Keith found gps active antennas with cable to U.FL connectors and Molex sells
cables with U.FL to bare leads, so this should cover the bases.
-- TelePyro doesn't need a CPU. How about an SPI to I2C converter chip with
- GPIO lines and an I2C ADC chip?

+ PIC16F882 in SSOP-28 is $2.10 per, 1.41 @ 25 units
+ -- PIC16F883 is $2.12, PIC16F886 is $2.32, have better memories
+ CP2120 in QFN-20 is $2.41 per, 2.27 @ 25 units
The Silabs CP2120 has 8 gpio lines but is only available in QFN20. The NXP
part I discovered earlier, the SC18IS600, has 4 full gpio lines and 2 lame-o
- another way to think about all this is that I could panelize a set of boards
all done in 2 layers, then treat that as a sub-panel I put N copies down of
to fill up a 33each.com max panel size.

+- move to AT45DB161D 16-megabit SPI "DataFlash" EEPROM from Atmel?
+ AT45DB161D-SU-ND in SOIC-8 for $2.26 each
+ appears to compare favorably against $4.40 for current 128kx8 part
+ minor concern about write power, but probably red herring
