Demonstration kit Introduction
The Demonstration Kit (DK) is designed to make it easy for the user to evaluate the onboard
module, develop an application and build prototypes very quickly. The kit includes two Demo
Boards (DB). The demo board contains the selected module with embedded protocol and
associated support circuits. The boards are delivered with a preprogrammed co-processor
firmware and can easily be operated using a PC terminal emulator. For using the
preprogrammed firmware, please see [1].
Your Demonstration Kit contains the following items:

This User Manual describes how to use the Demonstration Kit and provides detailed
documentation for the Demonstration Board.
The Demonstration Kit includes what you need to evaluate the RF performance of the modules,
develop your own application interfacing the modules, and can also be used to build a prototype
of your application on the RC1880 module.
Demo Board Introduction
The Demo Board contains an USB connector, USB to serial converter, LEDs, voltage regulator,
power switch and programming/debug connector. All I/O signals are routed to holes at the edge
suitable for 2.54 mm pitch pin headers.

I/O connection
All pins to the module are available through standard pin rows using a pitch distance of 100
mil (2.54 mm). These pins are connected to 4 x 10 pins holes named P4 to P7. The table
below gives an overview of the edge connectors and their logical signals. Details on the
RC1880 pinning can be found in [2].

Prototyping with the RC1880DB
The RC1880 demonstration board is well suited for prototyping/breadboarding. With all I/O pins
easily accessible at the edge, connection to external boards can be made through board
stacking with standard pin headers or cabled with standard 2.54 mm pitch cable.
With angled header mounted on I/O connector, the demonstration board can also be mounted
vertically in other boards with 2.54mm pitch connectors.
Battery connectors on the bottom side are available for self powered demos. The demonstration
board includes an option to mount a CR2032 battery holder on the bottom side. Suggested
part:
Harwin S8211-46R, available at Digi-key part number 952-1735-2-ND or Mouser part number
855-S8211-46R. Battery clip is not default mounted.
The idea is that an external application specific circuitry/sensors etc easily can be connected
to the demonstration board as a proof of concept for the final product.
The demonstration board is built to fit a commercially off the shelf enclosure named Router
Cube from New Age Enclosure. Available at Mouser. The demonstration board is not delivered
with enclosure. Machining for connectors/antenna is required.

RC1880DB PCB and Assembly layout
The PCB is a simple 2-layer board where Layer 2 is used as ground plane. The laminate used
is standard FR-4 board material. The PCB is 1.6mm thick. Full resolution layout and assembly
drawing are found in [4].
Figure 4. RC1880 PCB component placement, top side
Programming/debug connector
Programming debug connector is 10 pins JTAG/ARM connector with 1.27mm pitch. Both
normal JTAG and compact JTAG (cJTAG) is supported. For making custom specific firmware
to run on the demonstration board please start with [3]
