About the SingleBoard PCB

SingleBoard is an open source PCB design by lostedz, published on GitHub under the ISC license. It is a 4-layer board measuring 120 × 90 mm, with 121 components from 39 distinct parts.

Other key parts include the XC6SLX16-FTG256, TPS562200, W25Q32JVSS and MT48LC16M16A2P-75. By type, the board carries 70 capacitors, 29 resistors, 8 diodes, 5 ICs, 3 connectors and 2 switches.

From the project

A KiCad schematic and board for the target the rest of this repository aims at: the J68-derived 68000 soft CPU running inside an XC6SLX16-FTG256 at 50 MHz, with the MT48LC16M16A2-75 SDRAM of docs/sdram.md and the 3.3 V logic-level UART of docs/uart.md.

A KiCad schematic and board for the target the rest of this repository aims at: the J68-derived 68000 soft CPU running inside an XC6SLX16-FTG256 at 50 MHz, with the MT48LC16M16A2-75 SDRAM of docs/sdram.md and the 3.3 V logic-level UART of docs/uart.md.

This is a concept. The schematic has not been simulated, fabricated or reviewed by anyone, and the board is placed but not routed — it has no tracks on it at all. Nothing here has been checked against silicon. Read Before you build one before spending money on it.

SingleBoard: common questions

How big is the SingleBoard PCB?

The SingleBoard measures 120 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SingleBoard?

121 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the SingleBoard design files?

From the lostedz/SingleBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SingleBoard design in my own project?

Yes, under the terms of its ISC license, which lostedz chose for the repository.
