Level Shifter Breakout - 5V - 3V voltage level converter - STEMMA QT / Qwiic - Adafruit 5637

The Adafruit Level Shifter Breakout is a voltage level converter that allows you to obtain a 3V output voltage from an input voltage in the range of 3V to 5V . It has a built- in 3.3 V voltage stabilizer with a capacity of up to 500 mA , allows you to connect modules powered by 5 V with sensors with a working voltage of 3.3 V. Level Shifter Breakout has outputs in the form of solder pads, as well as two STEMMA QT / Qwiic connectors , so it can be used with peripheral devices equipped with this connector standard - no soldering required.

Level Shifter Breakout - voltage level converter 5 V - 3 V - STEMMA QT / Qwiic - Adafruit 5637.

The module has outputs in the form of soldering pads, to which the goldpin connectors included in the set should be soldered. Alternatively, STEMMA QT / Qwiic connectors can also be used, which do not require soldering. The converter should be connected with the selected modules in accordance with the following description of the pins:

• VIN / 5V - 5V input voltage pin
• 3V3 - 3.3 V output voltage pin
• G - mass of the system
• 5CL - I2C clock line of input voltage from 3 V to 5 V
• 5DA - I2C data line of input voltage from 3 V to 5 V
• 3CL - I2C clock line of 3 V output voltage
• 3DA - I2C data line of 3 V output voltage
