 - chatted with Adrian some yesterday.  He likes a Bosch pressure sensor that
   is DK 828-1005-1-ND .. i2c output, similar range to our current part but
   smaller, around $5 at our build quantities.

+- the Johanson balun/filter for 70cm use with cc1111 is DK 712-1540-1-ND
+  uses less PCB area, but lower performance than the discrete approach

+- noodling over TM v2.0 .. baro sensor will be hard to handle on cc1111.  So,
+  how about 48-pin version of STM32L, cc110L radio, ms5607 and MMA665X accel.
+  Move to the faster lipo charger, too.
+	radio / flash on spi2, sensors on spi1, baro on spi1 alternate pins

+- serious stab at what should be on TeleMetrum v2 .. used cc115L section from
+  TeleGPS since I didn't have a cc110L data sheet on the plane .. hope it's
+  similar .. need to update to transceiver, not just transmitter!
