raspberry pi 1B pinout
In the case of the Raspberry Pi, the GPIO ports work at 3.3 V and around 20 mA.
divided into different categories with specific uses.
Power +: Continuous power supply GND: Ground = Return to earth I2C: Synchronous serial protocol SPI: Other synchronous serial protocol UART: Asynchronous protocol + serial to parallel communication conversion. GPIO: General port which can optionally be transformed into I2C or SPI.
The GPIO ports are numbered 1 to 40, starting from the top left when you hold the Raspberry pi GPIO ports to the right. This is the so-called “Board” numbering mode. Another numbering mode exists, which is based on processor addressing, called “BCM” mode.
