One-click access to flash mode, no wiring required.

Uses standard pinout for full compatibility with Uno, Mega, and other boards (except for standard sizes like Nano and Mini).

Uses a high-end 3.3V power supply chip (the same as the one used in the official CC3000 expansion board) to ensure a more accurate 3.3V supply, allowing the ESP8266 to operate just like the official CC3000 chip, without any discrepancies.

A WiFi module power/repair port is included for easy power expansion and maintenance.

The board includes an ESP8266-12 industrial-grade, stable serial port WiFi module with an enhanced PCB antenna for superior signal quality.
The ESP8266-12 industrial-grade stable WiFi module’s operating mode (such as run mode and upgrade mode) can be quickly switched using a DIP switch. The integrated serial port chip allows for fast firmware flashing.

A built-in 5V to 3.3V TTL level converter prevents damage to the WiFi module caused by high-voltage TTL voltages. (This is not available on standard modules.)

The onboard ESP8266-12 industrial-grade stable WiFi module features a metal shield for strong interference resistance.

All interfaces of the onboard ESP8266-12 industrial-grade stable WiFi module are connected with standard spacing, facilitating in-depth development.

24/7 online technical guidance, sample programs, and technical documentation are available through the QQ group, forum, and email.

The stackable design allows for the addition of additional modules for easy use.

Four onboard LEDs indicate the ESP8266 status: PWR, DFU, AP, and STA, and the operating mode is displayed at a glance.
