How does the high current charge Pogo pin apply to PDA?
PDA (Personal Digital Assistant) means personal digital assistant. As the name suggests, it is a digital tool to assist individuals in their work, mainly providing functions such as notes, address book, business card exchange, and itinerary arrangement.
The biggest feature of the handheld computer is that it has an open operating system, supports software and hardware upgrades, integrates information input, storage, management, and transmission, and has powerful functions such as commonly used office, entertainment, and mobile communications. Therefore, the PDA can be called a mobile office.
Of course, not all PDAs have all the above functions; even if they do, they may not be implemented due to a lack of corresponding services. But it is foreseeable that the trend and trend of PDA development is the integration of computing, communication, network, storage, entertainment, e-commerce, and other functions.
