The modularity of the controller

KNX extension module
Connecting side modules

Extension modules are small boards installed inside the case of the Wiren Board 5 and extend its functionality: additional ports RS-485, RS-232, relay outputs, etc.

The controller has two slots for connecting extension modules. Each module has 3 external terminals.

Input/output modules dock with the side connector on the WB5 on the right side of the case, adding 8 to 16 digital or analog ports.

Up to 8 modules can be connected in series: up to 4 input modules (type I) and up to 4 output modules (type O and I/O).

Модуль резервного питания - additional mezzanine board is installed on the second level in the controller case.

Contains Li-Ion (Li-Pol) battery capacity of 1800 mAh, provides the controller up to 3 hours of opertation.

Wireless interfaces

Cellular module - modem 2G (GPRS), 3G (UMTS) or NB-IoT is installed in the controller during production. Requires a MicroSIM card.

The modem allows you to send and receive SMS, connect to the Internet.

Wi-Fi of the Wiren Board can be configured to work in one of three modes:

in Hotpoint mode, enabled by default (the name is WirenBoard without password, the address of the controller in the generated network is:
  • client mode
  • simultaneous operation in both Hotpoint and client modes

Bluetooth 4.0 (Bluetooth Low Energy) — you can track the proximity of other Bluetooth devices, such as a mobile phone or Bluetooth tag.

USB stick Z-Wave gives support for standard Z-Wave devices.

433MHz Packet radio - the RFM69H radio module is installed in the controller during production.

Allows you to connect Noolite devices, Oregon sensors to the controller.

Wi-Fi, GSM and 433 MHz radio antennas are connected to SMA connectors.

If the GSM signal is weak, it is recommended to use a remote antenna and place it away from the controller.

Wired interfaces

Ethernet interface supports 10/100 Mbps. In revisions with 5.8 there is a second Ethernet port.

Так же присутствует один порт USB 2.0. Работает в режиме USB Host или USB Device. Управление питанием отдельных USB-устройств описано в статье USB port power supply.

Configuration is set through the section Configs of the web interface

RS-485 — two-wire bus communication standard.

The controller has 2 RS-485 ports + 2 more ports can be added by RS-485 extension modules.

The article RS-485:Physical connection will help you to choose and lay cables correctly.

Setting up the connection of devices is carried out in the web interface.

Basically in Wiren Board, driver WB-mqtt-serial works through the system of MQTT-messages with connected RS-485 devices.

CAN is the standard for two-wire bus communication. The controller is multiplexed (output to the same terminals) with a second RS-485 port.

1-Wire — is a bus for connecting external sensors on two or three wires. Since this is a bus, you can connect multiple devices to the same 1-Wire port. The controller software supports the connection of DS18B20 type temperature sensors.

It is convenient to use +5V output to power the sensors. It is protected from short circuit and high voltage. When the controller is powered by a battery, the +5V output remains active. There is also a software control of this output (it can be disabled).

Universal inputs/outputs A1-A4

Universal channel Ah combines three functions and can work as:

Resistive inputs R1 and R2

Can operate in modes:

  • resistance measurements 1-30kω
  • voltage measurements in the range of 0-3.0 V
  • digital input

"R2 input only is only in version 5.3."

"*" depends on the hardware revision

All inputs are protected against supply voltage (up to 28 V) and impulse noise.

Type "250" terminals are used as interface terminals in the controller. These are self-locking clips. When the cleaned single-wire is inserted into the socket, it is automatically clamped with a spring latch. To insert stranded wires, it is necessary to press the spring by pressing the clip button. The button has a slot for a screwdriver. To remove the wire, you need to press the spring by pressing the clip button and pull out the wire.

Other interfaces

Debug port - you can directly access the controller console by connecting to it. Through it you can also interact with the bootloader and monitor the operating system boot (serial console).

"Buzzer" — beeps, its frequency is adjustable.

The real-time clock RTC is powered by an internal backup battery.

Revisions 5.3 and 5.6 also contain:

  • IrDA
  • Digital audio output - S/PDIF, TOSLINK connector.


A separate hardware watchdog that reboots the entire controller on power when the software freezes.

Hardware watchdog disable

Power Supply

The controller has three external inputs for power connection:

  • DC jack - standard plug connector (5.5x2.1mm) on the left side of the case.
  • Terminals Vin and GND in the controller of audit 5.8 and above: two terminal Vin, to which you can connect two independent power supply for redundancy. The grounds of the power supplies must be connected and connected to the GND terminal.

It is possible to simultaneously connect the sources to different inputs, including different voltages.

For backup power, you can connect the internal module WBMZ-BATTERY with Li-Ion (Li-Pol) battery.

Valid power range is 7-28V. The average consumption of the Board is 1.5-2 watts. But since the GSM module pulse consumes up to 8 watts, it is recommended to use power supply units with power not less than 10 W.
