USB Sensor Node
Thought for 2 sec
I’m blocked from continuing execution because this account currently has no available ACUs, so AI project mutations and tool-based inspection are unavailable.
What I accomplished so far:
- Acknowledged the design direction for a USB-C powered consumer temperature/humidity sensor node.
- Defined the intended architecture at a high level: USB-C 5 V input, protection/power-path, 3.3 V rail, ultra-low-power Wi‑Fi + BLE 5.x MCU, and digital T/RH sensor.
What remains to be done:
- Review the attached pasted text once ACUs are available.
- Select exact components for:
- USB-C receptacle and CC resistors
- Input protection with reverse/OVP/UVLO/OCP
- 3.3 V regulator sized for Wi‑Fi peak current
- Wi‑Fi/BLE MCU or module
- Digital temperature/humidity sensor
- Create the project specification and schematic.
- Wire power, USB-C default-current behavior, programming/debug, boot straps, decoupling, and sensor interface.
- Run ERC/design review and then proceed to PCB layout with RF antenna keepout and USB-C mechanical constraints.
