Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month 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... Read more
Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:Really nice form factor, plug it in your breadboard and do whatever you want. Does what it is designed to do. Converts signals from 3.3V to 5V. Tested with Arduino and pinguino with I2C humidity sensors, gps, motorola C115 LCDs and a lot of devices that runs on... Read more
Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:It works exactly as you would expect: connect 5V and GND to one side, 3.3V and GND to the other, and you can shift up to 4 bidirectional signals between 3.3V and 5. This adapter is a must-have if you're working with 3.3V boards like the Raspberry Pi. I've had one conver... Read more
