3. Panel-Card Connector

The Panel-Card Connector was designed to serve the Panel-Card 57/70 as an evaluation platform and as a deployable base board for all Panel-Cards. It can also be used to develop and deploy Stamp9261 and Stamp9G20 systems.

3.1. First Steps

The Panel-Card Connector makes it easy to put the Panel-Card/Stamp to use. The first steps involve the following:

  • connecting the board to the Panel-Card/Stamp-Adaptor according to Figure 6.6, “Panel-Card Connector setup”

  • connecting the wall adapter to the main supply and to the board

  • connecting RS232 IF-Module via the serial cable to a COM port of a PC

  • starting a terminal program for the selected COM port at 115200 baud, 8N1

  • starting the module by flipping the power switch

  • boot messages of the module are now expected to appear on the terminal

3.2. Power Supply

From an unregulated input voltage between 8 and 35V two voltages are produced:

  • 3.3V for the CPU module

  • 5V for USB

3.3. Connectors

The following connectors are part of the Panel-Card Connector

  • Two 40-pin header connectors (0.1 inch pitch)

  • Ethernet 10/100 MBit

  • USB Host (dual)

  • USB Device

  • RS232 for use with an RS232 IF-Module

  • DC connector for power supply
