Introduction to the Itron Riva Dev Kits The purpose of this Guide is to give you a fast path to understanding which Itron Riva Dev Kit is best for your development goals. Itron offers 3 kits: Itron Riva Dev Edge kit Itron Riva Dev Edge RF kit Itron Riva Dev Edge PLC kit These Itron Riva Dev Kits provide a combination of boards and accessories, giving you a way to quickly prototype and develop solutions for Itron s OpenWay Riva Network. Note: These Itron Riva Dev Kits are for development use only. They are not meant for use in production products. Prototyping your solution with these development kits will prepare you to deploy your solution on production level hardware. Each kit includes several Itron Riva Dev boards. The table shown here compares the features of each board:
Itron Riva Dev Edge Kit Itron Riva Dev Edge boards provide the core processing capability, along with the memory and control logic. The Itron Riva Dev Edge RF board is stacked on the Edge board to provide a 900 Mhz 802.15.4g radio used for mesh networking. In the kit, one Edge board can be configured as a mesh network ROOT device, the other as a mesh network NODE device. These Itron Riva Dev Edge boards are full featured, including built-in Ethernet port, two USB host ports, two 40-pin expansion connectors, and an additional 4GB of emmc flash memory. Itron Riva Dev Mini Kit Itron Riva Dev Mini kit includes a Mini which can be configured as a NODE device. The Mini offers a smaller form factor for a node designed to provide RF communications with the 900 Mhz 802.15.4g radio. In addition to the radio, the Mini has a single mini-usb port and a single 40-pin I/O expansion connector. Due to the smaller form factor, the Itron Riva Dev Mini board does not have the on-board Ethernet or the additional 4GB of emmc flash memory. Two Edge boards are also included in the Mini kit, one of which can be configured as a mesh network ROOT device, and the other as a mesh network NODE device. Note: The Edge and Mini are software compatible. Applications written on one can run on the other. The Edge and Mini are Linux-based systems, providing an open and well-known software environment. Applications developed for Edge and Mini are software compatible with other Itron products, including: SmartNIC, CAM, and Itron Riva Electric Meters. Itron Riva Dev LE Kit Itron Riva Dev LE kit includes one Itron Riva Dev LE board which can be configured as a NODE, and one Edge board which can be configured as a ROOT device. The Itron Riva Dev LE provides very low lowenergy (including battery) operation. To achieve this low energy, the LE has a small subset of the functionality provided by the Edge and Mini: no Ethernet, no USB, and a very small memory footprint. However, the LE does include a 900 Mhz 802.15.4g radio and a 34-pin I/O expansion connector. Note: The LE is not software compatible with either the Edge or the Mini: applications written for LE can only run on LE. Individual Boards Described here are the individual boards offered in our development kits. Itron Riva Dev Edge Board
All three kits contain the Itron Riva Dev Edge board stacked with an Itron Riva Dev Edge RF board. This stack provides the processor, memory, control logic and RF communications for the ROOT on the network. Additional boards can be plugged onto the two 40-pin headers. For example, to add Power-Line Carrier communications, the Itron Riva Dev Edge PLC board can be added to the stack. Note: The two 40-pin expansion connectors allow for a wide-range of 3rd party expansion boards to be added. Serial, GPIO, A/D, I2C, and SPI interfaces are provided. Some example of boards created by thirdparty vendors include: I/O expansion, methane detection, and earthquake detection. A summary of the key hardware features provided by Itron Riva Dev Edge board include: Single 5VDC Supply: The Edge requires a single 5 VDC at 2A power supply. Some versions of the Edge use a 5VDC barrel connector. Others use a 5VDC micro-usb power connector. Single J8 4-Pin Serial Console: Located on the bottom of the Edge is a single 4-pin, white connector. This provides a serial console for use by the Linux-based firmware that ships on the board. Pin Number Description J8-1 UART0_TX J8-2 UART0_RX J8-3 Do Not Use J8-4 GND Single 10/100 Ethernet Port: Located on the end of the board, near the 5VDC power connector, is a 10/100 Mbps Ethernet Port. The most common use of this Ethernet port is to connect to the Internet. Especially when configured as a ROOT/Gateway device, this provides access to a NTP (Network Time Protocol) server. Dual USB A Host Ports: Two USB A Host ports are provided on the board. However, only the bottom USB A port is available for use with USB peripherals. The top USB host port is reserved for use as an Ethernet over USB port. isom: The isom is an Itron developed System on a Module. As shown by the photo below, the isom is the large silver square on the Edge Processing core. The isom contains the following: TI AM3356 ARM Cortex A8 32-bit Microprocessor at 450 Mhz 256 MB of Flash Memory 128 MB of RAM Memory Power Supply
Clock Logic Reset Logic Early Power Fail Detection Logic 4 GB emmc Flash Memory: In addition to the 256 MB of flash memory in the isom, the board provides an additional 4GB of emmc Flash Memory. Two 40-Pin I/O Expansion Connectors: Two 40-pin I/O Expansion Connectors are provided to add additional boards with various I/O requirements. The connectors provide all major I/O types, including: Serial GPIO A/D I2C SPI Definitions for the pins on the two 40-pin I/O expansion connectors are provided below. Key software features of the Edge board include: U-Boot Boot Loader Linux Kernel Device Tree Busybox Shell Linux based File System (firmware) Itron Riva Dev Mini board The Itron Riva Dev Mini is a small form-factor version of the Edge board. The Mini combines the CPU function and the RF communications capability into a single-board with a single 40-pin connector. The 40-pin expansion connector provides access to several I/O connector options including serial, GPIO, A/D, I2C, and SPI, but the Mini does not have Ethernet Port, Dual USB A ports, or emmc (4GB). Key software features of the Itron Riva Dev Mini board include: U-Boot Boot Loader Linux Kernel Device Tree Busybox Shell Linux based File System (firmware) Itron Riva Dev LE board
The Itron Riva Dev LE (Low Energy) is a small form-factor board for use in low-energy or battery powered applications. The board provides a 34-pin expansion connector for I/O expansion: serial, GPIO, A/D, I2C, and SPI. A summary of the key hardware features provided by Itron Riva Dev LE include: Wide range of power supply, from 3VDC to 9VDC, including battery operation Very low power usage STM32L486 CPU w/1mb of Flash and 128Kbyes of RAM ADF 7030-1 Radio Transceiver SKY 66 FEM (Front End Module) 34-pin expansion connector: serial, GPIO, A/D, I2C, and SPI A summary of the key software features provided by Itron Riva Dev LE include: Itron SPLC - Sensor Programmable Logic Control Software FreeRTOS (if needed) Itron Riva Dev Edge RF board The Itron Riva Dev Edge RF board contains a 900 Mhz IEEE 802.15.4g radio core, driven by a DSP (Digital Signal Processor). The board also includes 40-Pin I/O Expansion Connectors so additional boards may be placed on the stack.
