If you want to connect 3.3V devices (sensors, memory cards etc.) to a 5V micro controller, or the other way around, you will most likely need level converter. Not many micro controller, running on a 3.3V power supply, can accept 5V signals on their inputs and outputs, without damage.

This tiny board works with max. data transfer rates of 28.8 kBaud, and it operates in both directions the same way (bi directional).

A 3.3V LDO to supply power for the 3.3V logic level outputs is integrated; only a 5V power supply is needed for the operation!

The maximum current for all 4 lines must not exceed a total of 150mA. With this in mind, the board can also be used, for example, to 1 or 2 low power 5V relays on 3.3V output pins.

– power supply 5V, max. 150mA

– on board 3.3V voltage regulator

– 4 bi-directional signal lines

– 3.3V to 5V and 5V to 3.3V signal conversion at max. 28800 bps.

Typical applications are for UART interfaces, 1-wire interface, I2C and SPI interface, Atmel ICSP interface etc.

    I used this to connect the 3.3V I2C lines of an ESP8266 to an LCD display that required 5V to operate. I put pull-up resistors on the SDA and SCL on both the 3.3V and 5V sides.

    Pull-up resistors are already on the module, better not adding extra resistors in parallel. That can worsen the signal stability.
