+
+PCB
+===
+
+The circuit board was designed using KiCad.
+
+PCB footprints are cached in the design files, but are also
+avaliable in a separate repository:
+
+	https://github.com/sharebrained/library-kicad/
+	
+The PCB is a four-layer design. Services such as OSHPark.com have suitable
+four-layer stack ups.
+
+CPLD
+====
+
+The CPLD bitstream is prepared using Altera Quartus tools.
+
+The CPLD is programmed from within the PortaPack firmware, by bit-banging
+the JTAG pins from the HackRF One's microcontroller.
