4. SparkFun Pegelübersetzer Breakout - PCA9306
There are some boards that every engineer and maker should have on their desk, and this PCA9306 dual bidirectional voltage level translator breakout is one of them! Since different components sometimes use different voltage levels to communicate, voltage level translators can be key to ensuring that various components work together.
The PCA9306 is a dual bidirectional I2C bus and SMBus voltage level translator that operates on the low side from 1.2V to 3.3V and on the high side from 1.8V to 5.5V. Simply apply your low and high side reference voltages to VREF1 and VREF2 respectively, connect your I/O, and drive the enable pin high to enable bidirectional voltage translation without the need for a direction pin!
We have updated this classic board to use a new footprint, added a second ground pin, and broken out the enable pin.
5. SparkFun Qwiic - Mux Breakout, 8 Kanäle (TCA9548A)
The SparkFun Qwiic Mux Breakout is a versatile electronics module specifically designed to facilitate communication with multiple I2C devices that share the same address.

6. SparkFun Flex Sensor 2.2 / 5,6cm
A simple flex sensor with a length of 2.2 / approximately 5.6 cm. When the sensor is bent, the resistance across the sensor increases. Patented technology from Spectra Symbol - they claim that these sensors were used in the original Nintendo Power Glove.
The resistance of the flex sensor changes when the metal pads are on the outside of the bend.
The connection is spaced at 0.1 inches and is breadboard-friendly. Please check the datasheet for complete specifications.
Note: Please avoid bending or stressing this sensor at the base. The usable range of the sensor can be bent easily, but care should be taken to minimize bending outside of the usable range. The best results are achieved when the base and the lower part are firmly mounted, allowing only the actual flex sensor to be bent.
