 > **Heltec Mesh Node T096** (`heltec_t096`): nRF52840 with SX1262 + KCT8103L PA/FEM, UC6580 GNSS, and ST7735S 160x80 TFT companion display. The external SPI flash footprint is documented in the board notes but left disabled until the device parameters are confirmed.

+> **Heltec Mesh Node T1** (`heltec_t1`): nRF52840 + SX1262 handheld tracker card with UC6580 L1+L5 GNSS, ST7735S 160x80 TFT, PAM8904-driven piezo buzzer, two buttons and a 1850 mAh battery. No PA/FEM — the SX1262 drives a uPG2179 antenna switch from DIO2. The onboard ICM-42607-P/MMC5983MA IMU bus is left powered down (no ZephCore consumer). Untested on hardware; the GNSS UART direction and the display offsets are the two things to check first, both flagged in the board README.

 > **LilyGo T-Impulse Plus** (`lilygo_timpulse_plus`): nRF52840 wristband/tracker with SX1262 (GPIO antenna switch, not DIO2), SSD1315 64x32 OLED, u-blox MIA-M10Q GPS, 4 MB QSPI flash (`/ext`), touch button, haptic motor. Builds and ships in releases, but several parameters are inferred from vendor sources and not bench-verified (TCXO voltage, battery divider ratio, OLED offsets) — see the board README. Early hardware testing also showed occasional spontaneous reboots, untriaged.

 > **ProMicro LR2021** (`promicro_lr2021`): nRF52840 SuperMini + Semtech LR2021, the first ZephCore board bring-up for that radio. Source-only — **not in `build.sh`, the release workflow, or the Mesh America catalog**, so no release carries a binary for it. The bring-up module was destroyed by an accidental 5V feed (LR2021 VBAT max ~3.7V); build it yourself if you want to continue testing on a fresh module.
