E103-W10 ESP8285N08 Serial UART to WIFI Module 2.4GHz WI-FI Converter Module Wireless Support TCP/IP HTTP MQTT AT Command




[WiFi version]:802.11b/g/n


[Product weight]:0.9g±0.1g

[Introduction]:E103-W10 is an ultra-cost-effective 100mW serial-to-Wi-Fi module with a small package of patches that work in the 2.4 to 2.4835GHz band. The module can use serial port for data sending and receiving, reducing the threshold for wireless applications.
