## UBSEDS2
Launched from EMF 31/08/2014. Joint flight with CUSF (JOEY rtty/turbo)
and SUSF (UKHAS repeater).
AAA battery and surgically attached 16MHz crystal. Measured 80mA
current draw, no power saving for the ublox 6.
Revision C Atmel SAM D20 microcontrollor (bit-banged SPI)
140g free lift on a 100g Hwoyee.
4 hours battery life, much less than expected. Low temperatures?
Watchdog enabled, 64 seconds timeout (based on ULP32k oscillator, so
+-50%)
