The VM800B development modules offer a hi-quality display system in an elegantly designed, form-fitted bezel that provides a fitted display and component board in a rugged, plastic enclosure. Offered in black or pearl colors, this display sub-system provides the engineer a low priced option which can shorten development time while enabling a production finished look. These FTDI Basic modules are designed to control 3.5”, 4.3” or 5” TFT displays.


Detailed Description

Development Module FTDI VM800B50A-PL

Included in the module is a speaker for audio output and a 0.1” pitch connector socket for interfacing to the SPI interface of the system host MCU. There are 5 power configuration methods including a mini-USB socket and a 2 pin DC connector.

  • SPI/I2C interface to host MCU
  • 1.8V to 3.3V IO levels to host MCU
  • 3V3 levels on RGB pins

The VM800B modules has the following features: 

  • Ready to use LCD module.  
  • Integrated with resistive touch screen LCD panel
  • On board LCD backlight LED Driver
  • On board audio power amplifier and micro speaker
  • Flexible power supply. Powering the VM800B using either a 2.1mm power jack , SPI master connector or via USB Micro-B  port 
  • 5 V tolerant buffers when used with a 5V SPI Master
  • Precision fitted bezel in black(-BK)  or pearl (-PL)

The VM800B module is intended for direct use into existing applications that require a display. This module is suitable for interfacing with an external microcontroller that has a SPI Master channel. The VM800B module is available in multiple options: 3.5, 4.3 or 5.0 inch display options.

The main functions of the VM800B are as follows:

  • Micro USB connector
  • SPI connector 
  • 2-pin connector for power supply
  • 3.3V regulator: Takes 5V input and outputs 3.3V for on-board circuits
  • LCD touch screen panel
  • 5V tolerant buffers between the SPI master interface and the Slave interface of the FT800
    • SPI timing requirements can be found in the FT800 datasheet. The on board level converter buffers introduce additional delay. The actual maximum SPI clock frequency depends on the host system timing and connection cable length to the VM800B PCB.
  • 3 stage audio filter and power amplifier
  • 8Ω speaker
  • Audio line out option 
  • Precision fitted bezel
