Good board, tight pins

The functionality is spot on. The header pins were a bit tight for my Dupont connectors, but once seated, connection is solid.

Perfect for 3.3V to 5V logic

Works exactly as expected. Used it to interface an ESP32 with a 5V sensor array. Stable signal translation.

Great for learning

Using this for my university project. Documentation online is good, board is easy to integrate into breadboards.

5 FAQ

Q: Are the terminals screw type or pin headers?

A: This version comes with standard 2.54mm pin headers for breadboard use.

Q: Does it work with 1.8V logic?

A: VCCA supports down to 1.65V, so 1.8V logic is compatible on the A side.

Q: Is there a voltage regulator onboard?

A: No, this is a level shifter only. You must provide stable VCCA and VCCB externally.

Q: What is the maximum data rate?

A: The SN74LVC4245A supports up to 24 Mbps at 3.3V.

Q: Can this handle bidirectional communication?

A: Yes, the DIR pin controls the data direction dynamically.
