Level Shifters - and more... Hello my friend! We just wanted to let you know that SparkFun will be closed on 12/25/2017 and 12/26/2017 in observance of the
2/5/2016Taking It To Another Level: so we’re going to take a look at the world of level shifters, Will my 5V Arduino harm this 3.3V sensor?
This chip performs bidirectional level shifting from pretty much any voltage to any voltage and will auto-detect the direction.
Seeing a 1 star review surprised me. I have not had any hardware problems with this. It can be connected directly into the i2c of either Arduino and Raspberry Pi
Voltage level translation, or level shifters, will solve the incompatibility between different devices supplied by different power domains. View a comprehensive level
Using the ESP8266 WiFi Transceiver module with a 5v Arduino requires the use of level shifting circuitry. A resistor divider (1k and 2k typically) works perfectly
