Create a schematic for a low-power LoRa sensor node using ESP32-WROOM-32, RFM95 868 MHz, DS18B20 and 2× AA Lithium batteries.
Thought for 2 sec
No schematic changes were made; the project remains empty with 0 components and 0 nets. Execution is blocked because the account currently has no available ACUs.
Remaining work:
- Define a suitable 2×AA power architecture for the ESP32-WROOM-32 and RFM95 current peaks.
- Add ESP32-WROOM-32, RFM95 868 MHz, DS18B20, battery input, regulator, decoupling, antenna interface, programming header, and protection.
- Wire SPI, 1-Wire, reset/boot, interrupt, and power nets.
- Verify pin assignments, peak-current capability, ERC, and low-power behavior.
