ZBT 4G LTE Router | 300Mbps WiFi | MT7628NN | Hardware Watchdog | Dual SIM - WE2805-A-KC

ZBT WE2805-A-KC — Industrial 4G LTE Router with Hardware WatchdogThe WE2805-A-KC is a reliable industrial-grade 4G LTE router built on the MT7628NN platform. Designed for mission-critical deployments, it features a built-in hardware watchdog that automatically recovers from system crashes — ensuring 24/7 uptime without manual intervention. With 2.4G WiFi 300Mbps and SMT LCC+LGA 4G module interface supporting 3G&4G, it’s the dependable backbone for IoT, retail, and enterprise connectivity.Key Features MT7628NN Chipset: MIPS24KEc architecture, up to 580MHz — proven stability for routing workloads 2.4G WiFi 300Mbps: IEEE 802.11 b/g/n with 2T2R MIMO, 20/40MHz bandwidth SMT LCC+LGA 4G Module: Supports 3G & 4G mobile communication; swappable modules for different regional frequency bands Hardware Watchdog: Auto-detects system crash every 1 second; restarts entire system within 15 seconds if heartbeat lost for 120 seconds 4G Module Power Control: Routing system independently controls each 4G module’s power; auto power-cycles failed modules 4× External Antennas: 2× 2.4G 5dBi + 2× 4G 5dBi omnidirectional removable antennas Hardware Specifications Component Specification Processor MT7628NN, MIPS24KEc, up to 580MHz 2.4G WiFi Chip MT7628NN integrated, up to 300Mbps RAM DDR2 64MB Flash NOR Flash 8MB (NAND Flash not supported) 4G Module Interface SMT LCC+LGA, supports 3G & 4G Antenna 2× 2.4G 5dBi + 2× 4G 5dBi external removable omnidirectional LED Indicator Status LED State Meaning Red constant Powering on / system running Green constant WiFi normal Green flashing WiFi started, data communication active Blue constant 4G dialing successful Blue flashing 4G dialing successful, data communication active Green flashing (combined) WiFi started + 4G dialing successful + data communication active WiFi Wireless Parameters Standards: IEEE 802.11 b/g/n; supports IEEE 802.11 d/h/k Bandwidth: 20MHz / 40MHz MIMO: 2T2R Max Rate: 300Mbps Working Frequency: 2412–2484 MHz Transmit Power (11Mbps CCK): 17–19 dBm | (54Mbps OFDM): 15–17 dBm Reception Sensitivity (11Mbps CCK): -89 to -86 dBm | (54Mbps OFDM): -76 to -72 dBm Hardware WatchdogThe hardware watchdog activates automatically on power-on and monitors the routing system heartbeat every 1 second. If no heartbeat is detected within 120 seconds (e.g., system crash), it shuts down and restarts the entire system within 15 seconds. The routing system also independently controls each 4G module’s power supply — automatically power-cycling any module that fails to dial.Power Supply Parameter Min Rated Max Unit Working Voltage 6 12 14 V Absolute Working Voltage 5.5 — 16 V Working Current (VIN=12V) 0.4 0.6 1 A ⚠️ Use the ZBT standard 12V/1A power adapter.
