[Introduction]:The E103-W12 series is an ultra-low power WiFi module developed by Chengdu Ebyte Electronics Co., Ltd. based on the Dialog DA16200 SoC chip that supports IEEE 802.11b/g/n. It has a built-in high-performance ARM Cortex-M4 processor and works at 2.4~2.4835 GHz frequency band, the maximum wireless transmission power can reach 20dBm. The module supports IEEE802.11 b/g/n standard. The module supports AP and STA modes, supports multiple network transmission protocols such as TCP/UDP/HTTP/MQTT, and can maintain WIFI connection in low power consumption mode.
