I want present to you my new version of the Bluetooth module for a car, home whatever you want.
This module base on the BK8000L module with an additional power scheme for working with car voltage. But it’s also can work by USB.
You can ask me why need to create something new if you can easily buy already exists solution from China?
Here are some pluses:
1. It works.
2. Noise reduction fr...
Battery power management chip SW3518S (shop number C406811 )
The module can be directly plugged into DC5.5 to use. Charge all kinds of mobile phones with high power and relatively comprehensive agreement.
The input voltage is 12-28V. Do not overpressure.
Dual-port charging solution supporting PD's multi-fast charging protocol
SW3518 is a high-integrated dual-port charging chip with multiple fa...
TPS40057 is a high voltage synchronous buck controller with a wide input voltage range (8V to 52V). TPS40057 has a high degree of design flexibility and can provide a variety of user-programmable functions, including soft start, undervoltage lockout (UVLO), operating frequency, voltage feedforward, high-side current limit, and loop compensation.
This design is to input 12-24V. Design 3A insurance...
The main chip of this module is CS1237.
This chip integrates "amplifier" and "ADC", which amplifies the differential signal of the sensor and turns it into a digital signal.
It is too useful. The module also has power output E+ and E-, which is very suitable for connecting the sensor of the resistance bridge type.
• The module supports differential input, -0.5VCC to +0.5VCC
• Module built-in te...
This EEPROM module takes the M24C02-WMN chip as the core and is used to realize the power-down preservation of data.
The working voltage is compatible with 3.3V and 5V systems, and compatible with 100/400kHz IIC bus communication.
This module leads the address interface A0/A1/A2 of M24C02.
Users can change the bus address of 24C02 by configuring Ax,
and mount up to 8 modules on the bus to achie...
Use the Hall chip OH34N to convert the changed magnetic field signal to a digital level output.
When the S pole magnetic field is triggered, the module will output a low level. As a non-contact switch, it is widely used in various position control, speed detection, flow detection, and product quantity detection on the production line.
Module input voltage 3.5V-5.5V
S pole magnetic field trigge...
this is a simple **dark sensor** project that is connected to a relay which u can connect to a domestic light or fan etc. thedevice make sure that when there is light, the relay will be switched OFF and when it's in the dark, therealy is turned ON.
THIS IS AN SMD LM386 CIRCUIT. IT CAN BE USED LIKE A WALKIE TALKIE BUT WITH A MUCH MORE CLEAR SOUND.CONNECT A ELECTRET CONDENSOR MICTO THE "IN" PIN AND "GND" AND FIX A SPEAKER TO THE OUTPUT END.(IF U WANT, CONNECT A LONG WIRE TO THE MIC OR SPEAKER) AND SPEAK THROUGH THE MIC.ITS A REAL FUN AND CHEAP CIRCUIT TO PLAY WITH.
The module KY-012 Active buzzer module is part of the series "37 In 1 Sensor Module Board Set Kit For Arduino" the module consists only of an active buzzer that has an oscillator inside it so just power the buzzer and it will emit a sound, typically at the 2500Hz frequency. Through this module it is not possible to determine the frequency of the sound, for this function it is necessary the passive...
Simple module for creating your own led lamp. You can use RGB strip, WS2812b, one-color strip or others.
