@@ -8,7 +8,9 @@ DIY Meshtastic node variant based on the RF-BM-ND05 nRF52840 module.
- **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)
