---+!! The custom dock for the Gigabeat F and X %TOC% ---++ Introduction The aim of project is to create custom hardware to connect to the Gigabeat F and X. It has the potential to add many more features than are currently available with the official cradle. Check the [[GigabeatPortPins#Dock_connector][dock pinout]] for all the signals which are available. The connector we need to get hold of is the QL11203-C638-7F from Foxconn. It's the same connector used for the Toshiba PDA E800. (Note that although the E800 data cable will fit the gigabeat dock connector it is [[http://pinouts.ru/PDA/toshiba_e800_pinout.shtml][wired differently]] and will damage a gigabeat without modification) This is a good connector for the project. see [[http://www.rockbox.org/twiki/bin/view/Main/SpareParts]] for price and order info. * connector.jpg: <br /> <img src="%ATTACHURLPATH%/connector.jpg" alt="connector.jpg" width='285' height='315' /> ---++ Posible features * USB host without a charger * digital audio in and out (i2s, spdif, optical, coax) * remote control * recording (requires ADC on the dock) * FM radio * Car dock station : * charger * audio out * remote control * automatic volume control with integrated microphone on the dock * Adapter Gigabeat connector to ipod connector to use the ipod stuff * Maybe a TV input? ---++ Todo * To developp all these interfaces, we need to have a breakout box which should give access to all the signals available on the connector : * All standard signal connected to standard connector ( usb , analog audio, power plug ) * All other signal available on a pin connector (i2c, I2s, analog input, gpio) * The power for the usb host can be include on the board or be external. * We will use kicad ( http://www.lis.inpg.fr/realise_au_lis/kicad/ ) to design these boards. ---++ Mods to the official cradle ---+++ Digital in and out A chip which could be used to add S/PDIF-in and -out to the Gigabeat cradle is the [[http://wolfsonmicro.com/products/WM8804/][Wolfson WM8804]] the I2S and I2C pins are availale on the dock connector and the 3.3V is available on the board (used by the [[http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c65640a_8.pdf][Cypress CY7C65640A]] 4-port USB hub) ---++ Links Some [[http://www.minidisc.org/part_hacking.html][hardware hacks for MiniDisc players]]. See for example the "Adding Digital I/Os" links.
