2.8Vin to 22Vin, 2A lout, 4-Switch Integrated Buck-Boost Converter with I2C Interface
https://www.electronics-lab.com/2-8vin-22vin-2a-lout-4-switch-integrated-buck-boost-converter-i2c-interface/
Monolithic Power Systems has introduced a new synchronous, 4-switch integrated buck-boost converter, the MP8862. The converter can regulate the output voltage from a wide input voltage range of 2.8V to 22V with high efficiency. The converter supports an Iout of 2A. Vout ranges from a 1V minimum to a maximum of 20.47V with a 5mV resolution […]
I²CDriver – An easy-to-use tool for controlling I²C devices
https://www.electronics-lab.com/i%c2%b2cdriver-easy-use-tool-controlling-i%c2%b2c-devices/
I²CDriver is an easy-to-use, open source tool for controlling I²C devices. It works with Windows, Mac, and Linux, and has a built-in color screen that shows a live “dashboard” of all the I²C activity. It uses a standard FTDI USB serial chip to talk to the PC, so no special drivers need to be installed. […]
I2C GPS Module with NMEA decoding
https://www.electronics-lab.com/i2c-gps-module-nmea-decoding/
David Johnson-Davies designed a GPS module that decodes the NMEA sentences on ATtiny841, and this also runs the I2C slave routine. He writes: This is a compact GPS module with an I2C interface, making it easy to read the GPS parameters from another project without needing to worry about parsing the NMEA sentences. It’s a […]
I2C GPS Module along with ATtiny841
https://www.electronics-lab.com/i2c-gps-module-along-with-attiny841/
This project describes a simple GPS module which you can interface to via I2C. It uses an ATtiny841. David Johnson-Davies writes: Incorporating GPS into a project is quite daunting. First you have to parse the NMEA sentences from the GPS module you’re using, and then if you’re doing any calculations with the received longitudes and […]
Extending I2C communication distance with the DS28E17
https://www.electronics-lab.com/extending-i2c-communication-distance-with-the-ds28e17/
App note from Maxim integrated about alternative method to extend I2C bus. Systems are increasingly requiring greater distances for I2C buses. This article explains how the DS28E17 can be used to extend the distance of I2C devices while decreasing cost. Extending I2C communication distance with the DS28E17 – [Link]
I2C – Everything you need to know
https://www.electronics-lab.com/i2c-everything-you-need-to-know/
I2C – Everything you need to know article from www.mikroe.com There is no need for a wordy introduction to I2C protocol. We all know it’s main parts – 2 wires, multiple slaves, sometimes multiple masters, up to 5MHz of speed. Often so have we all implemented an I2C connection. Still, every now and then, there’s that […]
I2C Encoder V2 – Connect multiple rotary encoders on the I2C bus
https://www.electronics-lab.com/i2c-encoder-v2-connect-multiple-rotary-encoders-i2c-bus/
I2C Encoder V2 is a tiny smart board for connecting multiple rotary encoders on the I2C bus and it’s live on kickstarter. The I2C Encoder V2 supports various type of rotary encoder with one footprint: Standard mechanical encoder Illuminated RGB encoder Clickable rotary encoder With and without dent There are also 3 configurable GPIOs that […]
my-ssd1306 an HTML interface to SSD1306 OLED display
https://www.electronics-lab.com/ssd1306-html-interface-ssd1306-oled-display/
A board that transforms your SSD1306 OLED Display into an RS232 monitor with HTML built-in parser. Now live on kickstarter. My-SSD1306 allows you to connect any device equipped with RS232 to the I2C SSD1306 displays. My-ssd1306 board should be put between the RS232 source and the I2C SSD1306 target. Two series of connection pins are […]
Tiny Graphics Library for ATtiny85 and SH1106 OLED Display
https://www.electronics-lab.com/tiny-graphics-library-attiny85-sh1106-oled-display/
David Johnson-Davies published another great tutorial on how to use the Tiny Graphics Library to plot the outside temperature over 24 hours on a 128×64 OLED display using an ATtiny85. This small graphics library provides point, line, and character plotting commands for use with an I2C 128×64 OLED display on an ATtiny85. It supports processors […]
Isolated Power Supply for RS485, RS422, RS232, SPI, I2C and Power LAN
https://www.electronics-lab.com/isolated-power-supply-rs485-rs422-rs232-spi-i2c-power-lan/
Mini Isolated Power Supply is designed for CAN, RS-485, RS-422, RS-232, SPI, I2C, Low-Power LAN applications. The power supply provides +/- 5.50 V DC symmetrical outputs with load current 500mA from 5V DC input. The project is built using SN6505A IC from Texas instruments. The SN6505A is a low-noise, low-EMI push-pull transformer driver, specifically designed […]
