Hello, You should set handshake after setting property RtsEnable = true. Use properties as below:- _serialPort.RtsEnable = true; _serialPort.Handshake = System.IO.Ports.Handshake.RequestToSend; _serialPort.RtsEnable = false; Thank You

Hello, Right, existing LED drivers all have PWM engines. It depends on the LED, some have Vf = 1.8, and some have 3.5V. So, 15x3.5 = 52.5 V in direct mode. Also current, 20 mA or more? For low current low voltage OPA may be an option, or OPA buffered by transistor for high CV. Thank You
