It is intended to be set up as a small home-server for automation purposes. It comes with Debian Linux as operation system but without any specific user programs by default. However, the whole board support package is publically available as open source software, thus it s possible to run any desired Linux system on it. Duckbill 2 EnOcean is a special version of Duckbill. Duckbill 2 EnOcean has a built-in add-on module containing a TCM310 EnOcean module. 2.1 Features based on Freescale s i.mx28 with ARM9 core and with up to 454 MHz power supply 5V via USB Plug Network interface: Fast Ethernet (RJ45 jack) Operating system: Debian with recent Linux Kernel (see software documentation) RAM Memory: DDR2-RAM 128 Mbyte - 8 Meg x 16 x 8 banks Flash Storage: >= 2 GB, 8 bit wide emmc optional: 4 Bit wide micro SD Socket Interfaces: Ethernet, USB 2.0 Device, EnOcean 3/9

2.2 Applications 2 INTRODUCTION 2.2 Applications The Duckbill can be operated either with an USB power adaptor or plugged into an USB port of your router.

Since Duckbill devices run Linux you are totally free to install additional software components.

4 2.2 Applications 2 INTRODUCTION 2.2 Applications The Duckbill can be operated either with an USB power adaptor or plugged into an USB port of your router. The connection to the home network is made via Ethernet. The Duckbill product series is an simple and fast approach to connect various components of your home automation and/or solar systems to your personal cloud or the Internet of Things. You can use the emmc or the optional micro SD card to store log files, databases, etc. Since Duckbill devices run Linux you are totally free to install additional software components. The connection to the EnOcean actuators and/or sensors is established via the TCM310 module which is wired to the internal application UART of the i.mx28 processor. 2.3 Handling This electronic component is sensitive to electrostatic discharge (ESD) when used without a case. Please handle it only in an ESD protected environment. Please note that any modification like soldering pins to the board voids warranty. 4/9

4 OVERVIEW 2.4 Programming The Duckbill is programmable in all common programming languages which are available for Linux. This includes e.g. Perl, Python, C/C++, Bash/Shell, PHP and many others.

5 4 OVERVIEW 2.4 Programming The Duckbill is programmable in all common programming languages which are available for Linux. This includes e.g. Perl, Python, C/C++, Bash/Shell, PHP and many others. The open software approach enables a comprehensive further development of software by the community. 3 Technical Data 3.1 Absolute Maximum Ratings The following ratings provides the DC absolute maximum operating conditions. Stresses beyond those listed values may cause permanent damage to the device.

system status. The LED s red pin is active high and accessible via i.mx28 s GPIO3 21.

6 LED 4 OVERVIEW LED Duckbill 2 EnOcean has one dual-color LED to indicate overall system status. The LED s red pin is active high and accessible via i.mx28 s GPIO3 21. The LED s green pin is active high and switchable via i.mx28 s GPIO3 20. Figure 2: Position Status LED Additionally, there is a three single LEDs to indicate EnOcean operation. All of these three single LEDs are active low and accessible via i.mx28 s GPIO3 24 (blue), GPIO3 25 (red) and GPIO3 2 (green). Figure 3: Position EnOcean LEDs 6/9

7 Switches 4 OVERVIEW Switches Duckbill 2 EnOcean has two switches. Figure 4: Position PSWITCH SW1 is connected to the i.mx28 s PSWITCH signal. Figure 5: Position 1 SW3 Figure 6: Position 2 SW3 SW3 is connected to the i.mx28 s GPIO3 3. There are two different variants where the SW3 switch is located, see Figure 5 and Figure 6. The latest devices will be shipped with SW3 on location shown in Figure 6. The position of the switch is visible from the outside of the case. 4.3 SD Card Connector Duckbill 2 EnOcean is equipped with an SD card connector. It is 4 bit wide connected to the i.mx28 SSP2. It can be used for data logging applications. 7/9

8 4.8 Hardware Revision Detection 4 OVERVIEW 4.4 Ethernet Interface The Ethernet interface MAC0 of the i.mx28 is connected to an SMSC Ethernet PHY LAN8720. The PHY s reset pin is active low logic. The LAN8720 s nint/refclko signal is connected to i.mx28 s GPIO Booting Duckbill 2 EnOcean is able to boot an operating system from the emmc. If a bootable image is flashed to the emmc Duckbill EnOcean will boot from it. The required start-up time from powered-off to full functional is below one minute. 4.6 Preinstalled Firmware The device comes with a pre-installed firmware. This firmware is based on I2SE s STIB ( I2SE/stib), an open-source solution to ease custom firmware builds based on Debian releases. It brings a simple EnOcean to Ethernet gateway function which uses ser2net ( projects/ser2net/). The device is configured as DHCP client by default. The ser2net daemon listens on TCP port 5000, thus it s possible to receive and send EnOcean telegrams via network. 4.7 MAC Address The device has one MAC address programmed in the OTP memory of the i.mx28 Processor. Each OTP register is 32 bit / 4 byte long while each MAC address is 6 byte long. Linux platform support for Freescale i.mx28 based boards usally assume, that only the last 4 bytes of a MAC address are defined in the OTP section. Thus the first three bytes (OUI) are choosen based on the Device Tree information and combined at runtime with the OTP part to form a full MAC address. Thus for I2SE Duckbill devices, I2SE s OUI 00:01:87 is used and it results in range 00:01:87:XX:XX:XX for the interface. OTP Register Name HW OCOTP CUST0 Usage Stores the 4 least significant bytes of eth0 mac address 4.8 Hardware Revision Detection Duckbill provides pull-up and pull-down resistors for hardware revision detection. Pin LCD D17 (GPIO1 17) Duckbill pull-down Duckbill 2 pull-up This information can be used by software to find out which Duckbill revision it is running. It can not detect which addon PCB revision (SPI, EnOcean etc.) is used. 8/9
