Board Comparison
The tables below are built from the repo's PlatformIO board metadata and variant build flags. RAM is the MCU's on-chip RAM where it is known from the MCU family. PSRAM is only shown when the repo declares it explicitly or enables it in board metadata. If the board enables PSRAM but the repo does not declare a size, it is marked as Yes (size not declared).
Quick Guidance
- Pick an
ESP32-S3board with16MBflash and PSRAM if you want the most headroom for MQTT plus UI:heltec_v4_tft,heltec_v4,Station_G2,T_Beam_S3_Supreme_SX1262. - Pick a TFT board if this will be used as a human-facing companion or field node:
heltec_v4_tft,heltec_tracker_v2,LilyGo_TDeck,Heltec_T190. - Pick e-paper if you want a status screen with lower idle draw and less frequent refresh:
Heltec_E213,Heltec_E290,Heltec_Wireless_Paper,ThinkNode_M5. - Pick a headless board if this is mainly a fixed MQTT gateway and screen space is not useful:
Xiao_C3,RAK_3112,Tenstar_C3,Heltec_ct62,Generic_E22. - Pick a GPS-capable board if location-aware/mobile use matters: the T-Beam family,
heltec_tracker_v2,Heltec_v3,heltec_v4,Station_G2,ThinkNode_M5. - If you want the most conservative, older radio family choices, the
SX1276boards areLilyGo_TLora_V2_1_1_6,Tbeam_SX1276, andHeltec_v2.

Rows with a trailing _ in the env name are still included because they exist in variants/eastmesh_mqtt/platformio.ini, but they look more experimental than the main EastMesh targets listed in local-builds.md.
