Meshsolar Development Board NRF52840+SX1262 LiFePO₄ Version Core Board Support Bluetooth Low Power Consumption LoRa Wireless Communication for Solar Power Supply System/Remote Monitoring/Meshtastic

MeshSolar is an integrated power management and communication solution development board designed for outdoor low-power devices, consisting of a BMS power management board and a BLE + LoRa communication control main board. The development board features solar MPPT charging, multi-protocol fast charging (supports USB PD3.0 and 18-24V DC input)

Professional battery management: supports 1-4 battery configurations; achieves balanced charging for optimal battery performance; has comprehensive protection functions, including overcharge/overdischarge/short circuit/overtemperature protection measures

Multi-mode charging: 18-25V solar MPPT charging; USBPD3.0 fast charging; 18-25V external DC charging

Connectivity and expansion: Bluetooth connectivity + LoRa telematics (up to 21 + 1dBmTX power, 10km range) dual-mode wireless communication; M.2 MCU interface; supports display, GPS, and general-purpose I/O expansion

With its low-power design, extensive hardware expansion interfaces (supporting displays, GPS, and general-purpose I/O), and seamless compatibility with HT-n5262M modules (nRF52480 + SX1262), MeshSolar is well-suited for high-power or long-term stable power applications such as solar systems and remote monitoring. It also fully supports the Meshtastic ecosystem.
