The Grove Base Kit for Raspberry Pi is one of the best kits for beginners to get started with Raspberry Pi. No troublesome soldering and no complicated wiring. You can focus on learning Raspberry Pi. This kit includes a Grove Base Hat for Raspberry Pi and 10 Grove modules, which covering the sensor, actuator, and display. All you need to do is following the demo, plug the module into the Grove Base Hat, truly plug and play.

On top of that, we have provided you with detailed instructions on the use of Raspberry Pi and the use of each module, which including 8 lessons for the module. Just click the wiki to view the user manual. Also, you can check the video guide below which will tell you how to use this kit step by step.

All in all, whether you are a student, teacher, artist, hardware enthusiast, and so on, with the help of the Grove Base Kit for Raspberry Pi,  you will get to know Raspberry Pi quickly and comprehensively.

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before your use of the product.

Hardware Overview

The images below show an overview of Grove Base HAT hardware features. The pin-out and alternate functions of various pins of Grove Base HAT are shown in the pin-out diagram. This could be used as a quick reference.

 Digital Port: 2 digital Grove ports are used to connect Grove digital sensors.

 Analog Port: 2 analog Grove ports are used to connect Grove analog sensors. Raspberry Pi does not support analog signal. So we use the ADS1015 chip to transfer the ADC signal to I2C signal.

 I2C Port: 3 I2C Grove ports are used to connect Grove I2C sensors.

 UART: 1 UART Grove port is used to connect Grove UART sensors. The UART of Raspberry Pi 3 is used by bluetooth. Please follow THE RASPBERRY PI UARTS to enable the UART.

 System Power Switch: Slide switch is used to change the logic level and operating voltage of the board to either 5V or 3.3V.

 ADS1015: ADS1015 is precision analog-to-digital converters (ADCs) with 12 bits of resolution, Data are transferred via an I2C-compatible serial interface.

 TXS0108: This 8-bit non-inverting translator uses two separate configurable power-supply rails. The A port tracks the VCCA pin supply voltage. The VCCA pin accepts any supply voltage between 1.2 V and 3.6 V. The A ports are conencted to Raspberry. The B port tracks the VCCB pin supply voltage. The VCCB pin accepts any supply voltage between 1.65 V and 5.5 V. The B ports are conencted to Grove sensors.

 FREE: The FREE pins are not used by Grove Base HAT.

Grove Modules

Grove – Buzzer

This module uses piezo buzzer as the main component, it can produce high pitch tone while it is connected to digital output and logic level set to High, otherwise it can produce various tones according to the frequencies generated from the Analog PWM output that connected to it. (note: the frequency range that normal human ear can distinguish is between 20 Hz and 20kHz.)

Grove – Temperature & Humidity Sensor (DHT11)

This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below 0 degree.

Grove – 16 x 2 LCD (White on Blue)

This Grove – 162 LCD module is a 16 Characters 2 Lines LCD display, it uses I2C bus interface to communicate with the development board, thus these will reduce the pin header from 10 to 2 which is very convenient for the Grove system. This LCD display module also supports customise characters, you can create and display heart symbol or stick-man on this LCD module through a simple coding configuration.

Grove – Red LED Button

The Grove – LED Button is composed of Grove – Yellow Button, Grove – Blue LED Button and Grove – Red LED Button. This button is stable and reliable with a 100 000 times long life. With the build-in LED, you can apply it to many interesting projects, it is really useful to use the LED to show the status of the button.

Grove – Light Sensor

The Grove – Light sensor integrates a photo-resistor(light dependent resistor) to detect the intensity of light. The resistance of photo-resistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e. based on resistance value). The output signal is analog value, the brighter the light is, the larger the value.

Grove – mini PIR motion sensor

Grove – mini PIR motion sensorallows you to sense motion, usually human movement in its range. Simply connect it to Grove – Base shield and program it, when anyone moves in its detecting range, the sensor will output HIGH on its SIG pin.

Grove – Moisture Sensor

This Moisture Senor can be used for detecting the moisture of soil or judge if there is water around the sensor, let the plant in your garden able to reach out for human’s help when they are thirsty. This sensor is very easy to use, you can just simply insert in into the soil and read the data. With this sensor, you can make a small project that can let the plant send a message to you like ” I am thirsty now, please feed me some water.”

Grove – Relay

The Grove-Relay module is a digital normally-open switch. Through it, you can control circuit of high voltage with low voltage, say 5V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed.

Grove – Servo

Grove – Servo is DC motor with gearing and feedback system. It is used in driving mechanism of robots. The module is a bonus product for Grove lovers. We regulated the three-wire servo into a Grove standard connector. You can plug and play it as a typical Grove module now, without jumper wires clutter.

Grove – Ultrasonic Ranger

This Grove – Ultrasonic ranger is a non-contact distance measurement module which works at 40KHz. When we provide a pulse trigger signal with more than 10uS through singal pin, the Grove Ultrasonic_Ranger will issue 8 cycles of 40kHz cycle level and detect the echo. The pulse width of the echo signal is proportional to the measured distance. Here is the formula: Distance = echo signal high time * Sound speed (340M/S)/2. Grove_Ultrasonic_Ranger’s trig and echo singal share 1 SIG pin.
