1 Introduction

The VI800A-TTLU is a plug in accessory for

the VM800P Plus module, which expands the

IO capabilities of the VM800P to include a

TTL level UART.

This module behaves as an SPI to UART

bridge to the VM800P Plus module.

1.1 Features

 Connects to the VM800P Plus module using

an SPI slave interface

 SPI slave interface is converted to UART

TTL interface

 4 GPIO inputs and 4 GPIO outputs

 8 LEDs to indicate the input and output

status

 5 V tolerant buffers

 Screw connector to connect the UART

signals, GPIO inputs and GPIO outputs

 IO connector to connect the UART signals,

GPIO inputs and GPIO outputs

 Powered from the VM800P module
