If you are used to develop the product , be sure to choose us, our advantages are as follows : 1 .Power consumption.OurWIFIParameter module is powered3.3VPowered by,70mA-200mAPower consumption is far below normal marketWIFIModule. 2 .Design enhancements .Adopt a new4Layer design , compared to previous2Plates , stability and anti-interference ability , better quality ! 3 .AP + STA Mode.AT + STACan coexist ,Meet most customer requirements. 4 .Various versions of software support.We offer our customers a variety of test software for free , such asPCClient software , Android software. 5 .Strong supply capacity.Never out of stock, long-term stability of bulk supply worries, long-term module1000Sets of inventory, less than2000Piece usually2Week delivery. 6 .Stable performance.OurWIFIModules have been listed a year , after a number of technical personnel improvements versions rapid iteration . Stable performance, stand the test of the market . 7 .Free and open .Full liberalizationSDK,apiComplete. You can achieve the aspirations of secondary development . 8 .FCC / CEAuthenticate.Module byFCC,CECertification,MACAddress has been burning inside the module , without the customer to pay for another . WIFIModule Quality Assurance: 1,ByCEAndFCCAuthenticateThis is the electronic products into the EU and the United States access to proven , is a sign of quality products . 2After high and low temperature testing,-20°-80°Industrial Operating ambient temperature range. 3, Each with a specialized test equipment products are rigorously tested .
- The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
- Jog type : the initial state is low , high touch , do not touch is low ( similar touch of a button feature )
- Module can be installed in such as surface plastic, glass of non-metallic materials
- In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons
- Low power consumption
- Power supply for 2 ~ 5.5V DC
- Can replace the traditional touch of a button
- Four M2 screws positioning holes for easy installation
Power supply voltage VCC
Output high VOH
Output low VOL
Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V)
Output pin pull-up current (@ VCC = 3V, VOH = 2.4V)
Response time (low power mode)
Response time (touch mode)
Touch Sensor Interface :(the last picture show)
-Control Interface : A total of three pins (GND, VCC, SIG), GND to ground , VCC is the power supply , SIG digital signal output pin ;
-Power Indicator : Green LED, power on the right that is shiny ;
-Touch area : Similar to a fingerprint icon inside the area , you can touch the trigger finger .
-Positioning holes : 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install , to achieve inter- module combination ;
