Based on esp-07s using lithium battery and using external antenna esp8266

Overview

1. Powered by 3.7V lithium battery.

2. Micro USB port for charging, two indicator lights, red light for charging and green light for full charge.

3. The switch controls the power supply of the esp-07s chip and plays the role of turning it on and off.

4. Using the 1st generation ipex antenna, you can choose an antenna with a higher dbi than other esp8266 modules with onboard antennas.

5. Small size and can be hidden.
