wadamesh incorporates and/or depends on the components below. Their own licenses
are preserved and apply to those portions. MIT and Apache-2.0 are compatible with

MeshCore
Copyright (c) 2025 Scott Powell / rippleradios.com
MIT License — https://github.com/meshcore-dev/MeshCore
wadamesh derives its companion-radio application and core hooks from
MeshCore. The MeshCore-derived source files retain their MIT license
notices. The separate MeshCore fork that wadamesh builds against (the
Wi-Fi/BLE/UI hooks) is published under MIT, not GPL, so those hooks remain
upstreamable to MeshCore.

minimp3 (bundled in lib/minimp3)

Pinned at ea99364f61c14656440e8d77e9c233ccf3124633. The bundled header has
a small opt-in scratch-storage hook so the decoder workspace can live in
PSRAM; default upstream behavior is unchanged when that hook is not used.
AsyncElegantOTA (vendored in arch/esp32/AsyncElegantOTA)

ESP-IDF FatFs component (vendored in arch/esp32/fatfs_exfat, built with exFAT)
FatFs: Copyright (c) ChaN — FatFs license (BSD-style) — http://elm-chan.org/fsw/ff/
ESP-IDF glue: Copyright (c) Espressif Systems — Apache License 2.0
Copied unchanged from ESP-IDF v4.4.7 components/fatfs, except FF_FS_EXFAT and

SensorLib (T-LoRa Pager XL9555/BQ27220/AW9364/DRV2605/BHI260AP drivers)
Copyright (c) Lewis He — MIT License — https://github.com/lewisxhe/SensorLib
It bundles Bosch Sensortec's BHY2 SensorAPI (Copyright (c) 2023 Bosch
Sensortec GmbH, BSD-3-Clause) and the Bosch BHI260AP "Klio" firmware image
as distributed with SensorLib, which wadamesh uploads to the Pager's sensor
hub at first use.

ES8311 register sequence and clock-divider coefficients (T-LoRa Pager audio
codec driver, variants/lilygo_tlora_pager/Es8311Codec.cpp; T-Display P4 audio
driver, variants/tdisplay_p4/P4Audio.cpp)
Copyright (c) 2023-2026 Espressif Systems (Shanghai) CO LTD
Apache License 2.0 — https://github.com/espressif/esp-adf-libs and
https://github.com/espressif/esp-bsp (components/es8311)
wadamesh's drivers are original code (not copies of esp_codec_dev's
plugin/HAL architecture) but their ES8311 register addresses, startup/
power sequences, and MCLK clock-divider coefficients are derived from
Espressif's public es8311.c/es8311_reg.h; P4Audio.cpp additionally
re-bases the esp-bsp init flow onto Arduino Wire.
ST7701S panel init list (SenseCAP Indicator display driver,
variants/sensecap_indicator/IndicatorDisplay.cpp)
Copyright (c) Meshtastic
GPL-3.0 License — https://github.com/meshtastic/device-ui
The panel's second init command list (MADCTL vertical flip, SDIR
horizontal flip) is taken from Meshtastic device-ui's
include/graphics/LGFX/LGFX_INDICATOR.h (Panel_Indicator::getInitCommands).
The rest of the driver is original code on LovyanGFX's Panel_ST7701.

Camillia-MT (CrowPanel Advance 3.5 software-SPI microSD backend)
Copyright (c) 2025-2026 Michael A. Cojocari and contributors
GNU General Public License v3.0 or later
Adapted from src/sd_soft_spi.cpp; integrated with WadaMesh's filesystem
API and concurrent storage consumers.
Camillia-MT (CrowPanel Advance 5.0 display, backlight and touch bring-up)
Copyright (c) 2025-2026 Michael A. Cojocari and contributors
GNU General Public License v3.0 or later
The RGB panel configuration, revision detection, backlight controller and
GT911 reset in variants/crowpanel_50/CrowPanel50Display.cpp are adapted
from src/hal/crowpanel_50_display.h and src/hal/hw_crowpanel_50.h.
LilyGo cpp_bus_driver (T-Display P4 vibration motor, AW86224 haptic driver,
variants/tdisplay_p4/P4Haptic.cpp and P4HapticWaveform.h)
Copyright (c) LILYGO
GPL-3.0 License (version 3 only; no "or later" grant) —
https://github.com/Llgok/cpp_bus_driver
The AW86224 register sequence (RAM-mode init, waveform load/verify,
playback, stop) is adapted from src/chip/i2c/aw862xx.cpp and re-based onto
Arduino Wire; the "12k_041230_235" RAM waveform library is copied verbatim
from src/chip/i2c/aw862xx_haptic_waveform_table.inc. Those two files keep
upstream's terms (SPDX GPL-3.0-only).
This list is not exhaustive and is expanded as dependencies are vendored or
added.
