Perfect for connecting a mouse and maybe a modem. Nowadays, long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your everyday serial data from two serial ports to a single USB port without the complexity of a hub. What now? Enter the Adafruit CP2105 Friend!\u003c\/p\u003e \u003cp\u003eThe CP2105 is very similar to the \u003ca href=\"\/nl\/products\/adafruit-cp2102n-friend-usb-to-serial-converter\"\u003eCP2102N\u003c\/a\u003e. Except, instead of having a single serial UART port, it has two. One is 'standard' and one is 'enhanced' - you'll get both enumerated when plugging in this device, without any hub required!\u003c\/p\u003e \u003cp\u003eThe Enhanced port can do:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eData formats supported:\u003cbr\u003e- Data bits: 5, 6, 7, and 8\u003cbr\u003e- Stop bits: 1, 1.5, and 2\u003cbr\u003e- Parity: odd, even, mark, space, no parity\u003c\/li\u003e \u003cli\u003eBaud rates: 300 bps to 2.0 Mbps\u003c\/li\u003e \u003cli\u003e320 Byte receives and transmits buffers\u003c\/li\u003e \u003cli\u003eModem control signals: CTS, RTS, DTR, DSR and RI\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThe Standard port can do:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eData format: 8 data bits, 1 Stop bit\u003cbr\u003eParity: Even, Odd, No parity\u003c\/li\u003e \u003cli\u003eBaud rates: 2400 bps to 921600 bps\u003c\/li\u003e \u003cli\u003e288 Byte receive and transmit buffers\u003c\/li\u003e \u003cli\u003eModem control signals: CTS, RTS, DTR, DSR and RI\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eLike the CP2102N breakout, we have a USB C connector and the same overall shape, but there are some significant changes. The pins are going to be totally different because we have two UARTs, one on either 'side' of the board. The left side is the Enhanced port, right side is the Standard port. We don't have extra GPIO pads and no indicator LEDs. Also, the bottom row is a 'minimal' output of just the two RX\/TX pads and power pins.\u003c\/p\u003e \u003cp\u003eWe like the CP210x series because it has better driver support than the CH340 and can do very high speeds, and variable speeds without stability issues. Compared to the FT232RL and FT231X, the CP210x has the same capabilities or better, at a great price!\u003c\/p\u003e \u003cp\u003eEach order comes with a fully assembled and tested board. We give you some pin header strips, solder them in to plug it into a \u003ca href=\"\/nl\/collections\/solderless-breadboards\"\u003ebreadboard\u003c\/a\u003e and get access to all the pins.\u003c\/p\u003e \u003cp\u003eFor Linux, you won't need a driver. For Windows, it will automatically grab the driver from Windows Update.
