- Clip requested power to the active PA's range instead of failing. A
stored 22 dBm was rejected at 2.4 GHz (HF PA max 13 dBm), and since
setTxPower ignores errors the sub-GHz PA stayed configured.
- Re-apply the requested power after every successful retune: PA choice
depends on the band, and set radio / tempradio only call setParams.
ESP32-S3FH4R2 (4MB flash, 2MB PSRAM, native USB-CDC) with an LR1121.
Pins, the DIO5/DIO6 RF switch table and the 1.8 V TCXO follow the HF
schematic and Waveshare's examples. Envs: repeater, room server,
companion USB/BLE and KISS modem, all on min_spiffs so roles share one
partition layout.
Only RFO_HP_LF is wired (R4 on RFO_LP_LF is not fitted), so the new
opt-in LR1121_FORCE_HP_PA flag keeps RadioLib on the HP PA at <= 14 dBm,
where it would otherwise select the unconnected LP PA.
The major rev from 19.x to 20.x breaks Radiolab, so pin it for now. This should fix the failing wio-e5-mini_repeater builds.
ltoa is removed upstream, so it was replaced with snprintf. The p[] buffer is always 16 bytes. Copy/paste for why claude thinks this is fine below, but also if this is broken it wouldn't be new.
```
exp2 in [23, 30] (int_part = mantissa << (exp2 - 23)): this is where int_part can reach its true max, up to 2,147,483,520 — 10 digits. That's what the snprintf bound of 11 (10 digits + NUL) is sized for. But in this branch frac_part is never assigned anything other than its initial 0, so only *p++ = '0' runs for the fraction — 1 char, not 7.
exp2 in [0, 22] (int_part = mantissa >> (23 - exp2)): this is the only branch where frac_part can also be nonzero and enter the 7-digit loop. Here int_part < 2^23 by construction, so it's capped at 7 digits, never 10.
```
One nRF52840 variant shared across both radios, picked per env: Duo runs
the LR1121, Uno the SX1262. Same PCB, only the radio and its DIO1 pin
change.
SuperIO adds the SH1107 OLED, GPS, buzzer and joystick. GPS is driven by
the 3-position mode switch (Mode 2 = on), polled live the way thinknode_m1
does it.
Five quick user-button presses power the unit off; a press wakes it back
on (arms the button as an nRF52 GPIO SENSE source before SYSTEMOFF).
Consolidates #2054 and andyshinn's shared-base/uno work, rebased on dev.
