Grove Base Hat for Raspberry-Pi

Add Grove connectivity on your Raspberry-Pi

This Grove HAT for Raspberry Pi is an expansion board designed by Seeed Studio. This hat will allow you to connect Grove sensors and actuator in order to develop solution with your Raserry-Pi.

It use GPIO PIN wired to various functions (GPIO replicated for other usage) and append additional Grove ports based on the onboard microcontroler chip (MM32). The microcontroler offers additional interfaces as Analog reading.

The hat features:

• Grove & GPIO Pi Hat for Raspberry Pi Series: Break out all the GPIO pins and power of the Raspberry Pi to provide 15 multi-function Grove ports. Also break out the 12-bit ADC pins of MM32 microcontroler chip
• Rich Peripherals for Grove: Provide 15 Grove ports including 3× I2C, 1× UART, 6× Digital, and 4× Analog, which also contains 1x PWM port, and the SWD Debug interface.
• Plug and Play: that's Grove connector. Plug your existing grove module and play with Benefit from convenient Grove connectors that supports more than 60 Grove modules

The Grove Pi Hat is compatible with Raspberry Pi 2 / 3B / 3B+ / 4 / 5 / Zero. It will be your good assistant when you try to start your projects with Raspberry Pi.
