Meshtastic adds Heltec Tower v2 board support

A new Heltec Tower v2 board definition is exactly the kind of unglamorous firmware work that saves a build later. Meshtastic opened pull request #10705, “Add Heltec tower v2 board,” on June 16, and the payoff is straightforward: if the board lands cleanly, the firmware, flasher, and docs can recognize it instead of treating it like a mystery variant.

That matters in a hardware ecosystem where the details are everything. Meshtastic already supports a wide spread of boards across several Heltec families, and the Tower v2 entry suggests the project is still actively tightening its supported-device tree as vendors keep shipping new versions. For a builder, official board support usually means correct pin assignments, better defaults, a cleaner flashing path, and fewer awkward sessions spent hunting through forum posts and hand-editing configs.

The move also lands against some old Heltec baggage. In earlier discussion, Meshtastic maintainers said the older Heltec v2 had “a ton of battery issues” and that the chip could crash and behave erratically. Another January 2024 thread noted that board was not in the web flasher, even though firmware files were still present in the bundle, and that direct flashing with esptool.py could work, quirks and all. That history makes the Tower v2 addition feel more deliberate than cosmetic: Meshtastic is not just lumping every Heltec board together, it is deciding which ones deserve clean support on their own merits.

Heltec is also pushing MeshTower V2 as a Meshtastic-ready product line. Its quick-start material says the series comes in two versions, a standard-power model rated at 21 ±1 dBm and a V2H version rated at 28 ±1 dBm. Heltec says both use the same setup and operating steps, ship with Meshtastic firmware preinstalled, and use 123456 as the default password. The board also supports 18-24V solar input, DC 18-24V input, and USB-C PD3.0 at 20V, while Heltec describes the enclosure as an IP66-rated metal outdoor unit built around solar-powered communication.

Meshtastic’s own hardware guidance helps explain why this sort of board support matters. The project says newer Semtech SX126x or LR11xx radios are preferred, and that nRF52 devices are generally lower power than ESP32-based devices. In practice, that means the Tower v2 entry is not just another name in a long list. It is part of the line between a board that feels officially alive in the Meshtastic world and one that still makes you do the last 20 percent by hand.
