Validation Matrix

Validation matrix
Subsystem basic status extended status notes
Kinetis-W CPU OK basic SWIO functions OK, OS operational
WS2812B driver OK confirmed CPU has GPIO performance to operate on-board LEDs; extended chain testing TBD
I2C OK
SPI OK
OLED OK
UART OK Works well enough for chibiOS
Integrated radio
BLE
Accelerometer OK
Microphone ECO1 / OK Schematic symbol mirrored; requires board respin. Tested OK on EVT1b
MPR121 OK
Jog dial + buttons OK OK for direct touch on dielectric. Not yet tested for capacitive projection through ABS bezel.
GPIO expander OK
Fancy battery charger OK
Shipping state power OK OK immeasurable leakage when in "ship mode" e.g. soft battery disconnect state
Gas gauge OK/ECO3 gas gauge itself works fine, talks on I2C; but topological position is incorrect and requires ECO3 to be effective
USB charging port OK
USB charging port OC protect
Cheesy battery charger option N/A not populated in EVT1
Cheesy battery level option N/A not populated in EVT1
On-state power characterization
Standby power characterization

Power Consumption

As measured while on battery, ~3.9V through test.

  • Powered on, 16 LEDs running wave-rainbow at default brightness: 78-79mA
  • Halted (debug mode) 16 LEDs frozen on wave-rainbow: 76.5mA
  • Captouch off: 76.5mA (not measurable reduction)
  • LEDs off: 40mA
  • Accel off: 39.8mA
  • BLE off: 33.1mA
  • OLED off: 58.7mA
  • Boost off: 25.3mA
  • gpiox off: 25.3mA
  • PEE-PBE: 22.7mA
  • PBE-FBE: 22.1mA
  • FBE-FEI: 21.5mA
  • Radio off, CPU halted: 3.0mA

Alt-order:

  • Halted, everything on: 77.5mA
  • Captouch off: 77.4mA
  • LEDs off: 40mA
  • Accel off: 39.9mA
  • BLE off: 33.1mA
  • Boost off: 33.2mA
  • OLED off: 24.7mA
  • gpiox off: 25.3mA or 24.6mA?
  • PEE-PBE: 22.7mA
  • PBE-FBE: 22.1mA
  • FBE-FEI: 21.4mA
  • Radio stop: 3.0 mA
  • CPU halt: (not executed due to bugs)
