EBYTE E18-2G4Z27SI

The E18 series is a 2.4GHz ZigBee protocol-to-serial wireless module. It comes pre-loaded with a self-organizing mesh network firmware, ready to use out of the box, and is suitable for a wide range of applications (especially smart home). The module features the CC2530 RF chip, which integrates an 8051 MCU and a wireless transceiver. Certain model variants include a built-in PA power amplifier to extend communication range. The factory firmware implements transparent serial data transmission based on the ZigBee 3.0 protocol and supports various commands under the ZigBee 3.0 protocol. Verified through testing, it offers excellent compatibility with most ZigBee 3.0 products.

• Role switching: Users can switch the device between three types — Coordinator, Router, and End Device — via serial commands.
• Auto networking: The Coordinator automatically forms a network upon power-up; End Devices and Routers automatically search for and join the network.
• Network self-healing: If an intermediate node is lost, other nodes automatically join or maintain the existing network; if the Coordinator is lost and there are non-isolated nodes in the original network, the Coordinator can restore the original network.
• Ultra-low power consumption: When the device operates as an End Device, it can be set to low-power mode, with sleep duration adjustable based on user-defined intervals. In low-power mode, standby current is less than 2.5uA; the device can receive pending messages within the user-configured time window.
• Data retention time setting: When the device operates as a Coordinator or Router, users can configure the data retention time to work in conjunction with sleeping End Devices — storing data for End Devices and delivering it once the End Device wakes from sleep. Up to 4 messages can be stored; if exceeded, the first message is automatically cleared. Once the retention period expires, the data buffer is automatically cleared.
