DESCRIPTION

Shield Board for Use with

DC2321A Dust Demo Board

Demonstration circuit DC2510A is a shield board for use

with the DC2321A Dust

application demo board. This

board is designed to allow users to build their own custom

application circuits directly on the DC2321A with access

to all pins of the LTP5901-IPM Dust mote.

The board offers footprints of common sensor and IC

packages as well as prototyping space for routing. The

following footprints are included on the board:

TOP BOTTOM

n MSSOP-10 (×2) n SOT-23 (×4)

n TS8 (×2) n TSOT-23-8 (×2)

n SOIC-20 (×2) n SSOP-20 (×2)

n DFN-20 (×2)

Power rails and grids of copper pads (in both 2mm and

2.54mm pitch) form a solderable breadboard, and the IC

footprints allow easymounting of surface-mount packages.

Each pin on the footprints and headers also connects to

a copper-plated hole for easy wiring.

BOARD PHOTO

The headers on the board are designed to fit into the

LTP5901-IPM header layout on the DC2321A. The long

pins of the headers allow wiring below the board and give

users a place to clip grabber leads.

Theheadersarealsostackable,allowingmultipleDC2510A

boards to be connected vertically, all with access to the

pins on the DC2321A. This allows a user to create different

applications on multiple DC2510A boards and swap them

out or combine them as desired.

Please refer to the DC2321A demo manual and

LTP5901-IPM data sheet for operation information and

input limits. The application section of this demo manual

describes the system level functionality of this board and

the various ways it can be used in early design prototyping.

QUICK START PROCEDURE

Instructions

To use DC2510A, you will need to connect a sensor to the

board. This device can be soldered onto the grid of copper

pads, attached to one of the provided SMD footprints, or

inserted into the headers directly (if it is a through-hole

part such as a thermistor).

There are a few inputs and interfaces for receiving data:

1. UART

2. I2C

3. SPI

4. ADC (×4)

5. GPIO (×4 default, up to 18)

Table 1 shows which of these inputs can be read from

the DC2321A GUI through the Mote Measurement Set-

tings dialog. This allows users to start taking sensor

measurements out-of-the-box without reprogramming

the DC2321A. However, any of these inputs can be used

if a custom program is written.

Some sensors can output a voltage that is suitable for ADC

measurements (ADC abs max = 1.98V), or may have an

integrated serial port. However, other sensors may require

an additional ICto read the measurement andcommunicate

with the mote.

General Notes

•The copper rails on DC2510A are not connected to

anything by default, and must be wired by the user.

•SMD footprints on the top and bottom of the PCB share

plated holes. Only one IC per each set of plated holes

should be populated at any time.

• Do not connect USB power to any pin on the mote.

• Pull-up resistors should be pulled to VSUPPLY.

•Any input with a voltage applied when VSUPPLY is not

powered can power the mote through a sneak path.

Combining Application Circuits

Because DC2510A is stackable, a user can make custom

applications on several different boards and connect all

of the boards together to combine the circuits. This can

be useful if a user runs out of routing space on a board,

or if an additional SMD footprint is needed.

Additionally, if a different GPIO pin is tied high on each of

these boards, data from these circuits can be read from

a single program which checks the state of a GPIO to

determine if a particular sensor circuit is present.

SMD Soldering Instructions

The footprints for U3 and U4 allow ICs with GND paddles

to be mounted using a soldering iron rather than a heat

gun. The recommended procedure is as follows:

1. Place the IC onto the footprint as it will be soldered;

solder the four corner pins into place on the copper

pads.

2. Turn the board over and touch the soldering iron to both

the paddle and the plated hole. Quickly apply solder to

the junction.

3. Turnthe board back to the original orientationand solder

the rest of the pins.

4. Wire the paddle to its destination on the board.

5. Wire the pins to their destinations on the board.
