+rc2014-compat
+=============
+
+A respin of the [RC2014](https://rc2014.co.uk/) ecosystem.  I don't have any
+opposition to building things out of SMD parts (in some ways, I find it
+easier to work with), so some boards might go that way to the extent that
+parts availability allows.  Also, I'd like to keep all board sizes within
+the 100x100mm limit within which PCB fabs offer their cheapest rates (like
+$2 double-sided at JLCPCB, for instance).

+backplane16pcie
+---------------
+
+Who knew right-angle headers and matching sockets would be so hard to come
+by?  This is a respin of backplane16 that replaces difficult-to-source (and
+expensive when you find them) connectors at each end with the connectors
+your newer computer uses for its expansion slots.  A 4-lane PCI Express
+connector has 64 connections inside...perfect for our needs here. 
+Straddle-mount sockets for one end are fairly cheap (under $4 from a
+domestic distributor), and since the mating connector at the other end is
+integrated into the PCB layout, it's basically free.
+
+Beyond that, the board provides support for both extended (second row of 10
+pins) and 16-bit (second row of 23 pins) RC2014-compatible cards.  It breaks
+out both UART connections to 4-pin connectors (note: TX and RX labels are
+intentionally swapped; connect TX to TX and RX to RX), uses any USB-C power
+supply, and provides power-on reset and a reset button.
