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.
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).
