 - **LF clock**: internal RC (`USE_LFRC`) - RF-BM-ND05 has no 32.768 kHz crystal; using
  `USE_LFXO` without a crystal makes SoftDevice hang in `RTC1_IRQHandler` waiting
  for LFCLK, causing LED-stuck-on and silent BLE failure.
- **LoRa**: multi-module compatible (SX1262 / SX1268 / RF95 / LLCC68 / LR1121 / LR2021) with TCXO
+- **LoRa**: E22-400M33S (SX1268 + 33dBm PA, 2W, 433MHz) - `SX126X_MAX_POWER=8`,
+  `TX_GAIN_LORA=25` required (22dBm default overdrives PA to ~47dBm, causing current
+  spikes and system reset even at low tx_power settings)
 - **GPS**: u-blox (no EN pin)
 - **Battery ADC**: 0.5 voltage divider (equal resistors)
