Orchard is a Kinetis-W based platform that is currently in engineering development. More descriptive information of the platform will be released later.
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 | bias OK | power comes up, can show random data and image quality is about right. Some issues with bus read/write need debugging, probably firmware issue. Good enough to have confidence to do DVT. | |
| UART | OK | Works well enough for chibiOS | |
| Integrated radio | |||
| BLE | |||
| Accelerometer | OK | ||
| Microphone | ECO1 | Schematic symbol mirrored; requires board respin | |
| 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 |
