When this pin is set to HIGH, the voltage at the output is 3.3V and when set to LOW, the output voltage is 0V. Note: Do not give voltage more than 3.3V to GPIO pins, or else it will fry the Raspberry Pi zero.Ī GPIO pin set as an output pin sends the voltage signal as high (3.3V) or low (0V). A voltage between 1.8V and 3.3V will be read by the Raspberry Pi as HIGH and if the voltage is lower than 1.8V will be read as LOW. GND pin is from where all voltages are measured and it also completes an electrical circuit.Ī GPIO pin that is set as an input pin, receives the incoming voltage signal sent by the device connected to this pin. GND: Ground is commonly referred to as GND. This pin can use to power up the Raspberry Pi zero, and it can also use to power up other 5v devices.ģ.3V: The 3v pin is there to offer a stable 3.3v supply to power components and to test LEDs. The board consists of two 5V pins, two 3V3 pins, and 9 ground pins (0V), which are unconfigurable.ĥV: The 5v pins directly deliver the 5v supply coming from the mains adaptor. Top 15 Raspberry-pi Zero projects for 2021 Raspberry PI Zero Power Pins: GPIO pins do not have a specific function and can be customized using the software. The standard interface for connecting a single-board computer or microprocessor to other devices is through General-Purpose Input/Output (GPIO) pins. Like every Raspberry Pi chipset, Zero consists of a 40-pin GPIO. One powerful feature of the Raspberry Pi is the row of GPIO (general-purpose input/output) pins along the extreme right edge of the board. **Download HD R-Pi Zero Pinout image from here. Raspberry Pi Zero GPIO Pinout in detail: Raspberry Pi Zero GPIO Pinout It consists of a 1GHz BCM2835 single-core processor, 512 MB RAM, mini-HDMI, USB On-The-Go ports, and a camera connector. And the 40pin GPIO is unpopulated which provides the flexibility to use only the connections that the project requires. The Raspberry Pi Zero supports mini connectors (like mini HDMI, mini USB power, and USB on-the-go port) to save more space. Raspberry pi Zero GPIO Pinout or Pin diagram, and programming methods are explained in detail in this post.

Raspberry Pi Zero is the smallest chipset in the Raspberry Pi series and is 40% faster than the original Raspberry Pi but nearly half of its size. It is developed by the Raspberry Pi Foundation in the United Kingdom along with the association of Broadcom. Raspberry Pi is a mini single-chip computer.
