Frequently asked questions
How do I set the logic voltage for a 3.3V board?
Supply the VCCIO pin at the level your target board uses, as described in the datasheet. Mismatched logic levels can damage the inputs of the target device.
Does it need a driver on Windows?
Windows usually installs FTDI's VCP driver automatically, which presents the chip as a COM port. If it does not, install the driver from FTDI.
