Explore PCB requirements for portable and connected products. Use application-specific guides to identify the interfaces, power constraints and assembly needs of your device.
A smart pen can combine motion or pressure sensing, optical tracking, memory, Bluetooth communication, buttons, charging and a small battery in a narrow enclosure. The PCB architecture must preserve low-noise sensor signals and RF performance while still allowing...
A portable signature pad places a display or digitizer, input sensing, USB or wireless communication and power management in a thin enclosure that is handled continuously by the user. The main PCB has to preserve low-noise sensing and mechanically accurate flex...
A digital writing tablet can combine a display controller, pen or touch digitizer, application processor, memory, wireless connectivity, battery charging and USB or other external I/O in a thin enclosure. The main PCB must maintain display and sensing interfaces while...
An electronic stylus has one of the most restrictive mechanical envelopes in portable electronics. A narrow PCB may need to accommodate sensing, wireless communication, charging, pressure or motion sensors and a small battery while fitting inside a cylindrical or...
Portable RFID readers combine RF transmission, digital processing, wireless connectivity, battery charging and user-interface electronics inside a mechanically constrained enclosure. The PCB has to maintain stable RF behavior while also supporting dense component...
Portable payment terminals combine contactless RF, card interfaces, secure processing, wireless communication, display or touch, battery charging and external connectors in a small enclosure. Reliable production requires configuration discipline because changes to...
A portable NFC reader is not only a digital controller board. Its performance depends on the electrical relationship between the NFC IC, matching network, loop antenna and the nearby battery, display, ferrite and enclosure materials. A production board therefore has...
A mobile data terminal can combine application processing, memory, cellular connectivity, Wi-Fi/Bluetooth, GNSS, display or touch, storage, USB and battery or vehicle-power interfaces. The main PCB must manage high-speed digital signals, RF modules and power...
A handheld POS terminal can combine a secure processor, display and touch interface, contact or contactless payment interfaces, Wi-Fi/Bluetooth or cellular communication, battery charging, audio and docking functions. Manufacturing quality depends on exact...
A handheld inventory terminal can combine barcode scanning, RFID, a display or touchscreen, keypad, Wi-Fi/Bluetooth or cellular communication, battery charging and docking contacts. The PCB therefore sits at the center of several mechanically and electrically...
