1 Features

The key features of the board are: 

STM32 high-density (64 KB RAM, 512 KB flash) microcontroller

320 x 240 pixel resolution parallel-interfaced TFT display

 

using the FSMC peripheral for 

faster display

Bluetooth

®

 module footprint 

S-Touch

 

 

based keypad for user interface

ZigBee

®

 for picture transfer

STM32-based RTC available to display the date/time and calendar

MEMS used to rotate the image as per the TFT alignment

Micro-SD card interfaced through SDIO

USB mini-B connector

Uses the mass storage for connectivity to PC. User will be able to copy data directly 
using USB, hence the card reader functionality

User-programmable time interval for pictures

Temperature sensor senses temp. and  is displayed on the TFT

Onboard power supply for DPF

Rechargeable battery circuit available

Onboard JTAG connector for firmware upgrades and changes

Additional ESD-protection device for USB and SD card
