| ============= | ||||
|  | ||||
| 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). | ||||

|  | ||||
| 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. | ||||
