A tri-mode embedded controller architecture combining ESP32-S3-based signal conditioning and communication control with RP2040 running GP2040-CE for deterministic USB HID output. The system supports UART (wired), ESP-NOW (encrypted wireless via dongle), and BLE modes, enabling flexible low-latency operation with 1000Hz performance.
