Unused Silicon Zones
MT8127D
- Camera ISP (2 × Cortex-M0 + ISP pipeline): Present, not used — no camera interface wired
- Audio DSP block: Present, partially used (HDMI audio encoding); I²S output block unused
- USB PHY OTG portion: USB HS PHY present; OTG detect/host mode unused (no data wiring)
- NAND/SD controller alternate mode: Only eMMC used; raw NAND and SD modes unused
- JTAG TAP controller: Present in silicon, not accessible (no populated header)
- Thermal sensor: Present, running (thermal throttle active), output not exposed to user
BCM43569
- WiFi Direct P2P stack: Full 802.11 P2P in firmware, not enabled in FireOS
- TDLS peer link: Hardware + firmware capable, disabled
- BT RFCOMM serial port profile: SPP present, not exposed
- BT HID host mode: Present, used only for remote; expanded HID not exposed
- 802.11ac 80MHz mode: Hardware may support; 40MHz max in this implementation

Note: Input is 5V @ 1A = 5W max. Full load draws ~2.7W, leaving ~2.3W headroom.
This explains why the device is warm but not hot under streaming load.
