			[[File:thecount_pcb.JPG \| right\| thumb \| <center> The Count PCB Layout </center>]]
			'''The Count''' is the first of the HABEES Avionics boards to be 4-layer. This was necessitated by the increased density of components, and, moreso, by the density of the pinout of the databus, which contained over 20 pins in a very small area, with only 2mm pitch. While most of the board is contained in the top and bottom planes, auxiliary signals, and specifically data pinouts, are found in the internal layers. The heater trace is also found in the internal signal layer. <br/>

			Regarding general layout, The Count features two large ground planes for the Iridium & GPS antennas, isolated using stitching vias, and connected to the primary ground planes using just a small 10 mil trace at their tops, to prevent large currents from affecting the antenna planes.<br/>

			The Count also features, naturally, the HONEY connectors on its right side, and HONEY mounting holes at each of its four corners. The majority of sensors & circuits is found in the center of the board, with the GPS located at the top, Iridium module on the left, and connectors/LED's at the bottom left. <br/>
