Here is a library suitable for use with Cadsoft Eagle pcb software.

Oncore Header - Just the 10 pin 0.1" header, suitable for a straight ribbon cable.
Oncore (Oncore GT) - Can be used as an under-pcb mount layout, ie, pin socket on underside of pcb facing down. (Deriviative of original part in 'Motorola' library)
Oncore (Oncore_mount) - Mirror of above suitable for mounting Oncore face down on component side of pcb.
Trimble_SV6, ACEII, ACEIII (Trimble_SV6,ACEII,ACEIII_mount) - Face down top side mount for said Trimble devices.



Note - Only "Oncore Header" physically tested in circuit so far. I've 'tested' dimensions against modules using laser printout and it seems to fit. I've verified pad connections against pdf specs, but a second pair of eyes would be nice. (Especially SVee6). Please let me know of any problems. (And sucesses )
