01 / Energy and protection
D5 solar panel enclosure
A 5 W solar panel, enclosure, and charging controller form the framework for your outdoor node. The adjustable bracket makes it possible to point the panel towards the sun.
The enclosure is designed for Heltec V3, Heltec V4, and Mesh Node T114. Batteries are sold separately.

Heltec WiFi LoRa 32 V4
The ESP32-S3R2 and SX1262 combine WiFi, Bluetooth LE, and LoRa on a single board. The OLED display provides status updates directly on the node.
16 MB of flash and 2 MB of PSRAM provide space for firmware and your own projects. Use the firmware for the correct V4 revision and select EU_868 in Meshtastic.

L76K GNSS + cable
For Heltec V4: Connect the separate L76K module using the included 8-pin cable.
Add satellite positioning with the L76K, which supports GPS, GLONASS, BeiDou, and QZSS. Position the antenna with a clear view of the sky.
The 8-pin cable is included with the V4. The V3 requires manual configuration of the UART, power supply, and firmware; additional wiring or adapters are not included.
8-pin cable included · Up to 10 Hz · 2.5 m CEP under test conditions

WisMesh 868 MHz antenna
A high-performance blade antenna for 863–870 MHz. The included adapter connects the antenna's RP-SMA connector to standard SMA.
The kit's pigtail allows the antenna connection to be routed from the board to a panel mount. The antenna is an alternative to the other included LoRa antennas; install one suitable antenna per radio connection.
50 Ω · Max. 2.8 dBi · RP-SMA to SMA adapter included

SMA ↔ U.FL pigtail
The 10 cm coaxial cable carries the LoRa signal from the board's U.FL/MHF1 connector to an SMA female connector on the enclosure.
The passive 50 Ω connection is suitable for 868 MHz projects. Snap the PCB connector into place, avoid sharp bends, and seal any new enclosure entry point.
10 cm · SMA female to MHF1/U.FL female · 1.13 mm coaxial cable

RASMINE’S WORKSHOP
From loose parts to your first connection.
Start on the workbench, then move outdoors. This is a DIY project that needs assembly and configuration.
- Mount the selected board in the D5 enclosure. Check battery, voltage, connectors and polarity.
- Install firmware for the selected board and correct revision, then select the EU_868 region.
- Connect a suitable antenna, test with a second node, then check power and coverage at the installation site.
Build your own solar-powered mesh node
Choose Heltec V3 or V4, with or without GNSS. The kit includes your chosen board, a 10 cm SMA/U.FL pigtail, a WisMesh 868 MHz blade antenna with adapter, and a D5 solar enclosure with a 5 W panel. The GNSS variant also includes an L76K module and an 8-pin cable.
A DIY kit for those who want to work with Meshtastic, LoRa, and location sharing. The components are supplied loose, so you choose the mounting, battery, and firmware yourself.
