What do you need to know about pinout on Raspberry Pi?

Pinout! The Raspberry Pi GPIO pinout guide. This GPIO Pinout is an interactive reference to the Raspberry Pi GPIO pins, and a guide to the Raspberry Pi’s GPIO interfaces. Pinout also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs. Support If you love Pinout, please help me fund new features and improvements:

Is the lf411 a low offset drift amplifier?

LF411 is a Low offset drift JFET input Operational Amplifier. The device utilizes JFET input operational amplifiers with very low input offset voltage and guaranteed input offset voltage drift. They require a low supply current yet maintain a large gain bandwidth product and fast slew rate.

How are the pins on a Raspberry Pi muxed?

Pin Muxing. Some GPIO pins can perform multiple functions. By default, pins are configured as GPIO inputs. When you open an alternate function by calling I2cDevice.FromIdAsync() or SpiDevice.FromIdAsync() , the pins required by the function are automatically switched (“muxed”) to the correct function.

Where is the GPIO pin on a Raspberry Pi?

Rev 1 Pi – alternate GPIO/BCM numbers for the original, 26-pin model “A” and “B” Pi. What’s the orientation of this pinout? Pinout depicts pin 1 in the top left corner.

What’s the pin number on a Raspberry Pi Zero?

BCM – Broadcom pin number, commonly called “GPIO”, these are the ones you probably want to use with RPi.GPIO and GPIO Zero. WiringPi – Wiring Pi pin number (shown as a tooltip), for Gordon Henderson’s Wiring Pi library.

What are pins 27 and 28 on Raspberry Pi 4?

The pins 27 and 28 are reserved pins. They are usually used for I2C communication with an EEPROM. If you just begin with Raspberry Pi 4 pins, just don’t connect anything to those pins.

Where are the power pins on a Raspberry Pi 4?

Physical/Board pin 2 The 5v power pins are connected directly to the Pi’s power input and will capably provide the full current of your mains adaptor, less that used by the Pi itself. With a decent power supply, such as the official 3A adapter on the Pi 4, you can expect to pull about 1A to 2A.

What’s the max number of pins on a GPIO?

Maximum total of all pins 50 mA. Default 8 mA max per pin. (Returns to this configuration after reset.) Software configurable from 2 mA to 16 mA. Do not source or sink more than what you’ve configured.
