Boards driving an external PA can define SX126X_NO_POWER_OPTIMIZATION_TABLE to use the fixed PA config instead of RadioLib's table, which is tuned for a bare SX126x. Default behaviour is unchanged. init() applies the fixed config after begin(), which programs power through the table.
nRF52840 + SX1262 with a 1 W external PA, L76K GNSS, SH1106 OLED. Uses hw_model 144 (meshtastic/protobufs#1038), opts into SX126X_NO_POWER_OPTIMIZATION_TABLE and declares SX126X_MAX_POWER explicitly. The PA gain table is indexed by SX1262 output power in dBm. Requires protobufs#1038 and a protobuf regen before it builds.
Carries the current LR11x0 and LR2021 fixes.
PIN_QSPI_* are logical pin indices. The QSPI flash sits at D19-D24 in variant.cpp, but the defines carried D21-D26 from seeed_solar_node, where that block does start at D21. D25 and D26 are trackball pins. Also replaces mis-encoded characters in the pin comments and drops the migration note, which referenced a private repo path and a stale PINS_COUNT.
board_level = pr is the high-attention tier that builds on every PR. This board belongs with the mainline set, which uses board_level = release.

Bench measurement of the TX curve on hardware, covering the "TX power values still need bench confirmation against measured output" item. Setup

Findings
Caveat on the absolute figure. This meter's no-signal floor reads +5.12 dBm on the 900 MHz curve where the instrument spec is ~−25 dBm, so absolute dBm here rests on inferring a +30.1 dB instrument offset and assuming the pad is exactly 30.0 dB. Combined uncertainty is ~±1 dB, which is the same size as the offset being measured. The 1:1 tracking result is relative and unaffected by this. Suggest treating the table's shape and magnitude as confirmed, and holding the −1 dB adjustment until it can be repeated against a calibrated reference.
