The overall length of the micro base to type c male head is 26mm, which is one of the many types of OTG. One end of the product is a riveted type c male head, and the other end is a micro base. OTG is an abbreviation for On The Go, which was announced by the USB Standardization Organization on December 18, 2001. It is mainly used for connecting different devices or mobile devices for data exchange. Due to the development of USB technology, it is possible for PCs and peripheral devices to connect various devices in series for data transmission in a simple and low-cost manner. However, this convenience and simplicity are limited to the PC end, and once left, it cannot be carried out. This makes it difficult for many people to meet their needs, especially in the era of smart computers that began in 2012. So various manufacturers integrated the OTG technology announced by the USB Standardization Organization on December 18, 2001, allowing it to connect to various devices at any time for data exchange and transmission. To this day, OTG functionality is already standard on smartphones. However, some mobile phones cannot be used directly, and this feature needs to be enabled in the device. For example, with the OTG function, the USB keyboard and mouse will no longer be dedicated peripherals for computers, but can also be used on mobile phones. Through the OTG cable, one end is connected to the phone, and the other end is inserted into the USB mouse or USB keyboard. The mouse and keyboard will be connected to the phone and can be used. The phone can be accessed through OTG, with one end plugged into the phone interface and the other end plugged into a USB drive, allowing the phone to read data from the USB drive. Connect various peripherals, and the phone can directly output HDMI data to the external large screen through an OTG to HDMI cable. A phone with OTG function can be turned into a mobile power source to charge other phones.
