Green expansion board with 15 Grove connectors and 24-pin GPIO header

Seeed Studio

Seeed Studio Grove Base Hat for Raspberry Pi

SKU CH-HSD6-XMGSQ

Expansion board breaks out Raspberry Pi pins into 15 Grove ports and a 24-pin GPIO header for sensor projects

  • Product typeSensors
  • 15 Grove ports simplify sensor wiring
  • 24-pin GPIO header preserved for direct access
  • 12-bit ADC enables four analog inputs
  • SWD debug interface aids firmware development
  • Compatible with over 60 Grove modules

Expansion Board for Raspberry Pi

The Grove Base Hat adds fifteen Grove connectors to any Raspberry Pi 2, 3B, 3B+ or 4 board while keeping the original 24-pin GPIO header accessible. An onboard MM32F031F6P6 microcontroller provides a 12-bit ADC for the four analog ports. The board exposes three I2C, one UART, six digital and one PWM channel through keyed Grove sockets. It also breaks out an SWD debug interface for firmware work.

Makers who want plug-and-play sensor integration

Developers who prefer solderless wiring and instant compatibility with over sixty Grove modules will find this board a natural fit. Builders who need bare-pin access only or who are using a non-compatible single-board computer should look elsewhere. The hat is not suited for projects that require high-current drivers or isolated industrial interfaces.

15 Grove ports on a 24-pin GPIO pass-through

The single specification that decides fit is the combination of fifteen multi-function Grove sockets plus an untouched 24-pin Raspberry Pi header on one board. If your design needs both the full Grove ecosystem and simultaneous access to every standard GPIO pin, this hat matches that requirement exactly.

Questions about this item

What comes in the box and what must I buy separately?

The board itself is supplied; Raspberry Pi and any Grove sensor modules are sold separately.

Which version should I choose for my Raspberry Pi model?

This single version fits Raspberry Pi 2, 3B, 3B+, 4 and Zero boards.

What does the 12-bit ADC mean when I read an analog sensor?

The MM32 chip gives 12-bit resolution on the 4 analog Grove ports for finer sensor readings.
