Main PCB
|
||
|
|
========
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
* on the top are two connectors, an 8-pin (J9) and a 4-pin (J5) one
|
||
|
|
* the 4-pin connector, J5, is the serial console interface, the pins are as follows (left-to-right):
|
||
|
|
* +5V
|
||
|
|
* GND
|
||
|
|
* TxD (from SoC)
|
||
|
|
* RxD (to SoC)
|
||
|
|
* the larger ICs are:
|
||
|
|
* the CPU, a [Lattice 4128V](http://www.latticesemi.com/products/cpldspld/ispmach4000bcv.cfm) [CPLD](http://en.wikipedia.org/wiki/CPLD)
|
||
|
|
* a [IDT 72V04 L35J](http://www.idt.com/?partId=72V04L35J) FIFO chip
|
||
|
|
* a [Princeton PT8406](http://www.princeton.com.tw/temp/products.asp?product_level2_id=42) MP3/WMA decoder
