Hardware PCB Figure 1-1 depicts the printed circuit board of the iC880A-SPI. As main interface there are the pin headers for connecting the board to a host system that runs the driver software. A SMA connector or an uFL connector is supplied in order to connect any suitable antenna to this board. -
Page 5: Basic System Concept
Basic System Concept Figure 1-2 shows the basic system concept for the LoRA WAN system. The iC880A-SPI is the central hardware solution for all LoRa based radio communication. It receives and transmits radio messages. Processing of the radio messages as well as the protocol related tasks is done by (external) host system(s). -

…) is outside of the scope of this document, too. Hardware Connection The iC880A-SPI provides SPI – pin headers as main interface to the Linux host system. Before connecting the iC880A-SPI and the host, please read this document carefully. In order to establish a logical connection the host needs to have some drivers installed. - Page 7 Overview confidential than 700 mA. Therefore it is recommended to choose a proper power supply that is able to supply the iC880A-SPI and the host system (e.g. Raspberry PI) at the same time. (See Figure 1-3) Raspberry Pi Raspberry Pi...

19, 21, 23 and 24. Additionally the Reset pin of the iC880A-SPI has to be connected to the host system. On the host side virtually any normal GPIO pin can be used for that. (In the following pin 11 aka. GPIO17 is considered to be connected to the reset pin.) -

(Note: the repository is not maintained by IMST.) That means the user has to take care of it via an additional piece of software. In general there are two possibilities to control the GPIO pin that is connected to the Reset pin of the iC880A-SPI. iC880A-SPI_QuickStartGuide.docx, Wireless Solutions, V0.1... - Page 10 2.2.2.1.2 Possibility B: Control the GPIO pin via a compiled C-Tool / library If the host system is a Raspberry Pi the user can write a small C-Tool to reset set the iC880A-SPI. In order to access the GPIO pins of the Raspberry Pi there is a library called “wiringPi” that takes care of the low level details.

The filef ile lora_gateway/libloragw/library.cfg is used as general configuration file for the whole libloragw system library. In order to fit the needs of the iC880A-SPI, some parameters can be set to the following values prior (re-) compiling the library:... -

If the user wants to send out some demo data with another radio module some care must be taken about the set up type of network.
