Review on DFROBOT Gravity: 1602 LCD Keypad Shield For Arduino - Simplify Your Arduino Projects with LCD Display and Keypad Interface by Edward Perez
Works great with Nucleo F401RE
Very good quality. Clear screen printing and good soldering. The LCD has no problem with the 3.3V logic level. All buttons read with separate analog values and the reset button also works. Using mbed OS 5 and TextLCD library for control. And since the Nucleo is 5V tolerant on all pins, the 5V VCC taps can be used without level shifters. It's kind of ironic that the mbed ecosystem has an ARM board that is more compatible with Arduino than Due or Zero.
- Operating voltage: 5V
- Only available in white
