5 V. Converter Specifications: Chip CH340 Supply voltage, V 5 USB 2.0 support Maximum data transfer rate, Mbps 6 Maximum data transmission distance, km 1.2 Module dimensions, mm 60 x 17x 8. | — | — | — | 20pcs | — | — | — | — | — | — | — | — | — | — | — | |||||||||||||

— | Converter USB - UART CH340 is used to connect the microcontroller to a personal computer. The module is connected to the computer using the USB interface, and to the microcontroller device via the UART interface with TTL level signals. Often the module is used to connect Arduino boards or other microprocessor devices to a computer. The converter is designed based on the integrated circuit CH340. The chip provides two-way communication and high speed transfer via USB interface, it also emulates a serial output with a speed from 75 bits to 2 Mbits. The main feature of the microcircuit, which distinguishes it from analogues, is its low price. There are 6 pins on the module board. The VCC and GND pins are used as board power, the TxD pin is the transmit line, and the RxD pin is the receive line of the UART signal. If the microcontroller is already connected to its power supply, then the module is connected to it through 3 outputs: GND, TD and RD. The signal level will change on the TxD and RxD lines, which is set by a jumper between the VCC outputs (3.3V, 5V). Please note that the receiver of the RxD module must be connected to the transmitter of the TX controller, similarly, the TxD output of the converter to the RX of the microcontroller. There are 3 LED indicators on the module, where: one LED informs about the voltage supply to the board, the other two indicators signal the activity of the RxD and TxD outputs. If, when connecting the USB-UART CH340 converter to the PC, the drivers were not installed automatically, then you need to download them from link and then install them manually. The converter supports all versions of the Windows operating system. In addition, on the manufacturer's website you can download drivers for Linux, MAC OS and ANDROID with application examples. | 5.7 | — | — | 20pcs | — | — | — | — | — | — | — | — | — | — | — | ||||||||||||

— | Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, resistors and capacitors, determines the polarity and types of pins. Test time 1-2 seconds (except for large capacitors). One control button. Automatic shutdown. Specifications: LCD screen 128*64 dots Firmware on the ATmega328 chip - 2.07w Resistance: 0.1Ω - 50MΩ Capacitance: 25pF - 100000uF Inductance: 0.01mH-20H Supply voltage: Krona 9V (6F22) Standby current: 0.02uA Working current: 25mA Calibration: Like any other measuring instrument, the LCR-T4 requires periodic calibration. The developers have greatly simplified this procedure and you do not need special expensive equipment for this. Before starting calibration, prepare a three-pin jumper with a pitch of 2.54 mm and a good quality non-electrolytic capacitor with a capacity greater than 0.1 microfarads. Metal film capacitors of 0.15, 0.22, 0.33 uF are perfect. Install a jumper in the test socket in contacts 1-2-3 and press the button. The tester, having determined the jumper, will begin self-calibration. The progress of the calibration will be shown on the display. About halfway through the process, the procedure will stop and you will be prompted to remove the jumper. Remove it and calibration will automatically resume. After a short time, the tester will offer to install a capacitor in 1-3 contacts. Insert the capacitor and fix it. A few more seconds and the calibration will be over. The result will be a display of the parameters of the installed capacitor. | 45 | — | — | 1 PC. | — | — | — | — | — | — | — | — | — | — | — | |||||||||||||

— | Mica for microwave ovens, dimensions 150x150 mm and thickness 0.4 mm, maximum temperature 500°C. It is widely used to make the protective plate of the wave channel (magnetron channel) in household microwave ovens. It is recommended to replace the protective mica plate at least once a year, depending on the intensity of use of the oven. Fat falling on the mica surface absorbs microwave radiation, which leads to a sharp decrease in useful power at the initial stage, and subsequently the mica itself, the magnetron cap burns out and, finally, the magnetron fails. | 19 | — | — | 100 pieces. | — | — | — | — | — | — | — | — | — | — | — | |||||||||||||
