JQ6500 Voice Module MP3 Module MCU Serial Port Control Broadcast one-on-one 5 Way Control Music IC 16Mbit
The JQ6500 is an MP3 chip that provides serial ports. It perfectly integrates hard decoding of MP3 and WMV. At the same time the software supports the TF card driver, support the computer to directly update the spi flash content, support the FAT16, FAT32 file system. Through a simple serial command to complete the specified music, and how to play music and other functions, without cumbersome bottom operation, easy to use, stable and reliable is the biggest feature of this product. In addition, the chip is also a deeply customized product and is designed for low-cost solutions developed for the fixed voice player field.
JSN-SR04T A86 Waterproof Ultrasonic Rangefinder Module
This is a A86 JSN-SR04T waterproof ultrasonic rangefinder module, The use of industrial-grade integrated ultrasonic probe design, which is stable performance. Its usage is as same as HC-SR04, the measurement distance is accurate- about 0.5cm, the furthest distance can be measured is 4.5m, because it is small so easy to carry , Suitable for a variety of wet and harsh measurement environment. In general we will use it in horizontal ranging, obstacle avoidance, automated control, monitoring of objects and its movement, traffic control, security and artificial intelligence, educational research. There is also a similar JSN-B02 module that is more easy to install and waterproofing.
KY-013 Analog Temperature Sensor Module
The KY-013 Analog Temperature Sensor Module is based on the thermistor (resistance increases with the ambient temperature changes) which sense the real-time temperature of the surrounding environment changes. Change in temperature data in analog form can be taken from this module on analog IO pins, then through any microcontroller, it can be easily converted and displayed in Celsius degrees or any other respective Unit.
KY-026 Flame Sensor Module
The Flame Sensor Module can detect flames in the 760-1100 nanometer wavelength range. Small flames like a lighter flame can be detected at roughly 0.8m. The detection angle is roughly 60 degrees and the sensor is particularly sensitive to the flame spectrum.
An on-board LM393 op-amp is used as a comparator to adjust the sensitivity level. The sensor has a digital and analog output and sensitivity can be adjusted via the blue potentiometer.
KY-036 Metal Touch Sensor Module
L298 2A Dual Motor Driver Module with PWM Control
This L298 Based Motor Driver Module is a high power motor driver perfect for driving DC Motors and Stepper Motors. It uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. It can control up to 4 DC motors, or 2 DC motors with directional and speed control

LEM Current Transducer, LA Series, 25A, 0.5 %, Closed Loop Output
The LA 25-NP from LEM is a current transducer. It features instantaneous output, excellent accuracy, very good linearity, low-temperature drift, optimized response time, wide frequency bandwidth, no insertion losses, high immunity to external interference, and current overload capability. This current transducer is used for the electronic measurement of currents (DC, AC, pulsed, mixed) with galvanic separation between the primary circuit and the secondary circuit. It is mainly used in AC variable speed drives and servo motor drives, static converters for DC motor drives, battery-supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), and power supplies for welding applications.
LM317 DC-DC Adjustable Voltage Regulator Power Supply Module
The LM317 DC-DC Adjustable Voltage Regulator Power Supply Module is an adjustable 3-terminal positive voltage regulator. It is capable of delivering more than 1.5 Amp current over an output voltage range of 1.25 to 37 Volts.
The LM317 requires only 2 resistors to set the output voltage. These 2 resistors are available in the form of potentiometers in the module for the convenience of the user. The module also has onboard input and output filter capacitors.
There are 2 set of 2-way connectors for input and output dc voltages.
