# Built on the RAK4631 core module with a 30 dBm (1 W) external PA. The SX1262
|
||||
# is driven at the ZephCore default 22 dBm; the onboard PA brings the antenna
|
||||
# output up to ~30 dBm. DIO2 keys the T/R switch, DIO3 supplies the 1.8 V TCXO
|
||||
# (see gat562_30s.dts). Flash layout matches RAK4631 (SoftDevice s140 v6,
|
||||
# app @ 0x26000), so the stock UF2 bootloader is reused — no re-flash needed.
|
||||
#
|
||||
# Most features are auto-detected from devicetree:
|
||||
# - PWM + buzzer (buzzer nodelabel)
|
||||
# - SSD1306 OLED (zephyr,display chosen) -> also UI_DISPLAY below
|

# - LoRa RX duty cycle (companion + SX1262)
