A sample connection set-up is shown below. They also require a pull-down resistor of value 15K each for the data to transfer. These pins should be connected to the D+ and D- pins of the host respectively. The remaining two pins are the D+ and the D. The ground pin is connected to the ground of microcontroller. The supply voltage of Vcc is +5V and is usually provided from the Microcontroller itself. Of the remaining four pins two pins (pin 1 and Pin 5) are used to provide the Vcc and Ground. The micro USB Jack has five pins through which the power and data is transferred, the 4th pin ID is used for mode detection, this indicates if the USB is used only for power or for data transfer. Click to list> The micro-USB connector is often used for portable devices charging (with micro-usb charging cable ) or mobile devices data transfer (with micro-usb data cable ). However it is recommended not use loads more than 500mA for USB connectors as per USB consortium. Micro-USB is a standard connector for a wide range of portable devices, including cell phones and smartphones The pinout should fit 74 devices/models. The maximum current that can be handled by this connector is 1A. The micro USB connector can be used to power or communicate with devices. Moxas UPort series USB-to-serial converters provide computers with high-performance, industrial-grade connections for up to 16 serial devices over a single. Two new OTG cables are defined, the mini-A to B, and the mini-A to mini-B (see Figure 4). So if you are looking for an USB option on your project which occupies less space, this might be the right choice for you. As its name implies, the mini-AB receptacle accepts either the standard mini-B plug, or a new OTG plug, the mini-A. This data communication can receive data from any other MCU/MPU or even a computer or mobile phone. These sockets have 5 pins, out which is two is used for power supply and other two is used for data communication. Similarly it is used for the same purpose on raspberry pi, ESP modules and much more. It can be commonly found on Mobiles phones as charging/communication ports. ![]() The micro USB jack finds its applications in many embedded projects where serial communication or power supply is required. Available as standard, drop in and reverse mount.
