Early in my PCB designer career, I didn’t specify much, and unless it was for a specialized project, it probably turned out fine. Fritzing does not let you specify the solder mask, but generates it automatically. You can even design your own PCBs and have them fabricated from the files you design. The next thing you want to do is save the Adafruit bin (parts libraries in Fritzing are called 'bins'). ... // Pitch is angle between sensor x-axis and Earth ground plane, toward the // Earth is positive, up toward the sky is negative. A via may be at the edge of the board so that it is cut in half. 18 V (V. IN – V. OUT) * I. Absolute Maximum Ratings. In fact, just draw right on top of the dimension lines. Fritzing follows that path and makes all the connected pads part of the ground fill. Creating a Ground Plane for Your PCB Design. For your circuit there is no real electrical reason to use a ground plane. The TTGO systems and antennas were connected directly to the SMA connector provided on the TTGO (this was the main reason for … Datasheet, schematic, EagleCAD PCB files, and Fritzing available in the product tutorial; Revision History: As of Feb 5, 2020 - We've made the trace to the enable pin thicker, and added a ground plane which helps keep the enable line clean some high-noise environments. 2. Early in my PCB designer career, I didn’t specify much, and unless it was for a specialized project, it probably turned out fine. This calculator is designed to give the vertical length of a quarter-wave ground plane antenna, and the length of each of the four radials for the selected frequency you have entered. The plane does not necessarily have to be connected to ground. This is to make it possible to solder because if it was just solid the large copper area would take heat away fro the pad too quickly making the solder joint weak.
