The Raspberry Pi 4 Model B requires a stable 5V DC power source with at least 3A current to operate reliably, especially when using USB peripherals, HDMI displays, or connected HATs.
The Raspberry Pi 4 Model B (4GB) requires a 5V/3A power supply. Users can use official or certified adapters, such as:
| Model | Recommended (voltage/current) | Raspberry Pi power supply |
|---|---|---|
| Raspberry Pi 4 Computer Model B 4GB | 5V/3A | Raspberry Pi 4 Power Adapter 5V 3A |
| 5V/3A | Raspberry Pi 25W Power Supply Adapter Type C CE Certified | |
| 5V/3A | Raspberry Pi Official 27W Power Supply Brand WaveShare |
We recommend using an SD card with at least 32 GB of storage for Raspberry Pi OS installations. For Raspberry Pi OS Lite, we recommend at least 16 GB. You can use any SD card with a capacity of less than 2 TB. Capacities above 2 TB are currently not supported due to limitations in the MBR. As with any other boot media, you’ll see improved performance on SD cards with faster read and write speeds.
If you’re unsure which SD card to buy, consider MicroSD Memory Card 64GB Class10 with Raspberry Pi OS.
The Raspberry Pi 4 General Purpose Input Output (GPIO) header has 40 pins that can be used to send data in and out of the RPi4B along with a few power pins.
The GPIO header consists of the following options:
The Raspberry Pi 4 does not have any analog input pins because it does not include a built-in ADC (Analog-to-Digital Converter). However, you can use an external ADC module that communicates through I2C or SPI to read analog sensors.
All GPIO digital pins operate at 3.3V, so when connecting 5V devices, a voltage level shifter is required. Connecting a GPIO pin directly to a voltage higher than 3.3V can permanently damage the Raspberry Pi’s GPIO circuitry.
The Raspberry Pi uses two main pin numbering systems:
You can choose either system, but it must be specified at the start of your program. For example:
GPIO.setmode(GPIO.BOARD) uses physical pin numbering,
GPIO.setmode(GPIO.BCM) uses BCM GPIO numbering.
Enhance your Raspberry Pi 4 experience with these essential accessories. From storage and power to cooling and protection, these components help you get the most out of your Raspberry Pi 4.
