TXS0108E High Speed Full Duplex Bi-directional 8-channel Logic Level Converter
Because the Arduino are 5V devices, and most modern sensors, displays, flash cards 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. This board perform bidirectional level shifting from pretty much any voltage to any voltage and will auto-detect the direction.
TXS0108E level shift board features:
VCCA voltage: 1.2V-3.6V;
VCCB voltage: 1.65v-5.5v
Supports 3.3-5V, 1.8-3.3v and other common lever switch;
Applicable to 5V microcontroller and 3.3V module;
Supports level switch between microcontroller and SD card, IIC, SPI;
