Overview
Wee is a WIFI module based on ESP8266 SoC. ESP8266 comes out of nowhere and has been taking by storm the IoT world. You can find many hacking projects about it on the internet. So far, the most popular ESP8266 breakout version only has GPIO0 and GPIO2 routed to the header. Compared to it, Wee WIFI module is designed with a standard Bee interface and has more GPIOs available for developers. In a word, users can take full use of the utility of ESP8266 SoC by using Wee WIFI module in your projects.

How to upgrade ESP8266 firmware?
We use NodeMCU flasher here, the download links:
- English version: https://github.com/nodemcu/nodemcu-flasher
- Chinese version: File:ESP8266Flasher-x86-v0.9.2.3.zip
In this instruction, we will demonstrate the firmware upgrading by using Wee and Foca Pro.
- Plug the Wee in Foca Pro, then make sure that the switch level is 3.3 V in Foca Pro and the Wee is in FW mode.
English Version: Please refer to the NodeMCU flasher user guide.
Chinese Version: Please see the guide below
- Open the software, choose the right COM and click the button that is circled in the following picture. When a tick appears in the bottom-left corner, it suggests that the firmware upgrade successfully.
- This software contains an existing firmware, but if you want to flash other ESP8266 firmware, please click the button that is circled in the following picture, and only two file path are available to choose.
