The IIC/I2C serial interface adapter module is a clever little unit for 1602 and 2004 LCD displays, to minimise the number of wires needed to connect a 1602 LCD to your Arduino. This is done by translating serial input over just a few wires into parallel input that will then be sent to LCD Displays .

This post describes how you can connect multiple Arduinos together via an RS485 connection. This is useful in situations where you need to connect devices together over longer distances than I2C or SPI can handle.

We are proud to introduce the hardware Ethernet Tap — a new member to the IO Ninja Tap family, together with Serial Tap and I2C/SPI Tap. These devices are simple yet functional and convenient sniffers for Ethernet, asynchronous serial links (RS232, RS422, RS485, TTL-level UART), I2C, and SPI communications.

Jul 14, 2017 · A RS485/Serial/I2C/SPI controlled 6 channel Relay with built in ATtiny2313 controller and LM7805 power supply system for home automation or electrical equipment control.The board can control upto 6 relays using serial (TTL Serial,I2C or SPI) or RS485 connection thus saving the precious pins of your microcontroller.The board can be used along with Arduino, AVR or PIC boards.

I have some I2C sensors which are capable of running from low supply voltages. Host microcontroller has 3,3 or 5V supply, which is usually out of absolute maximum range, when I2C device is supplied with e.g. 1,8V. The sensor is usually very low power, which means simple emitter follower could do the low voltage supply.

RS422 was produced to meet such requirements, but over time it has been found that RS422 cannot be used to construct a true multi point network. Enter RS485, which meets all the requirements of a truly multi point network. RS485 specifies up to 32 drivers and 32 receivers on a single bus. RS485/Serial/I2C/SPI Controlled 6 Channel Relay Control Board. The software can be used as a starting point for controlling PLC's from your PC over RS485 link or developing SCADA software. data received by MAX485 through the RS485 link is sent back to the PC using the RXD pin of FT232.

A I2C bus is a bidirectional two-wired serial bus which is used to transport the data between integrated circuits. The I2C stands for “Inter Integrated Circuit”. It was first introduced by the Philips semiconductors in 1982. The I2C bus consists of three data transfer speeds such as standard, fast-mode and high-speed-mode.

I²C (pronounced I-squared-C) created by Philips Semiconductors for use in communication of peripheral devices within a TV-set and commonly written as ‘I2C’ stands for Inter-Integrated Circuit and allows communication of data between I2C devices over two wires. I²C is sometimes called Two Wire Interface. § I2C & SPI & 1-Wire Bus I2C, SPI, 1-Wire and other Serial buses can be read using the I2CChip products "I2C2PC" and the "BL233B" IC. Realterm cannot read I2C without these external devices. It cannot use printer ports, the PC's SMBUS interface etc. The provides a USB/RS232 interface to 3 I2C buses. Realterm is an easy way to use it.
