…I commands Add virtual methods to MainBoard (tick, getCustomGetter, setCustomSetter, queryBoardTelemetry) enabling board variants to hook into the main loop, CLI get/set commands, and telemetry queries without modifying core code. - MeshCore.h: CayenneLPP forward decl + 4 virtual methods with default no-op implementations - CommonCLI.cpp: dispatch 'get board.*' and 'set board.*' to board methods - simple_repeater: call board.tick() and board.queryBoardTelemetry() - simple_sensor: call board.tick()

Restructured — commit 1 is now 32 lines of pure extension hooks, no behavioral changes for existing boards |
Inhero MR-2 is a solar-powered LoRa repeater board based on RAK4630 (nRF52840 + SX1262) with BQ25798 MPPT charger, INA228 fuel gauge, BME280 environment sensor, RV-3028 RTC, and hardware watchdog. Key features: multi-chemistry battery support (Li-Ion, LiFePO4, LTO) with Coulomb-counted SOC, MPPT solar charging with adaptive IINDPM, low-voltage sleep with RTC wake (< 500uA), custom CLI commands (get/set board.*), board telemetry, USB auto-management, and hardware watchdog with I2C health monitoring. Full documentation: https://docs.inhero.de

… of the story The "Relation to upstream" section still described the variant as a standalone out-of-tree product fork. That has not been true since 2026-08-08: meshcore-dev#3130 (hardware request), meshcore-dev#3131 (board hooks) and meshcore-dev#3132 (the variant itself) are open upstream, and the fork releases are the interim until those land. It also left the April withdrawal unexplained. The board was not available yet and CE certification was still in progress; both are settled now, which is the reason the variant is being proposed again.
