Prototype 3G USB Model to Serial Converter


Background of this project

The main purpose of this project is to control an embedded system using GSM SMS system. In Malaysia the GSM Modem <-> Serial is rather costly for experimenting. However there are many used 3G USB modem which is available in "ebay" and "lelong.com.my".

So out came this idea to use a USB modem instead of a costly specific Serial Inteface GSM modem.

The first Scale Down Prototype


After successfully working on the starter kit (PIC24FJ256GB106), it is time to make the real prototype using a much smaller size PIC.

This week is long holidays in Malaysia. After this week, will place an order to Farnell Malaysia to purchase the PIC24FJ64GB002 to make this prototype.
