From time to time, you will see diagrams produced by Fritzing, an open-source electronic circuit design tool. You will also see some examples contributed by various users who have been actively contributing their resources to the open-source community e.g. Chiang Mai Maker Club.

The Fritzing diagram provides a brief illustration showing how the hardware and components are to be connected. Sometimes not all the physical hardware used as shown in the diagram. For instance, it is assumed that ALL the ESPresso Lite board in the Fritzing diagrams used are already connected to the a power source via the FTDI-compatible (e.g. UC00A) USB-Serial converter cable at pins DTR, TX, RX, Vin, CTS & GND. The omission from the Fritzing diagram is to make it easier to read especially for novice learners.
