After experiments with GE865, AT90USB82/162 and NEO-5Q i decide remove CPU and use only USB-USART adapter (from SiLabs CP2102). Schematic more simple and programming with Python. Additional added GPS module power control, two buttons and LEDs.
and board
but after connect to host computer well known programm RSTerm (from roundsolutions.co.uk) not work correctly with SiLabs chip CP2102. For work with GE865 via CP2102 i write own software like as RSTerm (more simplest but without problems with CP2102).

Hi,
Have you thought of producing these to fit into the handle bars of bikes as a theft detection device?
Do you plan to make these (or do you already?)
Hi
it's possible but some limitation
1. internal diameter of handle bar need ~25mm
2. handle bar makes from steel and gps/gsm waves not receive across steel.
As initial i make this device for my son - in schoolbag for tracking position from school to home.
