PCBs complete
=============

![]({{ site.url }}/assets/platinenkomplett.jpg)

* the yellow PCB on the left is the WIFI antenna
* the green PCB on the right is the FM antenna
* the small metal thingy right of the display is the [FM tuner](http://www.germes-online.com/catalog/80/383/page3/199471/fm_tuner.html)
* the black thingy left of the display is the IR receiver


Main PCB
========

![]({{ site.url }}/assets/hauptplatine.jpg)

* 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
