EBYTE E18-MS1-PCB

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 E18 series modules adopt the CC2530 RF chip, which integrates an 8051 MCU and a wireless transceiver. Select model variants include a built-in PA power amplifier for extended communication range. The factory firmware implements transparent serial data transmission based on the ZigBee 3.0 protocol and supports various commands under ZigBee 3.0. Verified through practical testing, it demonstrates excellent compatibility with most ZigBee 3.0 products on the market.

• Role Switching: Users can switch the device between Coordinator, Router, and End Device via serial commands.
• Auto Network Formation: 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 network node is lost, other nodes automatically join or maintain the original network (isolated nodes automatically rejoin the original network; non-isolated nodes maintain the original network). If the Coordinator is lost and non-isolated nodes remain in the network, the Coordinator can restore the original network. A rejoining Coordinator or a new Coordinator with the same user-configured PAN_ID will rejoin 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 2.5μA; users can receive pending messages within the configured wake window.
• Data Retention Time Setting: When the device operates as a Coordinator or Router, users can configure the data retention duration to work in conjunction with sleeping End Devices — storing data destined for End Devices and delivering it once the End Device wakes from sleep. A maximum of 4 messages can be stored; if exceeded, the oldest message is automatically cleared. Once the data retention period expires, the entire data buffer is automatically cleared.
