Product introduction
What’s this?
MeshSolar integrates a BMS board and an BLE+LoRa communication control mainboard, supporting solar charging while perfect compatibility with Meshtastic. Warning: Verify the battery switch alignment with solder points and battery connected before applying power (activation/charging/setup) to avoid board damage. MeshSolar requires a 20V charger for activation. If a 20V charger is not available, a compatible 20V power adapter can be purchased separately.
Note Verify the battery switch alignment with the solder points and ensure the battery is connected before applying power (activation/charging/setup) to avoid board damage.
MeshSolar is an integrated power management and communication solution designed for outdoor low-power devices, consisting of a BMS Power Management Board and an BLE+LoRa Communication Control Mainboard. The system features solar MPPT charging, multi-protocol fast charging (supporting USB PD3.0 and 18–24V DC input), intelligent battery management (compatible with 1–4 cells/battery packs, with overcharge/over-discharge/short-circuit/over-temperature protection and balanced charging), and dual-mode Bluetooth + LoRa wireless communication (LoRa range up to 10 km with 21±1 dBm transmit power).
With its low-power design, extensive hardware expansion interfaces (supporting displays, GPS, and general-purpose I/O), and seamless compatibility with the HT-n5262M module (nRF52480 + SX1262), MeshSolar is ideal for high-power or long-term stable power supply applications such as solar-powered systems and remote monitoring. It also fully supports the Meshtastic ecosystem.
