The module converts the USB voltage into four independent TTL channels, each operating at 3.3 V, without requiring an additional power supply.\u003c\/p\u003e \u003cp\u003eEach channel operates independently of the others, so faults on one connection do not affect the remaining channels. Galvanic isolation protects the host system from voltage spikes flowing back into it. This allows several modules with different baud rates and protocols to be operated in parallel, for example to troubleshoot multiple sensors simultaneously or read debug output from various microcontroller boards.\u003c\/p\u003e \u003cp\u003eTypical scenarios include the serial diagnosis of multiple devices in a prototype setup, parallel data collection from different measuring stations, or operating several wireless and communication modules on a single computer. The adapter also provides a reliable connection as a development tool for embedded systems that operate without a graphical interface.\u003c\/p\u003e \u003cp\u003eThe adapter requires a USB port with an operating system capable of emulating a serial COM port. On the target system, the corresponding interfaces of the Raspberry Pi Zero, such as UART pins, must be available. If the current consumption exceeds 500 mA per channel or connections to high-frequency modules are unstable, a separate power supply for the target devices may be necessary.\u003c\/p\u003e \u003ch3\u003eSafety Information\u003c\/h3\u003e \u003cp\u003eThe adapter is intended exclusively for prototyping, testing, and development purposes and must not be connected to the household power circuit. The connections operate with logic-level voltages; connections to devices with higher voltages require level shifters, otherwise damage may occur. Work on or near electrical installations is reserved for qualified electricians; if you are unsure about commissioning the device, consult a qualified electrician.\u003c\/p\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66042932724061,"sku":"F23108468","price":15.65,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/4566-F23108468_01.png?v=1791482828","url":"https:\/\/funduino.com\/en\/products\/usb-to-ttl-hub-adapter-for-raspberry-pi-zero","provider":"Funduino","version":"1.0","type":"link"}
