+- keithp reports what looks like RF getting into the SPI bus that the cc1120,
+ flash, and companion port are on. looking things over, we should:
+
+ - rotate the cc1120 180 degrees, bringing SPI off the northwest corner
+ and just dealing with the rework that will provoke on the UHF side
+
+ - add 330 ohm / 47pf snubbers on the source end of all SPI lines
+
+ - rework the SPI traces to put the SPI at one end as much as possible
+
+- since MMA6556 remains unobtainium, moving to an Analog Devices part with
+ the 5V switcher may be necessary
+ + elide MMA6556
+ - merge megaaccel content
+
+- cut the big MicroMaTch down to just a 4-pin debug connector for STLINKv2?
+
+- can we use the 64-pin version of the STM32L151?
+ - it looks like the answer is yes, but of course it would require a
+ massive re-routing of the board...
+
++ move the MPU-6000 from I2C to SPI
+
++ leave the mag sensor out
+
+- that leaves nothing on I2C, but if we do use I2C, we need pull-ups!
