Integrate ExpressLRS TX module support and its stacked ESP32 heap changes. Use the approved Linkflow calibration (17-30 dBm), preserve the PA drive and output path after radio recovery, and keep LoRa OTA enabled. Preserve stored ACLs and filters on allocation failure, release owned client/filter buffers, service heap OTA contexts on Companions, release self-serving workspaces after TempRadio, and reset staged-resume state when a context is released. Keep manual staging and active operations alive. Account for all moved allocations in the runtime RAM gate. Validation: 1,393 native cases; radio-power, heap-context, ACL persistence, shared-queue transfer, display/inbox, radio receive, and memory regressions. Firmware builds passed for Linkflow, Heltec V2 Companion, T-Beam MQTT repeater, Heltec V4 R8 MQTT repeater, RAK4631 repeater, and Indicator Full. Physical verification awaits access to the currently offline lab Pi.

; GEPRC LINKFLOW 900M TX - an ExpressLRS 900 MHz transmitter module.
|
|
;
|
|
; ESP32-D0WDQ6, 4 MB flash, SX1276 driving an external PA whose gain is set
|
|
; from a DAC pin. The board itself is a plain ExpressLRS TX module, so the
|
|
; two classes it uses are shared:
|
|
;
|
|
; helpers/esp32/ELRSTxBoard.h fan + backpack + no battery
|
|
; helpers/radiolib/DacPaSX1276Wrapper.h DAC-controlled amplifier gain
|
|
;
|
|
; Every pin below is the value from the ExpressLRS hardware layout for this
|
|
; module - ExpressLRS target "GEPRC LINKFLOW 900M TX", firmware
|
|
; Unified_ESP32_900_TX. The current approved power calibration is cited in
|
|
; target.cpp. Two entries in that layout are deliberately unused:
|
|
; serial_rx/serial_tx (both GPIO13, the inverted half-duplex CRSF link to the
|
|
; handset) and the backpack UART on GPIO16/17.

-D PIN_PA_APC2=26
|
|
|
|
; These numbers are dBm at the antenna, i.e. after the amplifier. The
|

; SX1276 itself sits at a fixed +2 dBm; see DacPaSX1276Wrapper.h.
|
|
; 17 dBm (50 mW) is the stock ExpressLRS "power_default" for this board.
|
|
;
|
|
; LORA_TX_POWER must stay within 2..17. CustomSX1276::std_init() passes it
|
|
; straight to RadioLib's begin(), and PA_BOOST rejects anything outside that
|
|
; range, which would fail radio_init(). It only sets the startup level;
|
|
; MIN/MAX below are what bound the range at runtime, and those go through
|
|
; the DAC, so they are free to be higher.
|
|
;
|
|
; MAX_LORA_TX_POWER is defined once and used twice: the CLI validates
|
|
; against it, and target.cpp hands the same value to the wrapper, which
|
|
; enforces it in applyCachedTxPower(). The wrapper also refuses anything
|
|
; outside its own table regardless, so a board that omits these flags is
|
|
; still bounded by what the amplifier table actually describes.
|
|
;
|
|
; The amplifier will do 33 dBm (2 W), but ExpressLRS only ever asks for that
|
|
; in short packet bursts. MeshCore transmits for far longer, so the ceiling
|
|
; here is one table entry lower. Raise it to 33 only with cooling you
|
|
; trust, and check your local duty-cycle and EIRP limits first.
