Any 18650 lithium battery with a voltage range of 3.3~4.2V.
No, it does not feature waterproofing.
When the device is identifying GPS, the timing of the buzzer is disrupted, causing it to sound somewhat unusual. This commonly occurs when the device is first started up, and it will return to normal after about one minute.
Starting from version 2.7.14 or newer, the firmware for the touchscreen version has been merged. If you are unsure how to install it, you can click this link and follow the guide provided to install the firmware.

WiFi LoRa 32 Expansion Kit
What's this?
The WiFi LoRa 32 V4 Expansion Kit already includes V4 and pre-installed accessories. You can also customize your own hardware via the MQB platform.
- Note: Selecting the battery option will significantly increase shipping costs.
Price range: $49.90 through $58.90
Info –
The LoRa 32 inside is based on ESP32; you can update the firmware simply by plugging it in, without needing to enter DFU mode. This document may make sense to you.

Please tell me how to enter DFU mode! How do I reflash this device now?

General Overview:
-The WiFi LoRa 32 (V4) delivers transmit power up to 28 ± 1 dBm.
-According to Heltec’s published testing, the V4 offers improved receiver sensitivity compared to earlier models.
-Includes expanded memory, featuring 2 MB PSRAM and 16 MB external Flash.
-Supports Wi-Fi (802.11 b/g/n), Bluetooth LE / BT5 / Mesh, and LoRa connectivity.
-Offers a solar input port.
-Features a plug-and-play GNSS (GPS) interface on the underside of the board.
-Meshtastic firmware v2.7.13 provides full compatibility, and VNA testing has confirmed the board achieves its advertised transmit power using this firmware or greater.
When I purchased the WiFi LoRa 32 (V4) it was my first Heltec device after previously using LilyGO hardware. I was pleasantly surprised by the overall build quality. It’s clear that Heltec put some thought into the design, especially its compatibility with their optional WiFi LoRa 32 Expansion Kit.
I currently own two V4 units: one serves as a home base station connected to a rooftop antenna, and the second will likely become a portable node I carry with me. I’m also possibly considering using one in a solar-powered weather station project next summer. I would have to say this is a must have for beginners. Well there is always room from improvement like using a next generation radio, it checks most of the boxes meshtastic users currently require.
My experience buying directly from Heltec wasn’t perfect there were shipping delays during the initial launch week but customer service was responsive and the devices did arrive. For anyone ordering during high-demand periods like a devices day one launch, I’d keep in mind you should expect delays, or use third-party resellers like AliExpress or Amazon for potentially faster delivery.
Common User-Reported Issues:
-Some users would have preferred Heltec reversed the Battery and Solar connectors for better case compatibility; however this is a personal preference and as it stands does not affect device functionality.
-Due to GPIO layout changes relative to the previous WiFi LoRa 32 (V3), not all third-party accessories are backward compatible.
-Many V3 enclosures are not compatible with the V4 because of dimensional changes particularly because of the addition added OLED faceplate.
