The motor speed control wiring methods: available potentiometer system speed can also be connected to the MCU control, when the potentiometer control wiring, the potentiometer middle pin is connected to VR speed port, potentiometer connected to both ends of 5V and GND terminal voltage more high speed faster. 2. Motor steering control wiring methods: you can switch control can also be connected to the MCU control, to GND in one direction, then in one direction 5V. 3. Pulse speed signal: high and low output. IC can not understand the information with the customer request. Hall signal inputs for hall: Wiring diagram is shown, one corresponding to the HA, HB,HC and on the motor, 5V power supply connected to the motor hal signals positive, GND power supply negative signal to the motor hall. Note: Due to different motor manufacturers to make the hall of hall line order does not necessarily follow the line on the board to match the sequence, need to be adjusted, please parents who pay attention! If the line sequence wrong, does not boot properly, current, or start other phenomena not open, forced to use the drive plate will burn!!! Motor driver board 12-36V DC power input, VCC positive power supply,GND power supply is negative. Electrical wiring methods: Brushless DC motor for the three lines, corresponding MA/U, MB/V, MC/W Tips: If you use less than 60W, without additional heat sink, be sure to add more than 60W heatsink fins drive efficiency without lowering the temperature is too high will shine into permanent damage! The size of the heat sink may be a bad environment based work(recommended cooling surface area greater than 200 square centimeters)!When installing the heat sink,must pay attention to the back of the module 6 MOS pipe insulation, no insulation, it will be adhered to drive plate permanently damaged! Proposes to add insulation films, both sides of the insulating sheet plus thermal grease! Package Includes: 1 x 12-36V 500W Brushless Motor Controler

MAX30102 Heartbeat Frequency Tester Heart Rate Sensor Module Puls Detection Blo Package weight: 0.01 kg Features: - The MAX30102 is an integrated pulse oximeter and heart rate monitor bio sensor module. It integrates a red LED and an infrared LED, photo detector, optical components, and low-noise electronic circuitry with ambient light suppression. - The MAX30102 features a 1.8V power supply and a separate 5.0V power supply for internal LEDs for heart rate and blood oxygen acquisition in wearable devices, worn on the fingers, earlobe, and wrist. The standard I2C-compatible communication interface can transmit the collected values ￢ﾀﾋ￢ﾀﾋto the Arduino, KL25Z and other micro controllers for heart rate and blood oxygen calculation. - In addition, the chip can also shut down the module through software, the standby current is close to zero, and the power supply is always maintained. Because of its excellent performance, the chip is widely used in the Samsung Galaxy S series mobile phones. - Compared with the previous generation MAX30100, the chip integrates a glass cover to effectively eliminate external and internal light interference, and has the best reliable performance. The Main Parameters: LED peak wavelength: 660nm/880nm LED power supply voltage: 3.3~5V Detection signal type: light reflection signal (PPG) Output signal interface: I2C interface Communication interface voltage: 1.8~3.3V~5V (optional) Board reserved assembly hole size: 0.5 x 8.5mm Pin Description: VIN: main power input terminal 1.8-5V 3-bit pad: Select the pull-up level of the bus, depending on the pin master voltage, select 1.8v or 3_3v (this terminal contains 3.3V and above) SCL: the clock connected to the I2C bus; SDA: data connected to the I2C bus; INT: Interrupt pin of the MAX30102 chip; RD: RED LED ground terminal of MAX30102 chip, generally not connected; IRD: The IR LED ground of the MAX30102 chip is generally not connected; GND: Ground wire. Principle Description: - Light-dissolving method: measuring the pulse and blood oxygen saturation by using human tissue to cause different transmittance when the blood vessel beats; - Light source: a specific wavelength of light-emitting diode selective for oxyhemoglobin (H bO 2) and hemoglobin (Hb) in arterial blood; - The transmittance is converted into an electrical signal: the change in the volume of the arterial pulsation causes a change in the transmittance of the light. At this time, the photoelectric variator receives the reflected light from the human tissue, converts it into an electrical signal, and amplifies and outputs it.
