SunFounder Fusion HAT+ for Raspberry Pi 5/4/3B+ and Zero single board computers is a motor control and GPIO expansion board ...

The PCA9698 is an I2C, 40 pins parallel IO expander. These 40 pins can be configured as INPUT or OUTPUT and are addressable via 5 banks (groups) of 8 IO pins. The library provides read/write access to ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

The I2C and I3C interconnect technologies are close cousins, both conceived as interfaces for short-haul (intra-board) communication between integrated circuits and other digital devices. As we shall ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

The inter-IC bus, or I2C bus for short, is a two-wire bus designed for connecting simple peripherals that do not require rapid transfer of large amounts of data. In this three-part series we will look ...

TM1637 is a kind of LED (light-emitting diode display) drive controller special circuit with a keyboard scan interface. It is internally integrated with MCU digital interface, data latch, and LED high ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your Arduino, or any microcontroller ...

Developers, engineers and Arduino enthusiasts may be interested in a new open source piece of hardware designed for CAN bus Arduino projects. Combining several essential features into one complete ...
