4-Way Bi-directional Logic Level Converter V2

This useful little board provides 4 bi-directional logic level converters and a 3.3V voltage regulator in the one small package. This makes it great for connecting your Arduino (or other) board running at 5V with sensors, microSD cards and other devices that are running typically at 3.3V. With the onboard 3.3V voltage regulator you can power the external devices without needing a separate supply.

This new version of our board is much smaller so takes up less space on your breadboard

Features

  • On-board 3.3V 250mA voltage regulator
  • 4-way logic level conversion
  • Each channel fully bi-directional using mosfets
  • Works with I2C, SPI and TTL logic
  • Breadboard friendly pin connections spaced at 0.1in and 0.5in apart
  • Size: 16mm x 16mm
  • Can be used with 1.8V sensors by removing solder bridge J1

Each mosfet has 10k pullup resistors on the 5V and 3.3V side so it works great with I2C, SPI and TTL.

The four high voltage input lines A1..A4 connect to the 4 low voltage lines B1..B4 respectively.

Although designed for 5V to 3.3V/1.8V conversion, you can use up to 10V on the high voltage side

3.3V Devices

The board has a solder bridge (J1) that links the onboard 3.3V regulator up to the low voltage side. This is the default and allows connection to 3.3V devices and also supplies a 3.3V 250mA output.

1.8V Devices

If you are connecting to 1.8V devices you can removed this solder bridge, thereby disconnecting the 3.3V regulator. You will then need to connect the 3V low side pin to the 1.8V supply on your device to enable pins B1..B4 to be pulled up to 1.8V
