FAQ
How to configure modules?
Use EBYTE's EWM181_Zigbee_Setting_V1.0 software (Windows) via USB-UART converter.
Can Z20SP use external antennas?
No. Z20SP has fixed PCB antenna. For external antennas, choose Z20SX version.
Maximum network size?
Supports 100+ nodes in mesh topology with routers extending coverage.
