About the SPIFEE PCB

SPIFEE is an open source PCB design by dennowiggle, published on GitHub under the LGPL-2.1 license. It is a 4-layer board measuring 101.6 × 49.9 mm, with 67 components from 15 distinct parts.

Other key parts include the 74LVC2G34GW,125, DS1086LU+, MC68SEC000FU20, 74LVC2G07GW,125 and 74LVC3G06SS8-7. By type, the board carries 37 resistors, 16 capacitors, 6 ICs, 5 diodes and 3 connectors.

It belongs with the retro computing designs in this gallery.

From the project

3.3V Retro computer project => FPGA + RCBUS + CPU boards making a custom system.

The purpose of the card is to use it to learn 68000 programming.

3. Jumper CPURESETN to CPUHALTN, RCBUS pin 20 to pin 63. If signals need to be separate then jumper CPUHALT_N to spare pin on PETER FPGA e.g. spare GPIO pin on PETER GPIO header.

4. If using a socket for the FLASH have the assembly house solder the socket, or use a hotplate and hot air. * If soldering the FLASH part directly it is possible to program a blank FLASH when soldered onto the board from a ROM image inside the FPGA to start. First need to develop the ROM image to do that.
