Phico D0 94v0 Lcd Display Datasheet Pdf __full__ Jun 2026
The "PHICO D0 94V0 LCD Display" is a phantom product that exists physically but not in formal documentation. The string "94V0" is the only technical guarantee, certifying the PCB as flame-retardant. The "D0" likely signifies a minor mechanical variant of a standard HD44780-compatible character LCD. While a dedicated datasheet for "PHICO" cannot be produced, the device can be successfully driven using generic LCD library examples for Arduino or PIC microcontrollers. Ultimately, this query demonstrates that for generic displays, the UL safety rating on the PCB is often more reliable than the missing brand name on the label.
Standard HAL drivers for the HD44780 interface are widely available in C/C++. If you'd like to proceed with your project, let me know: phico d0 94v0 lcd display datasheet pdf
A : The extra pins may be for features like buttons, LEDs, or multiple backlight anodes/cathodes. For the 24-pin display, only 16 pins are used for the LCD itself, with the others connected to buttons and LEDs. The "PHICO D0 94V0 LCD Display" is a
If the model number on the PCB is unreadable or scratched off, look at the black epoxy blobs (Chip-on-Board design) or the physical integrated circuit chips mounted on the display. Finding a chip stamped with HD44780 , KS0066 , ST7066 , or S6A0069 means you can safely use any standard HD44780 character LCD datasheet to determine timing protocols and command sets. While a dedicated datasheet for "PHICO" cannot be
Modules matching the PHICO design typically feature a single row of 14 or 16 interface pins. If your board has 14 pins, it lacks a backlight. If it has 16 pins, pins 15 and 16 power the background LED.

How to Interface the Phico LCD
The "D0 94V0" marking identifies a high-quality, flame-retardant PCB used in an LCD module. If you need to drive this display, identifying the onboard controller chip (usually a large IC on the back of the glass or PCB, e.g., S6B0067, ILI9325, or an FPGA) will often yield a datasheet that is compatible with your specific wiring code, even if you cannot find the exact Phico PDF.
