Principally I like the I2C bus, and it is very widely used to talk between components ... technically we provide that 12V on either side of the extender and bridge it with this jumper to the other ...

"Can TCA9517-Q1 extend I2C bus to 5M length?" It depends on the cable you are using. With cat5 cable, the parasitic capacitance is about 50pF/m. At 5 meters we can expect 250pF of capacitance. TCA9517 ...

It is the reimplementation of the standard Arduino LCD library, configured to work with parallel HD44780 compatible LCDs, and interfaced via a Chinese PCF8574 I2C serial extender. *) The function is ...

The MCP23017, a 16-bit I2C GPIO expander, has always been a tasty chip. With 16 GPIOs addressable over I2C, proper push/pull outputs, software-enabled pull-ups, eight addresses, maskable ...

I'm looking to create an I2C link which will operate over approximately 5m of cable, the P82B96 looks like a good choice for this. The extended I2C lines will not constantly operate as I2C, but for ...

[Roman Dvořák] from ThunderFly has experienced it on their drone building journeys, and that’s why they bring us two wonderful open source hardware boards: an I2C bus extender, and an I2C ...
