+<h3>AXIAL-0.3-KIT</h3>
+
+Commonly used for 1/4W through-hole resistors. 0.3" pitch between holes.<br>
+<br>
+
+<b>Warning:</b> This is the KIT version of the AXIAL-0.3 package. This package has a smaller diameter top stop mask, which doesn't cover the diameter of the pad. This means only the bottom side of the pads' copper will be exposed. You'll only be able to solder to the bottom side.

+This footprint was designed to help hold the alignment of a through-hole component (i.e. 6-pin header) while soldering it into place.
+You may notice that each hole has been shifted either up or down by 0.005 of an inch from it's more standard position (which is a perfectly straight line).
+This slight alteration caused the pins (the squares in the middle) to touch the edges of the holes. Because they are alternating, it causes a "brace"
+to hold the component in place. 0.005 has proven to be the perfect amount of "off-center" position when using our standard breakaway headers.
+Although looks a little odd when you look at the bare footprint, once you have a header in there, the alteration is very hard to notice. Also,
+if you push a header all the way into place, it is covered up entirely on the bottom side. This idea of altering the position of holes to aid alignment
+will be further integrated into the Sparkfun Library for other footprints. It can help hold any component with 3 or more connection pins.

+The device needs 3 voltages: 3.3V, 1.8V and 8V with a 700mA capacity.
+
+Since we operate from 12V battery, a buck regulator is used to derive the 3.3V. Bucks present a lot of noise
+at their input, so there is an LC filter there to avoid turning the cable into a broadband VHF noise emitter.

+The STM32L412 is a reasonably low-cost L4 that offers enough
+flash for an -O2 optimized firmware build.
+
+I ran into issues with erasing / writing flash internally though,
+so I opted for a low-cost EEPROM to store configuration.
+I2C pullups are internal.
+This RC delay circuit facilitates jumping into
+the ROM bootloader with a clean reset
+This connector will accommodate either SEGGER or
+STLINK adapters that need a reference voltage.

+This 5-pole Butterworth is somewhat forgiving of component tolerances
+so it is pretty easy to replicate. You may choose to stuff the pads
+differently and use a 3-pole design instead.

+This unorthodox Class E configuration for 162MHz only outputs +16dBm,
+but achieves a much "cleaner" harmonic output which is essential.
+The input matching networks for the RF ICs are 100 Ohm each and
+they are wired in parallel using 100Ohm traces. The combined impedance
+is very close to 50 Ohms and is fully characterised.

+RF Power Amplifier

+This power amplifier adds more than 17dB of gain for a total
+conducted output power of +33dBm.
+
+It is based on the reference designs in the datasheet, but
+includes a narrowband input matching network to better
+reject harmonics from the backend and a very steep Chebyshev
+low pass filter to deal with a pesky 2nd harmonic that falls
+in the restricted aviation band (324MHz).
+
+Do not combine capacitor values into single components.
+Use them in parallel as designed to better compensate for
+tolerances.
+
+The MOSFET drain is always powered, but the gate bias voltage
+is controlled by the MCU via R11, R12 and C11. The RC delay
+is essential for suppressing spurious emissions during ramp up.
+Firmware instruments ramp-down by pulling this voltage low as
+it enters the "ramp-down" bits of the packet. This mechanism
+bypasses the (broken) TX ramp implementation in the Si4463.

+The Telit SE873Q5 GNSS module is a 1.8V devices so it needs level shifting for both the UART
+and the 1PPS signal. Simple N-Channel MOSFETs do the trick. No need for anything fancy.
+
+The 1PPS signal is inverted, so the MCU IO is configured with an internal pullup and reacts
+to a falling edge instead.

+This type of RX/TX switch needs no DC blocking caps.
+Although it runs on 3.3V, all logic inputs must be well below
+3V, so I opted for 1.8 since it's already available.
+
+The test pads at the output form a coaxial connector
+for pogo pins to automate production testing.
