Multipurpose Serial Slice

Version: 1
Status: Complete
License: MIT
Download: /files/project_builds/Serial Slice 1v0.zip

This Slice provides the following ports:
1x RS-485 or RS-232 (top RJ-45)
1x SPI over LVDS (bottom RJ-45)
6x 3.3 volt UART
 
The zip file contains:
Schematics (PDF)
Top CAD view of board (PDF)
BOM (Excel) Design files (Altium)
Gerber files
 
This Slice is intended to be used with the sc_multi_uart and sc_spi (master) software components available through GitHub.
A 1.8432 MHz crystal oscillator is included, as required by sc_multi_uart for transmit functionality. An LTC2870 multi-protocol transceiver is used to provide RS-485 or RS-232, settable using an onboard DIP switch. Other options such as loopback, half/full duplex and rs-485 termination are also settable through the DIP switch. An SN65LVDS047 and SN65LVDS2 are used for LVDS translation.
This slice is only fully functional if used in the Triangle slot. It will work in other slots with reduced functionality.
