Description: Grove - Base Hat for Raspberry Pi Zero - Overlay for Raspberry Pi Zero.
Overlay forRaspberry Pi Zero / Zero WbasedSTM32microcontroller with 12-bit ADC, with Grove connectors, allows to connect sensors and modulesfrom Grove seriescommunicating throughdigital, analog, I2C, PWM, UART interface. Currently more than 60 Grove modules are supported by the Grove Base Hat.
The module for communication with the Raspberry Pi minicomputer uses an I2C interface with the address 0x04. Base Hat works with a voltage of 3.3 V.
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.
|
Attention! The overlay operates at 3.3 V, do not connect a higher voltage, as this may result in permanent damage to the board. |
Grove Base Hat overlay inputs for Raspberry Pi Zero
The cover plate is equipped with 8, 4-pin Grove connectors with digital, analog, PWM, I2C, UART and GPIO interfaces. Additionally the board has all GPIO Raspberry Pi connectors.
