Description: Grove - Base Hat for Raspberry Pi - Overlay for Raspberry Pi 4B/3B+/3B.
Overlay forRaspberry Pi 4B / 3B+ / 3BbasedSTM32microcontroller with 12-bit ADC, with Grove connectors, allows the connection of sensors and modulesfrom the Grove seriescommunicating througha digital, analog, I2C, PWM, UART interface. Currently more than 60 Grove modules are supported by the Grove Base Hat.
Due to global problems with availability of STM32F030F4P6TR chip, the manufacturer of the overlay replaced it with MM32F031F6P6 chip. The basic functionality of the overlay has not changed.
The item on sale is the Grove Base Hat, Raspberry Pi mini computer can be purchased separately.
|
Attention! The overlay operates at 3.3 V, do not connect higher voltage, as this may result in permanent damage to the board. |
The module for communication with the Raspberry Pi mini computer uses an I2C interface with the address 0x04. Base Hat operates at 3.3 volts.
Grove Base Hat overlay insertion for Raspberry Pi
The cover plate is equipped with 15, 4-pin Grove connectors with digital, analog, PWM, I2C, UART and GPIO interfaces. Additionally the board has all GPIO Raspberry Pi connectors.
