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. \ No newline at end of file diff --git a/kitspace.yaml b/kitspace.yaml index ce4a992..85f4473 100644 --- a/kitspace.yaml +++ b/kitspace.yaml @@ -9,3 +9,13 @@ multi: schematic: z80-cpu/z80-cpu.kicad_sch bom: z80-cpu/1-click-bom.tsv readme: z80-cpu/README.md + backplane16pcie: + summary: modular 4-slot backplane with reset and USB-C power + color: purple + gerbers: backplane16pcie/fabrication + eda: + type: kicad + pcb: backplane16pcie/backplane16pcie.kicad_pcb + schematic: backplane16pcie/backplane16pcie.kicad_sch + bom: backplane16pcie/1-click-bom.tsv + readme: backplane16pcie/README.md
