lcd module 1602a qapass datasheet pdf quotation

LCD display for replacing a broken one or for creating something new. This LCD display can be used easily with Arduino, Raspberry Pi, Intel Edison or any other embedded system you want to work with.

Due to the ancient LCD controller technology made by Hitachi, the board controller requires 5VDC operating voltage. In order to easily use this display with say Raspberry Pi (3,3VDC) you need to hack this display a bit. In order to make it work with lower operating voltage, add a 8pin voltage converter such as ICL7660 (or similar) onto the space indicated with label U3. Then populate C1 and C2 with 10µF SMD capacitors and remove J1 solder bridge. To finalize the job enable the voltage converter by soldering a solder bridge across the J3 contact pins. You have now an LCD display capable of operating with lover operating voltage.
