Grove - Buzzer is a simple yet enjoyable twig to use. It can output noise at a volume over 85 dB and is integrated with Grove interface, which makes it easy to connect and experiment by just plug & play. It is a perfect add-on for all kinds of Arduino projects and human-machine interfaces.

This module is based on 2-Coil Latching Relay

Volume Adjustable Grove Interface

Grove - Recorder v2.0 is an upgraded recorder with enriched features and is able to record 8-20 seconds of audio with high-quality and natural voice.

The Grove RS-485 allows your Arduino connect with RS-485 device easily, you just need to plug and play. RS485 is cost-effective solution in serial communication, it can be used to data rate at 10Mbit/s or distance up to 1200m at lower speed.

Grove Relay can handle the current up to 5A at 250VAC for long periods of time. When the relay is switched on, the LED will light up and the relay will allow current to flow. The peak voltage capability is 250V at 10A.

The Grove ? RS232 is made for an easy microcontroller connection with your computer. It allows simple Arduino serial communication to take place, through plug and play instead of having to solder, use jumper wires, etc.

Grove - DS1307 RTC is based on the clock chip DS1307 and supports I2C communication! It uses a Lithium cell battery (CR1225). We choose to use the RTC based on DS1307 as it is low cost and also very energy efficient. It can run for years on a very small coin cell. 

The Grove - MP3 is a 20x40mm super mini Music module based on WT2003S-20SS audio decoder.

The Grove Speaker Plus includes a powerful amplifier driver board and a fancy speaker. With the help of the on-board potentiometer, you can easily adjust the output volume. You could replace the speaker with other speakers you like as it adopts separated and replaceable speaker design. 

Grove Passive Buzzer is a low cost tunable passive buzzer.

Grove - I2C Motor Driver(L298P) is a common-use motor driver for stepping motor and servo motor. It embeds an STM32 chip for burning the code to control the motor driver.

Grove - Serial Camera Kit includes one control board and two interchangeble lenses, one is standard lens and the other is wide-angle lens

Grove - I2C Motor Driver (TB6612FNG), DC motor, stepper motor

Grove ? 16-Channel PWM Driver (PCA9685) is a 12-bit PWM driver based on the NXP PCA9685 and can drive up to 16 servos with an external power supply of 5V. 

Grove - Solid State Relay, SSR, switch

The Servo motor is a rotary actuator that allows for precise control of angular position which makes them suitable for use in closed-loop systems where precise position control is needed and is commonly used in electronics. Grove - Servo is a bonus product for Grove lovers as we regulated the three-wire servo into a Grove standard connecter. You can plug and play it as a typical Grove module now, without jumper wires clutter. 

The Grove ? Mini I2C motor driver is a very tiny motor driver with I2C interface, and it includes two motor driver chips - DRV8830, which helps you control two DC motors or winding of stepper motors on a small board simultaneously

Grove - Water Atomization is a perfect module for you to quickly DIY a humidifier with Arduino. You can also develop more advanced and interesting projects with digital scent technology and any other situations in which atomization required.

An electromagnet is a type of magnet in which the magnetic field is produced by electric current
