This is an updated version of the Grove – I2C Color Sensor module. The new version is based on the color sensor TCS34725FN with digital output I2C.  Based on the 3*4 array of filtered photodiodes and 16-bits analog-to-digital converters, you can gain the color chromaticity of ambient light or the color of objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters and 4 have no filter(clear). With the synchronization input pin, external pulsed light source can provides precise synchronous conversion control

There are 6 Grove connectors in this hub, one input, five output, or you can even connect one hub with another, so that more devices can be plugged in. Not only I2C but also can be used to control several synchronous change devices(like LEDs).

This Motor Driver uses the normal Motor driver chip – L298. In order to use the Grove interface to let the MCU like Arduino or Seeeduino control the Motor Driver, the I2C Grove interface is designed. Besides, there is also an ATmega8L chip on board to enable the I2C connection. As a matter of fact, this motor driver is perfectly compatible with Arduino.

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. This is a 2-channel motor driver, each channel can support up to 1A current. You can also use the I2C interface to transmit data from the peripheral microcontroller. The default I2C address is 0x0f and you are able to change the address of the Motor driver by connecting the I2C wire hat. The I2C address is selectable from 0x00 to 0x0f.

Infrared Receiver (IR) v1.2 especially for you. Infrared is a quick, cheap, and easy method to transmit data. You can transmit infrared signals through an infrared LED, while there is an infrared receiver to get the signals on the other side. You can receive infrared signals via an IR detector on the Infrared Receiver; moreover, you can use it for remote control detection. The IR detector has a demodulator inside it that searches for modulated IR at 38 KHz. The Infrared Receiver can receive signals well within 10 meters. If more than 10 meters, the receiver may not get the signals. We often use the two Groves, Grove – Infrared Receiver and the Grove – Infrared Emitter to work together.
