MyIMX233
About the MyIMX233 PCB
MyIMX233 is an open source PCB design by samarjit, published on GitHub. It is a 2-layer board measuring 74.1 × 92 mm, with 101 components from 50 distinct parts.
Other key parts include the iMX233 and DDR_SDRAM_MT46_x16. By type, the board carries 42 capacitors, 27 resistors, 10 diodes, 8 connectors, 2 ICs and 2 jumpers.
From the project
MyIMX233 will be a homemade Single board computer based on Freescale iMX233 and 64MB DDR2 RAM built with KiCad
I am starting to build a single board computer with freescale microprocessor iMX233 128 LQFP and 64MB DDR2 SDRAM in 66TSOP. This single board computer will be bare bones with lots of GPIO exposed. There is no special goal for this project. I am just curious to see if it works. In future I might add an LCD. The PCB is two layered only and can be manufactured cheap.
