About the Imx233 gsm PCB

Imx233 gsm is an open source PCB design by karrister, published on GitHub under the Custom license license. It is a 2-layer board measuring 126 × 151.1 mm, with 149 components from 75 distinct parts.

Other key parts include the FREESCALE-IMX233, HY5DU121622D, SMA_JACK, SIM900 and LCD_NOKIA5110. By type, the board carries 55 capacitors, 46 resistors, 29 connectors, 5 ICs, 5 diodes and 4 inductors.

This project started as my thesis project for the University (of applied sciences) of Helsinki. The project is about making a simple open source, Linux based cellular phone. In the heart of the device are an Olimex made Olinuxino (the original) IMX233 development board, connected over an application UART to a SIM900 GPRS GSM-development board. I will also connect a self-made keypad (1 button at first stage) and a self-made screen (1 LED indicator at first stage).
