The tables below are built from the repo's PlatformIO board metadata and variant build flags.

- `Target` is the short board name used in this comparison page. Release filenames and local build commands still use the full env names such as `heltec_v4_repeater_mqtt`.

- `MCU` shows the chip family only. Actual runtime clock can vary by env and board configuration.
|

- `RAM` is the MCU's built-in RAM.

- `PSRAM` is extra memory on some boards. More PSRAM usually means more headroom for UI, MQTT, and future features.
