Product description
SparkFun bi-directional level shifter for safe level conversion between systems such as 3.3V and 5V. The module can both step down and step up logic levels simultaneously on the same channel and is suitable for applications such as I2C, SPI, UART, and 1-wire. The design is based on BSS138 MOSFET transistors and also works with 1.8V and 2.8V systems. Supplied with pin headers (not pre-soldered).
