This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. The DTR pin on the board allows an Arduino target to auto-reset when a new Sketch is downloaded. Pinout matches Sparkfun FTDI Basic boards The paddle on the reset switch is resessed to avoid accidental voltage changes.ĥV or 3.3V operation switchable via onboard switch
#FTDI ARDUINO UNO PINOUT SERIAL#
This is a USB to TTL serial cable, with a FTDI FT232RL usb/serial chip embedded in the head. But its rare for a computer to have a serial port anymore. This is not a problem for connecting to both 3.3V and 5V boards. Adafruit Industries, Unique & fun DIY electronics and kits FTDI Serial TTL-232 USB Cable : ID 70 - Just about all electronics use TTL serial for debugging, bootloading, programming, serial output, etc. Note that this only switches the output voltage on the VCC pin which is used to power the connected device. One of the nice features of this board is a switch on the front of the board that allows the board to be configured to either 3.3V or 5V (power only not IO level). It can also be used for general serial applications. The Uno differs from all preceding boards in that it does not use the FTDI. The pinout of this board matches the similar Sparkfun FTDI Basic boards to work with official Arduino and cloned 5V or 3.3V Arduino boards. The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). The Hobbytronics FTDI Basic Breakout Plus is a breakout board for the FTDI FT231X USB to serial IC.
