  "textContent": "DFRobot’s RainbowLink-V2 USB-to-serial converter features four independent channels, namely one isolated RS-485, one isolated RS-232, and two TTL interfaces usable simultaneously. The compact tool also converts 5V provided from the host’s USB interface to 12V/800mA, 5V/2A, and 3.3V/200mA outputs, eliminating the need for a separate power adapter. RainbowLink-V2 (TEL0190) specifications: USB – 1x USB Type-C port for power and adata Serial 2x TTL (3.3V) via headers 1x fully isolated RS485 channel via lever terminal 1x fully isolated RS232 channel via lever terminal Baud Rate – 2400 to 128000 bps Misc 3x Power LEDs for 3.3V, 5V, and 12V 4x Link LEDs for TTL 1/2, RS232, and RS485 12AWG – 22AWG wires supported on lever-type spring terminals Built-in short-circuit protection and overcurrent protection (but users are still recommended to avoid short-circuiting to prevent damage) Input voltage – 5V via USB-C port Output voltage 3.3V up to 200mA via header 5V up [...]\n\nThe post RainbowLink-V2 compact USB-to-serial converter features 12V output, dual TTL, isolated RS-485 and RS-232 interfaces appeared first on CNX Software - Embedded Systems News.",
