NanoBoard 3000 - Diagnostics Interface

Frozen Content

To facilitate board testing using automated test equipment, the NanoBoard 3000 provides a diagnostics ATE interface, courtesy of a PCI Express (PCIe) edge connector.

PCIe connector - providing
access by external automated
test equipment.

The connector provides an SPI link to the board's Host Controller FPGA (NanoTalk Controller), as well an interface to the following board resources:

  • Board ID (1-Wire) memory device
  • Host JTAG (Hard and Soft JTAG chains)
  • Video output
  • User I/O
  • ADC
  • DAC
  • Audio System
  • MIDI
  • Power PWM drivers
  • RS-232
  • RS-485
  • PS/2 Keyboard
  • PS/2 Mouse

Power (5V) and ground lines are also fed to the connector.

The interface – and the I/O signals it conveys – is reserved. It is used during board manufacture and is therefore not for general use.

Location on Board

The connector, labeled 'ATE' (and designated J33) is located on the left-hand edge of the board.

Schematic Reference

The ATE connector can be found on Sheet 24 (CON_NB3000_ATE_INTF.SchDoc, entitled ATE Interface Connector) of the motherboard schematics.
