Great solutions for 3.3V development boards! – JY-MCU 5V 3V IIC UART SPI Level 4-Way Converter Module Adapter Reviews

Pros:
I recently bought an Arduino Due board, of which it's GPIO pins operate at 3.3V, not 5V as other boards do. Instead of improvising a level converter myself, I decided it's best to buy a already made and tested one. Even though it only has 4 bidiractional ports, it's more than 0 that I had. To use it, you only need a 3.3V and 5V supply, and that's it! A red SMD led confirms power is present, so you can start using 5V signal on a 3.3V pin (or vice-versa).
Cons:
None. The fact that it's pins aren't soldered is actually an advantage, considering that some would wish to solder 90 degrees ones, or the cables directly, depending on their applications.
Other:
None so far.
Bottomline:
Great little level converter!
