BMI160 Latest Stance Accelerometer Gyroscope module 6 Dof inertial Measurement Sensors

Description: Note The item is Enhanced version. Enhanced version: for starting current below 80A, power 135W below the drill.(Not balanced function) 3S 12.6V 40A lithium battery protection board Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery) Product Size: 42 * 55 * 3.4mm (Standard Version / Enhanced Version), 42 * 60 * 3.4mm (Balanced version) Product weight: 8.8g (standard / enhanced version), 9.8g (balanced version) Charging voltage: 12.6V - 13.6V Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use) Continuous charge current (upper limit): 20A Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!). Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit. Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. Note 4: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery. For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery 1 Poor battery use effect = 3 poor battery use effect).

MQ-7 module Carbon monoxide gas sensor detection alarm MQ7 sensor module

he lsm6ds3 is an accelerometer and a huge 8kb FIFO buffer and an embedded processing interrupt function for the gyro sensor, specifically for the mobile phone market. Due to the ability and we have just created this small breakthrough board lsm6ds3 low cost! Each lsm6ds3 breakthrough design becomes super flexible and configurable specifically for many applications. With lsm6ds3 breakout, you will be able to detect the impact, tilt, movement, faucet, step, and even read the temperature! lsm6ds3 can read 6.7ks / s gyro accelerometer data and data on 1.7ks / s more accurate motion detection. As mentioned above, the break also has a buffering capability of up to 8KB between the data read, the host of the other sensors, the drive interrupt pin thanks to the lsm6ds3 built-in FIFO. Each pin has been broken in the lsm6ds3, side of the board, power and I2C functions while the other side of the motion pin controls the SPI function and interrupt the output. Keep in mind that lsm6ds3 is a 3.3V device that provides a voltage greater than ~ 3.6v to permanently damage the IC. Any 5V operating platform requires a logic level shifter.

If you are using the speed control (dimming) to do the product, the shop can provide free
Custom service, can be in accordance with the requirements of the customer to modify the shape of the circuit board, installation
Mode, current and voltage parameters, add other functions, etc
Note that the governor is mainly used in motor speed control, if you are used to LED dimming, must ensure that the LED can also work in direct power supply, the dimming range of the speed governor is from LED to LED directly connected to the power supply is completely extinguished between dimming, if LED is directly connected with a power that will burn through dimmer the dimming is burned, which typically requires a series current limiting resistor, if you don't know how much resistance can contact customer service.
