The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm.
An on-board LED will give a visual indication of when the sensor is triggered. When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output. TTP223 Capacitive Touch Sensor Module. The TTP223 is a touchpad detector IC replicating a single tactile button. The TTP223 is a touchpad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button key with diverse pad size.
- Trigger-setting mode: (1 -> Short; 0 -> No Short)
- AB=00: No-lock High TTL level output;
- AB=01: Self-lock High TTL level output;
- AB=10: No-lock Low TTL level output;
- AB=11: Self-lock Low TTL level output;

Ordering the PCBs From JLCPCB
Full Process is shown using Screenshots Step-wise.
Now we have got the PCB design and it’s time to order the PCB’s. For that, you just have to go to JLCPCB, and click on “QUOTE NOW” button.
JLCPCB are also sponsor of this project. JLCPCB (ShenzhenJLC Electronics Co., Ltd.), is the largest PCB prototype enterprise in China and a high-tech manufacturer specializing in quick PCB prototype and small-batch PCB production. You can order a minimum of 5 PCBs for just $2.
To get the PCB manufactured, upload the gerber file you downloaded in the last step. Upload the.zip file or you can also drag and drop the gerber files.
After uploading the zip file, you’ll see a success message at the bottom if the file is successfully uploaded.
You can review the PCB in the Gerber viewer to make sure everything is good. You can view both top and bottom of the PCB. After making sure our PCB looks good, we can now place the order at a reasonable price. You can order 5 PCBs for just $2 but if it’s your first order then you can get 5 PCBs for $2.
To place the order, click on “SAVE TO CART” button. My PCBs took 2 days to get manufactured and arrived within a week using DHL delivery option. PCBs were well packed and the quality was really good.
