The RTC part of the design is fairly small and tucked away in the bottom left corner to be near the Arduino pins needed to provide power and the I 2C connections required by the DS1307 chip. The PCB is shown front and back in Figures 4 and 5. Plus, they sent me an extra board for free - a two for one hidden sale that you might (or might not) get!įIGURE 1. I purchased one PCB for $26.27 and received it three weeks later (really not bad at all).
THE PCB FINALLY ARRIVES!įigures 1, 2, and 3 show the Fritzing breadboard, the schematic, and the PCB views, respectively, that were used to generate the Gerber files that I sent to BatchPCB. Well, after three weeks the PCB arrived and it works! Let’s take a look at it and then go a bit further with Fritzing to start learning how to make parts. We also saw how to take that schematic and create a printed circuit board (PCB) design that we sent off to BatchPCB. We saw how to use Fritzing to take the breadboard design from Part 1 and turn it into a schematic drawing that is crucial for understanding and documenting a design.
In our last episode, we continued learning about Fritzing - a novice-friendly electronics hardware design package that we are using to design a real time clock (RTC) shield for an Arduino.
