| [* black] With a bit of patient spudgering, the boards are disengaged—leaving the motherboard stripped and primed for some primo IC analysis: |
| [* red] MAX77836—likely micro-USB interface controller and Li+ battery charger |
| [* orange] 1513E8 E614A6 |
| [* yellow] STMicroelectronics [http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1577/LN1810?icmp=ln1810_pron_nb_apr2013&sc=pr-stm32f401|STM32F401|new_window=true] Cortex M4 microcontroller |
| [* green] Samsung KMF5X0005A-A210 512 MB DRAM package with the Qualcomm APQ8026 System on Chip layered beneath |
| [* blue] Qualcom PM8226 power management IC |
| [* violet] InvenSense [http://www.invensense.com/mems/gyro/nineaxis.html|MP92M|new_window=true] 9-axis Gyro + Accelerometer + Compass |
