Product Description:

Description:

– Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flashcards, and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.
– Here we’ve got a 4-channel I2C-safe Bi-directional Logic Level Converter that has open-drain-with-10K-pullups outputs, great for logic level conversion of interfaces.
– This breakout has 4 BSS138 FETs with 10K pullups. It works down to 1.8V on the low side, and up to 10V on the high side. The 10K’s do make the interface a little more sluggish than using a TXB0108 or 74LVC245 so we suggest checking those out if you need high-speed transfer. Also not good for driving loads from the high side, this is logic level conversion only.
– While we designed it for use with I2C, this works as well for TTL Serial, slow <2MHz SPI, and any other digital interface both uni-directional and bidirectional. Comes with a fully assembled, and tested PCB with 4 full bidirectional converter lines as well as 2 pieces of a 6-pin header you can solder on to plug into a breadboard or perfboard.
