SEENGREAT GPIO Expander for Raspberry Pi Pico Expansion Boards Dual GPIO Expansion Plus S1 2 x 20 Pin Pico with Micro SD Card Slot 3.5 mm Audio Jack Reset Button

Produktbeschreibung

This GPIO Expander Plus S1 for Raspberry Pi Pico is equipped with all Pico LED status indicators leading to GPIO, adding one Full-color RGB, cool LED can be seen when running the demo code; one card slot for Micro SD card; a buzzer with switch, open when using, close when not using. A 2.54mm 4PIN header is reserved to lead out the power supply pin, data pin, and two ground pins. It can be used with multiple expansion modules, such as DS18B20 temperature sensor, DHT11 temperature and humidity sensor and so on. An ESP-01 transfer module solder joint is reserved to support IIC bus and UART. There is also a standard 3.5mm audio jack, which supports dual channel and left channel switching. A reset button. This product increases the reset button, so it is convenient for users to debug or write programs without frequent plugging USB line of Pico. Easy for users to reset the program. Two sets of 2*20 external expansion pins. It is easy of Two sets of 2*20 pins to access to the raspberry PI Pico expansion board or dupont wire to peripherals. Both sides of the board are marked with clear pin function silk screen, which is convenient foruse and measurement. The 4 HY-2.0-4P connectors can be inserted into 2.0mm-spaced cables. A group of pin headers leads to the SPI1 interface, which can be connected to the SPI peripheral module through flat cables or DuPont cables. 5V power supply voltage (provided by PICO). We will provide Python open source demo codes that can be used for Raspberry Pi Pico development board.
