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.

Fast shipping and well packed
Arrived quickly. Anti-static bag was a nice touch. Board looks high quality with clear silkscreen.

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.

Solved my I2C issues
I was having trouble with voltage levels on my I2C bus. This board cleaned up the signals immediately. Highly recommend.

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