Product Description
- Supporting Lua program, easily to develop.
- Supporting three modes: AP, STA, and AP+STA.
- Small volume, easily embeded to other products.
- Strong function with support LWIP protocol, Freertos.
- High performance-price ratio.
When you do some ESP32 projects you must hate to add a power bank to provide the power. This tiny board could solve such problems. A LG 3000mAH 18650 battery could make ESP32 run 17 hours or more.

The « LJ12A3-4-Z/BX » is an inductive proximity sensor that detects metal objects within a 4mm range. It operates on a DC 6-36V power supply and has an NPN (Normally Open) digital output, meaning it completes a circuit to the signal line when it detects metal. These sensors are used in industrial automation for non-contact switching, control, and detection
The MQ2 analog gas sensor is used in gas leak detection equipment. This sensor is suitable for detecting LPG, butane, propane, methane, alcohol, hydrogen, and smoke. It has high sensitivity and a fast response time; the sensitivity can be adjusted using a potentiometer.
The SG90 servo motor is a type of continuous rotation motor controlled by a digital signal. It is used in projects such as robotics, position control systems, and DIY projects.
