Raspberry Pi Zero 2W is an upgraded version and a much faster version of Raspberry Pi Zero, it can be used as a minicomputer to carry out quite lightweight tasks. Before getting started with the Pi Zero 2W the pin configuration should be known as it will help in making effective use of this single-board computer. So, if you are a newbie and looking forward to getting your hands on Raspberry Pi Zero 2W then read this as it will explain the pin configuration of Pi Zero 2W.
Specifications of Raspberry Pi 2W
Raspberry Pi foundation claims the Pi 2W is five times faster than its predecessor as it comes with 64-bit quad-core processor having a speed of 1 GHz and an SDRAM of 512 MB. To further dig deeper into its specifications there is a table below that states the specifications of Raspberry Pi Zero 2W.
| Specifications | Raspberry Pi Zero 2W |

| RAM | 512 MB |
| Connectivity | Bluetooth 4.2, 2.4GHz Wireless/LAN |
| Graphics | Open GL 1.1 and 2.0 Graphics |
| Ports | 1xMicro USB On-The-Go (OTG) port, 1xMini HDMI port, 1xCSI-2 camera port, 1x Micro USB power port and Micro SD card slot |
| GPIOs | 40 HAT compatible header pins |
Raspberry Pi Zero 2W Pinout
From the specifications stated above you have gotten an idea of what this board is capable of so now jump to the pinout that will help you a lot while using Pi Zero 2W. Before going into the details of the pins of Raspberry Pi Zero 2W there is a table below that summarizes the pins and their description for better understating.
| Pi Zero 2W pins | Representation of Pins | Pin Description |
| General purpose pins | (11-13), (15 -16), (18-19), (21-24), (26), (29), (31-33), (36,37) | These are the pins that can be used for any purpose |
| Power Pins | 1& 17 for 3.3 volts, 2 & 4 for 5 volts
(6), (14), (20), (25), (34) and (39) as GND |
To supply power to the devices connected to Pi |
| Communication pins * | (3), (5), (27), (28) for I2C
(7-11) for SPI0 (16-21) for SPI1 (8 & 10) for UART |
Pins that can be used for I2C, SPI, and UART communication |
| Pulse code modulation (PCM) Pins * | 12,35,38,40 | These pins are used to represent the analog signals in digital form |
*The order while using the communication pins should be kept in mind which is: SDA, SCL, TX, RX, SPI0 MOSI, SPI0 MISO, SPI0 SCLK, PCM DIN, and PCM DOUT.
FAQs
Q: Do All Raspberry Pi Boards Have the Same GPIOs?
Yes, all Raspberry Pi single board computers have the same set of GPIOs, but it is always instructed to see the device user manual before using it.
Q: What Is BCM Mode in Raspberry Pi?
This mode makes the GPIOs non sequential and is called Broadcom mode, it is named after the company that makes the CPU of Raspberry Pi.
Q: Does the Raspberry Pi zero 2W have Wifi?
No, Raspberry Pi 2W does not come with wifi as it is a board with the lowest form factor, but if you need wifi then you add this feature bay plugging in the wifi dongle.
Q: Does Raspberry Pi 2 W need a fan?
No, Raspberry Pi 2W does not require a fan for cooling normally but it might require a fan in case you are running any heavy application on it.
Conclusion
Before getting started with any board of Raspberry Pi there are two things that one should keep in mind one its specification and other is its pinout. Raspberry Pi Zero 2W like other boards have the 40 GPIOs which are further separated on the basis of their functionality.
