Abstract
Disclosed is the hardware architecture for the ChurchMesh Communicator, a dedicated, ultra-low-power mesh messaging device. The invention details the specific integration of components optimized for long-range, resilient communication: an ESP32-S3 MCU, an E-Ink display (for sunlight readability and zero static power draw), a physical QWERTY keyboard, and an SX1262 LoRa module (10km+ range). The architecture is optimized for 2+ week battery life. The firmware (ESP-IDF + LVGL) utilizes novel power management techniques, including E-Ink partial refresh optimization and aggressive deep sleep modes, waking only on keyboard interrupt or incoming LoRa message. The device integrates "KTKN-Lite" for decentralized synchronization.
