1Summary / Introduction
The Demo Board belongs to the product family WiMOD and is part of the WiMOD Starter Kit. It
provides a basic platform for using and testing the WiMOD radio modules together with several
sample applications. Thus it can be used to evaluate all WiMOD radio modules and find out
their capabilities.
1.1 Key Features

- USB interface for communication with a PC
- Power supply by USB or battery
- 3 push buttons and 2 DIP switches
- 4 LED indicators
- Temperature sensor with 2-Wire Serial Interface
- Buzzer and potentiometer
- Expansion port (I/O connectors)
1.2 Supported Radio Modules
The Demo Board currently supports the following radio modules:
- iM170A
- iM201A
- iM221A
- iM222A
- iM240A
- iM820A
- iM860A
- iM871A
- iM880A, iM880B
- iM881A
To use one of the radio modules in combination with the Demo Board, the module has to be
soldered on the corresponding Adapter Board (see chapter 4).

2Functional Overview
The WiMOD Demo Board provides several functional units and can be used to demonstrate
and evaluate the different WiMOD radio modules. The desired radio module must be soldered
on its specific Adapter Board (see chapter 4) which can be plugged on the Demo Board.
All functional units of the Demo Board are shown in Figure 2-1. These are the power supply unit
(via USB or battery), the user interfaces (USB, led, button, buzzer, potentiometer, sensor), the
expansion header (RM connector) for the Adapter Board, and the I/O connectors. The Demo
Board user interfaces and most pins of the attached radio module are made available via the
I/O connectors. Therefore it is possible to connect the radio module to the user interface by
using jumpers or connecting cables. Furthermore it is possible to connect external target boards,
sensors or test equipment to these connectors.

2.1 Power Supply
The Demo Board and the attached radio module may be powered from either two “AAA” size
batteries or from the USB bus when connected to a USB port on a PC. The sliding switch S1
toggles between these power sources and must be switched to the wanted power source. In
position “USB” the USB bus voltage together with a voltage regulator (3 V) is used. In position
“BAT” the battery voltage is used directly. LED 6 is turned on when the Demo Board is powered
on. Additionally LED 5 is turned on if a USB connection to a PC is established. It is
recommended either to use the battery or the USB power, thus S1 can be used as on-off-switch.
To supply the radio module with power jumper JP1 must be set. Furthermore it can be replaced
by an ampere meter to measure the current of the radio module. Note: Some adapter boards
are equipped with a boost converter to increase the radio modules supply voltage (e.g. iM871A
AB_05). In this cases the current measurement has to be done directly on the adapter board.
Power supply of the Demo Board (except the USB interface) and the attached radio module is
interrupted if push button B4 is pressed. Because all radio modules have a Power-On-Reset
(POR) functionality B4 serves as the “RESET”button.

2.2 USB Interface
The USB interface of the Demo Board can be used for communication between the attached
radio module and a PC. The USB controller (FT232RQ) is turned on once the connection to a
PC is established. This is also signalized by LED 5. The USB interface supports ”USB 1.1“ and
“USB 2.0 full speed“ modes.
The UART interface (TxD, RxD, /CTS, /RTS, /DSR, /DTR, /Ri) of the used USB controller is
available on I/O connector 3 (see chapter 3.2).
Before the USB interface can be used for the first time, the desired hardware driver for the USB
controller must be installed on the PC. If the PC will detect the Demo Board as new hardware
please follow the given instructions to install the new virtual COM port.
For more information see the corresponding website from FTDI [1].
2.3 User Interface
The user interface of the Demo Board provides the following functionalities. Most of them are
available on the I/O connectors (see chapter 3.2).
- USB interface for a serial communication
- LEDs and a buzzer for signal indication
- Buttons and switches for user interaction
- Potentiometer as analog input signal
- Temperature sensor with I²C interface
The Demo Board has six LEDs to indicate a status or an event. Table 2-1 explains the LEDs and
to which connector they are connected to.

jumpers or connecting cables on the I/O connector. They are switched on by a high level signal.
The Demo Board has one sliding switch, four push buttons and two DIP switches. Table 2-2
highlights the functions of these switches and buttons and their availabilities.

Table 2-2: Connections of Switches and Buttons
Sliding switch S1 selects the power supply (BAT or USB) and button B4 interrupts the power
supply when pressed.
The push buttons B1 to B3 and the DIP switches Dip1_1 and Dip1_2 can be connected to the
attached radio module by using jumpers or connecting cables on the I/O connectors. All of
them have a pull-up resistor and pushing a button or shifting a DIP switch to position ON causes
the corresponding pin on the I/O connector to be pulled to GND (falling edge) while releasing
will result in a signal with VCC level.
Other units of the Demo Board are explained in Table 2-3. They can be connected to the
attached radio module by using jumpers or connecting cables on the I/O connectors.

The potentiometer (trim-pot) provides an analog (voltage) input signal. The value is between
GND and approx. 0.7 V.
The buzzer is a piezoelectric sounder and must be externally driven by a signal. Frequency of this
signal must be between 2 kHz and 4 kHz.
The temperature sensor DS75LX is a digital thermometer and thermostat. It measures
temperatures from -55 °C to +125 °C. Resolution of the digital output signal is 9 to 12 bits.
Communication is achieved through a simple 2-Wire Serial Interface (SDA and SCL).

3.2 I/O Connector X5, X6 and X7
The I/O connector consists of the three pin rows X5 (I/O connector 1), X6 (I/O connector 2) and
X7 (I/O connector 3). On the one side (odd pin numbers) they are connected to the user
interface of the Demo Board. On the other side (even pin numbers) they are connected to the
attached radio module via RM connector 1 and 2. Thus it is possible to connect the radio
module to the user interface by using jumpers or connecting cables. Figure 3-1 depicts the
pinout of the I/O connector.

3.3 Programming Connector X3 and X4
All modules can be reprogrammed either by using the integrated programming interface or the
integrated bootloader via UART interface. On the Demo Board the UART has to be connected to
the USB interface on X7. Alternatively the integrated programming interface of the module can
be used to flash a new program into the module.
Connector X4 can be used to connect a programming device for all WiMOD radio modules
(except iM871A which has to be programmed via the programming connector on its Adapter
Board “Wireless M-Bus AB 1”). The necessary programming device depends on the connected
radio module. Table 3-6 shows the pinout of X4.

3.4 Power Connector X8, X9 and X10
The connectors X8, X9, and X10 can be used for voltage measurement or to connect an external
voltage supply. Voltage of the radio module can be measured on X9. X8 can be used to connect
an external voltage (max. 3.6V) instead of the two batteries. For detailed information see the
schematic in chapter 5.1. X10 serves as analog reference voltage for the A/D converter of the
attached radio module. The usable reference voltage value depends on the used radio module
(see the appropriate datasheet).
Warning: Please do not connect a jumper to one of the power
connectors. This would cause a short-circuit and could damage the
Demo Board and the attached radio module.

Boards respectively the pin assignment of the RM connector (X1 and X2) if the Adapter Board is
plugged on the Demo Board. The “Pad Nr.” relates to the pads of the soldered radio module.
All Adapter Boards consist of a SMA connector which is connected to the 50 pad of the radio
module. It can be used for connecting RF measurement equipment or an external antenna. In
this case the RF path of a radio module has to be switched to the 50 pad instead of using the
integrated PCB antenna.

Notes:
1) Pad 28 of the radio module iM240A is internally connected to GND. Thus X2.8 respectively X7.2 of the Demo
Board must not be used when using the iM240A.
2) Pad 26 and pad 29 are reserved at the iM240A and should not be connected when using this radio module.
3) The radio module is powered by an additional boost converter on the Adapter Board.
