Raspberry Pi 4 GPIO Pinout has 40 pins: 26 GPIO pins, two 5V pins, two 3V3 pins, and 7 ground pins (0V). GPIO pins of RPI 4 are capable of generating PWM output and the board supports SPI, I2C, and UART serial communication protocols. Introduction to Raspberry Pi 4 The Raspberry Pi 4 Model B … Read more
The Raspberry Pi 1 was one of the first single-chip computer developed in the UK by the Raspberry Pi Foundation. It is a small, efficient, cheap computer that can be plugged into the TV and a keyboard, and can be used as a regular desktop. The board consists of a Broadcom BCM2835 SoC, which includes … Read more
In 2018, the final version of the Raspberry pi 3 Model was launched known as Raspberry pi 3 Model B+. Like every other Raspberry Pi board, R-Pi 3 B+ is a single-board computer. But it has a fast and power-efficient 1.4 GHz processor (1.2GHz in model B) and a faster gigabit Ethernet (it’s limited to … Read more
The Raspberry Pi 3 Model B is a single-board computer developed by the Raspberry Pi Foundation. This board consists of a 1.2Ghz 64-bit quad-core ARM processor and an 802.11n Wireless LAN, Bluetooth 4.1, and Bluetooth Low Energy. Like the previous version (the Pi 2) it consists of 1 GB of RAM, 4 USB ports, and … Read more
Raspberry Pi is a mini single-chip computer. It is developed by the Raspberry Pi Foundation in the United Kingdom along with the association of Broadcom. 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. Raspberry pi Zero … Read more
The Arduino Leonardo is a microcontroller board based on the ATmega32u4 microchip. The Atmega32u4 comes with a built-in bootloader, which makes it convenient to flash the Arduino board with our code. It consists of a total of 20 digital I/O pins (of which 7 can be used as PWM outputs and 12 as analog inputs), … Read more
