+- v1.0 and v1.1 boards have a minor error in that the v_lipo sampling resistors
+ are on "the wrong side of the cut" if you try to use a separate pyro battery.
+ The workaround is to cut that trace and put in a jumper, which pretty much
+ requires "return to Bdale for rework". We should fix this for a future PCB
+ revision.

+- 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!
