User Guide🔗


The Wirepas Mesh Demo Kit is a ready-to-use Evaluation Tool based on the PAN1780 module in combination with the Wirepas Mesh firmware connectivity stack.

The demo kit consists of 4 sensor nodes which measure and send out temperature values, and one sink which acts as a border router.


  • PAN1780

  • Low Latency (LL) and Low Energy (LE) mode

  • Humidity and temperature sensor (HTS221)

  • Panasonic SMD tactile switch

  • User LED

  • USB-C or battery powered

  • 6-pin SWD interface

Can be optionally assembled but not in the kit included:

  • Panasonic PIR sensor

Board Overview🔗

Sensor Node🔗

1 USB-C connector - X2
You can use the USB connector to power the sensor node.

2 User LED
You can turn the user LED on and off from the web interface.

3 PAN1780 module

4 Temperature sensor - IC6
The ST Capacitive digital sensor for relative humidity and temperature (HTS221).

5 Button - S1
You can use the Panasonic SMD tactile switch (EVPBFAC1A000) to trigger the button event.

6 Switch - S2
Allows you to choose the power mode.

7 Battery holder
You can power the sensor node using the CRC2032 batter holder.

8 SWD interface
Gives you access to the PAN1780 programming interface.


9 USB-C connector - X2
You can use the USB connector to power the sensor node and also to read out the mesh network data.

10 Status LED
Provides information about the sink status.

11 PAN1780 module

Power Supply🔗

You have following options to power the two different devices:

Powering a Sensor Node:

  • You can power a sensor node using a CR2032 coin cell, which needs to be inserted into the battery holder 7.

  • Alternatively, you can power the sensor node through the USB-C connector X2 1.

Powering the Sink:

Power Modes🔗

The Wirepas mesh network has two different modes of operation which you can configure with the switch S2 6:

  • Low Energy Mode (LE): This is used to create networks that run on batteries.

  • Low Latency Mode (LL): This is used when you need data to move really quickly. It's meant for devices that are plugged into power sources.

For more information about the power modes please visit the official Wirepas website.


The user LED 2on the sensor node operates as follows:

  1. Power-On: When you power on the sensor node, the LED1 automatically turns on, indicating that the sensor node is active and operational.

  2. Communication Availability: LED1 remains illuminated to signal that communication is possible from the sink to the sensor node. This indicates that the sensor node is ready to establish a connection with the sink.

  3. Successful Connection: Once the sensor node successfully establishes a connection with the sink, the LED1 turns off, indicating that the connection has been established and communication is active.

  4. You can switch on and off LED1 from the GUI which is described in the Quick Start Guide.

On the sink the status LED 10 shows you that the device is powered.

SWD Interface🔗

The SWD interface gives you access to the module programming interface.


Please be aware that when you program a new application into the device you lose the application that is delivered with the sensor nodes and sink. The original application is not published so you can never return the devices to their default state.

You need following equipment to get access to the programming interface:

  • Debugger for Arm MCU: For example from Segger.

  • Needle Plug: For example the TC2030-CTX-NL 6-Pin.

  • Adapter: Depending on which debugger you plan to use it might be necessary to have an adapter like ARM-JTAG-20-10.
