WIFI-10 module for DWIN Cloud Development Platform ESP8266 + 4MB flash 2.4-2.5G Adapter

WIFI-10 module for DWIN Cloud Development Platform ESP8266 + 4MB flash 2.4-2.5G Adapter

The V2.0 hardware package definition is shown in the figure above, and the pin pitch is 2.0mm.

the difference:
IO14/SCL: I2C interface SCL, WIFI module output
DL/SDA: WIFI module download enable, internal pull-up resistor 10K. When the module is powered on, this pin is low, which means it enters the boot mode. Just use the suspension normally.
For the SDA of the I2C interface, if the I2C interface is enabled, the TX function of UART1 needs to be disabled.

1.Characteristic parameters
Main chip ESP8266+4MB Flash
Support 802.11 (2.4 GHz), frequency range 2.4G ~ 2.5G (2400M ~ 2483.5M)
PCB onboard antenna
Maximum transmit power 14dBm
Serial port transmission rate 921600bps (device-side transmission data rate)

2. Hardware interface
The V1.0 hardware package definition is shown in the figure above, and the pin pitch is 2.0mm.
The WIFI module should have 7 pins in total, VCC (3.3V), GND, TXD, RXD, C/D, TXD_C, and /RST.
TXD, RXD: data channel, baud rate 921600.
TXD_C: It has nothing to do with the business, the internal information printout pin, which is left floating.
C/D: WIFI module download enable, internal pull-up resistor 10K. When the module is powered on, this pin is low, which means it enters the boot mode. Normal use can be suspended
3V3, GND: Need to ensure a peak current of 300mA.
/RST: Reset pin, need to connect the reset chip to reset reliably. Low level resets the WIFI module.

WIFI-10 module for DWIN Cloud Development Platform ESP8266 Overview

The WIFI-10 module is a dedicated wireless adapter designed for seamless integration with the DWIN Cloud Development Platform. Based on the ESP8266 chip and offering 4 MB of onboard flash, it provides reliable 2.4 GHz Wi-Fi connectivity directly to your HMI or embedded project.

Key Features of WIFI-10 module for DWIN Cloud Development Platform ESP8266

• Main chip ESP8266 with 4 MB flash for robust firmware storage
• Supports IEEE 802.11 b/g/n in the 2.4 GHz band (2400–2483.5 MHz)
• PCB onboard antenna delivering up to 14 dBm maximum transmit power
• High-speed serial interface at 921600 bps for fast data transfer
• V2.0 hardware layout with 2.0 mm pin pitch for easy mounting
• Genuine product, fast shipping from Zbotic within 24 hours*

Applications and Use Cases

• Adding Wi-Fi connectivity to DWIN HMI displays and control panels
• Uploading sensor data to the DWIN Cloud for remote monitoring
• Implementing wireless firmware updates over a local network
• Building smart home interfaces with real-time status dashboards
• Prototyping IoT devices that require reliable 2.4 GHz communication

How to Use WIFI-10 module for DWIN Cloud Development Platform ESP8266

Simply solder the WIFI-10 module onto the 2.0 mm header footprint of your DWIN developer board, supply 3.3 V power, and connect the serial port at 921600 bps. To enter the internal bootloader, pull the DL/SDA pin low on power-up. If you enable the I2C interface (IO14 as SCL), remember to disable UART1 TX on that pin before use.

Frequently Asked Questions

How do I enter the bootloader mode on the WIFI-10 module?

Hold the DL/SDA pin low (internal pull-up 10 KΩ) when powering on the module. This forces ESP8266 into boot mode for firmware flashing.

Which pin provides the I2C SCL function?

IO14 doubles as the I2C SCL interface output. If you enable I2C, disable the UART1 TX function on IO14 to avoid conflicts.

What serial speed should I use for communication?

Set your host UART to 921600 bps to match the module’s maximum serial port transmission rate for optimal performance.
