I want to add an FTDI chip to my project so it can be connected via USB, rather than a separate FDTI cable.So I copied the schematic from the FTDI basic, from Sparkfun, and pasted it into my new project. Since I won't be using 3.3 volts, can I delete C1?
+3.3V output from integrated LDO regulator. This pin should be decoupled to ground using a 100nF capacitor. The main use of this pin is to provide the internal +3.3V supply to the USB transceiver cell and the internal 1.5k? pull up resistor on USBDP.
I'm pretty sure I have the Rx & Tx connected wrong too.
