MACCHIATObin Interface list

 

Introduction

This page offers information on the connectors and interfaces available on the MACCHIATObin boards. It also contains the on-board DIP switch / jumpers settings to configure the board to boot from different sources and CPU/DDR settings.

I/O Ports and connectors


First, let us see what ports and connectors are available on the MACCHIATObin boards. Below is a picture of the MACCHIATObin Double Shot board from top view:

 Note

The 10G copper connectors are only available on the Double Shot version of MACCHIATObin; they are not mounted on the Single Shot MACCHIATObin board.

 

 Note

Ports and connector mapping on MACCHIATObin revisions 1.2 and older can be seen below:

Boot Selection

 

 Note

As of revision 1.3 (MACCHIATObin Single Shot and MACCHIATObin Double Shot), the DIP switches have been replaced with 2x10 100mil pin header. When working with jumpers, an "ON" entry in the tables below means that a jumper is placed, whereas "OFF" means no jumper is placed.

 Note

The 2 GHz CPU clock is only available on the Double Shot version of MACCHIATObin; the Single Shot MACCHIATObin board supports up to 1.6 GHz processing speed.

 

PCIe reset fix (up to rev 1.2)


To see how to fix your MACCHIATObin board (rev 1.2 and lower) to support correct PCIe reset when plugging in GPUs, see MACCHIATObin (up to rev 1.2) PCIe reset fix.
