Grove Raspberry Pi Hat

The Grove Base Hat for Raspberry Pi provide Digital/Analog/I2C/PWM/UART port to meet all your needs. With the help of the build-in MCU, a 12-bit 8 channel ADC is also available for Raspberry Pi.

Currently, more than 60 groves have supported the Grove Base Hat for Raspberry Pi. In addition, Seeed Studio will continue to add new compatible modules to the compatible list, the more you use, the more grove will be added.

Compared with Grove Pi+, the Grove Base Hat for Raspberry Pi does not use the ATMEGA chip for data conversion, so it runs faster. Seeed Studio provides the Raspberry Pi driver for Grove Base Hat for Raspberry Pi. What's more, Grove Base Hat for Raspberry Pi is much more cost-effective. In other words, we lowered the threshold for using the grove series on the Raspberry Pi.

Note

Because ST32 series chips are out of stock globally, prices have increased several times and there is no clear delivery date. We have no choice but to switch to the MM32 chip. The specific replacement models are as follows: STM32F030F4P6TR is replaced by MM32F031F6P6. After the chip is replaced, the product functions, features, usage methods and codes remain unchanged. It should be noted that the firmware version has changed, and the factory firmware has been adjusted according to different chips. If you need to re-burn the firmware, please download the firmware corresponding to the chip. Moreover, the IIC address of MM32 is 0x08, while the STM32 is 0x04.
