I can’t execute project edits right now because this account has no available ACUs, so AI design actions are unavailable.
Current project state:
- New empty project created:
Variable Teal R2-D2
- No components, nets, schematic, PCB layout, or documentation have been added yet.
What remains to build your sensor node:
- Select the Wi-Fi + BLE MCU/module, likely an ESP32-class module for 2.4 GHz Wi-Fi b/g/n + BLE 5.x.
- Select a digital temperature/RH sensor, likely I²C.
- Design USB-C 5 V input with CC pull-downs, reverse protection, OVP, UVLO, OCP/current limiting, and 0.5–3 A source tolerance.
- Add 3.3 V regulation sized for Wi-Fi TX current peaks.
- Add schematic, decoupling, programming/debug access, test points, bring-up notes, regulatory notes, and PCB antenna keepout/layout constraints.
Once ACUs are available, I can create the full schematic and supporting project docs.
