Adafruit QT 5V na 3V I2C - Stemma QT/Qwiic/EasyC

On one side is 5V-safe power and logic input. In the middle is a 3.3V regulator that can provide 500mA plus level shifting circuitry. On the opposite side is the same I2C traffic but now safely shifted down to 3.3V to allow usage with the vast number of sensors and devices that are not 5V safe.

This small and simple module gives us a translation of logic level between two signals. Something like this is useful in this case if we want to achieve communication between two devices with different logic levels. This board is specialized for signal conversion for I2C (IIC) communication protocol.

This board allows you to use I2C over long cables - up to 3m @ 400 KHz and up to 30m @ 100 KHz via Ethernet cable! Just connect it to your I2C bus at the beginning of the chain, no special firmware, software, or configuration required. Runs with any bus voltage, from 1.6V to 5.5V and up to 400 KHz SCL speed, with cables up to 4000pF.

Finally, a way to get up to 4 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected I2C port with your command. Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77 using jumpers on the back) and you simply write a single byte with the desired multiplexed output number to that port.
