pinout - Is there any definitive I2C pin-out guidance out there?
WEBNote that "Grove" connectors are standardised as 4-pin with a particular connector, but have a variety of incompatible electrical interfaces, we're specifically talking about the I2C ones here. These use a different connector, but they use the same pinout as Stemma.
The Connector Zoo: I2C Ecosystems - Hackaday
WEBMay 4, 2022 — There’s two ecosystems of I2C modules that are based on four-pin JST-SH (1mm pitch) connectors, and they’re very interchangeable! One of them is Sparkfun’s QWIIC, and other is Adafruit’s STEMMA...
Arduino - LCD I2C | Arduino Tutorial - Arduino Getting Started
WEBLCD I2C uses I2C interface, so it has 4 pins: GND pin: needs to be connected to GND (0V). VCC pin: the power supply for the LCD, needs to be connected to VCC (5V).
I²C - Wikipedia
WEBI2C (Inter-Integrated Circuit; pronounced as “ eye-squared-see ” or “ eye-two-see ”), alternatively known as I2C or IIC, is a synchronous, multi-controller/multi-target (historically-termed as master/slave), single-ended, serial communication bus invented in 1982 by Philips Semiconductors.
