Key IC selection

main MCU and wireless SOC

• Need: Process sensor inputs, drive defense mechanism actuators, and maintain stable Wi-Fi connectivity in an outdoor residential environment.
• Class: Wi-Fi/BLE enabled 32-bit dual-core microcontroller module
• Shortlist: Espressif ESP32-WROOM-32 series, Realtek RTL8710af series
• Pick: Select commercial-grade ESP32-WROOM-32 variant with integrated PCB antenna and adequate flash memory based on operating temperature range and distributor stock.

Risk register

ID	Area	Severity	Detail	Mitigation
r1	power	high	USB-C power input may suffer from voltage drop and high inductive spikes when driving electromechanical defense actuators directly from the 5V rail.	Isolate actuator power supplies using a separate motor driver power rail with bulk capacitance and flyback diodes, keeping logic power clean for the ESP32.
r2	thermal	med	Enclosed outdoor residential deployment exposes the control board to direct sunlight and high ambient temperatures, potentially causing thermal throttling or Wi-Fi RF degradation.	Ensure adequate thermal relief around the ESP32 module, avoid high-power linear regulators, and use an IP-rated enclosure with proper ventilation or heatsinking.
r3	emi	med	Actuators and defense mechanisms switching near the ESP32-WROOM-32 onboard antenna can induce severe conducted and radiated EMI, dropping Wi-Fi packets.	Route high-current actuator traces away from the RF antenna clearance zone, implement proper ground planes, and add ferrite beads on control lines.

Bring-up and Validation Plan

1. Power-off inspection and rail resistance checks
2. Current-limited first power-up; verify every rail before enabling loads
3. Validate interfaces and timing one subsystem at a time
4. Run thermal, fault-injection, EMC pre-scan, and endurance tests for the target environment
