Gumstix Overo COMs: 27-pin connector J5 to manage camera controls Last update: April 14th, 2010 to update #6 below.
Important:
1/ Connector J5 on each Overo COM is the 27-pin Hirose FH26-27S connector.
2/ Gumstix sells the FPC for this J5 connector at gumstix.com - click here for the product page .
3/ Each end of the FPC connects to a 27-pin Hirose FH26-27S connector. As such, one end of the FPC would connect to the 27-pin hirose connector on the top of the Overo COM while the other end of the FPC would go into a 27-pin hirose connector mounted on a custom expansion board or camera.
4/ Review I/O overview information posted here.
5/ The J5 connector is a bottom contact connector not top contact.
6/ The physical location of pin 1, 2, 26 and 27 of the J5 connector can be found on the layout PDF for the Overo COM via here.
Some J5 Connector Notes:
1.8V power is supplied by the Overo COM for use on the camera module. This power should not be used as a general supply but only to power a level-shifting transceiver, if needed.
The input range of the supply voltage is approximately 3.3V – 4.2V.
VSYSTEM is power from the baseboard routed through Overo for use on camera module.
The signals of connector J5 are connected directly to the OMAP3503 without buffers.
