{{page>en:hw:004-edge:edge-in-development-hidden}} ====== Peripherals ====== #;; Edge #;; Unipi Edge has a number of peripherals, most of which are optional. These include serial ports, USB, Ethernet, Wi-Fi, LTE, HDMI, GNSS, RTC, TPM, NVRAM, etc. Serial ports (RS-485):\\ RS-485 is a serial bus standard for data transfer between devices in industrial and automation applications. Twisted-pair cables are used to connect the devices and the most common communication protocol is Modbus RTU. Port mapping and technical information about RS-485 can be found [[.:06-peripherals:01-rs485|here]]. ---- /* USB optional:\\ */ USB (optional):\\ USB is an industry-standard serial bus designed for connection and communication between devices using a master/slave system. Devices such as keyboard, USB storage and similar can be connected to the controller. It can also power the connected devices. Port mapping and technical information about USB A ports can be found [[.:06-peripherals:02-usb|here]]. ---- LTE (optional):\\ LTE is wireless communication technology designed for data transfer in GSM networks. Devices equipped with LTE can send text messages, make calls, and access the internet via LTE data. Port mapping and technical information about LTE and GNSS can be found [[.:06-peripherals:03-lte|here]]. ---- WLAN (optional):\\ Wi-Fi is a set of wireless communication protocols that are based on the IEEE 802.11 standards. Devices equipped with a Wi-Fi module can connect to or act as, a local access point (AP). Port mapping and technical information about Wireless LAN (Wi-Fi & Bluetooth) can be found [[.:06-peripherals:04-wlan|here]]. ---- /* M-Bus (optional):\\ M-Bus (Meter-Bus) is a communication bus and protocol designed primarily for remote meter reading, such as electricity meters, water meters, gas meters, or heat meters. It allows multiple devices to be connected to a single line, enabling centralized reading and reliable transmission of measured data even over long distances with minimal cabling and power requirements. Port mapping and technical information about M-Bus can be found [[.:06-peripherals:05-mbus|here]]. ---- */ Other:\\ More information about TPM, Retain and other peripherals for Unipi Edge can be found [[.:06-peripherals:09-other|here]].
