20 Pcs 3.3V 5V TTL Bi-directional L0gic Level Converter
A part of the review has been auto-translated.
It comes with two converters in each direction, but each side is labelled TX and RX - use them for what you need. There is an unlabelled pin opposite the "LV" (Low Voltage, 3.3V) pin - that's the "HV" (High Voltage, 5.0V) pin.
Ok value for money
Timing and parts are in accordance with the order
Does a wonderful job of level converting
Superbe matériel
Excellent product for FPGA circuits
Does what it should do ...
Item is as specified
These days bi-directional (I2C) converters come six on a board. These are good little boards, they do the job, but if you have a lot of logic to translate, it might be better to look for the hex converter.
Good price for it, very useful for many applications and practice.
