Catena 4551 Integrated LoRaWAN Node

Catena 4551 Integrated LoRaWAN Node

The Catena 4551 is a complete single-board IoT device for LoRaWAN projects.

Based on the Murata CMWX1ZZABZ-078, and designed to be compatible with the Adafruit Feather family of development boards and accessories, the Catena 4551 is a great platform for LoRaWAN investigation and deployment. It works well with The Things Network, or any LoRaWAN 1.0 or 1.1 network in the 865 to 923 MHz range.

Lightweight and small (roughly 2" by 0.9"), the 4551 needs no external components to measure and send temperature, pressure, humidity, and lux, powered from USB or two AAA cells.

Because of the embedded FRAM, the Catena 4551 fully meets the requirements of LoRaWAN 1.1, without worrying about EEPROM wearout or wear-leveling, both for ABP and OTAA.

                Integrated sensors
                  • Pressure
                    • Temperature
                      • Humidity
                        • Lux
                        Additional Features
                          • 2K bytes FRAM for LoRaWAN provisioning info and frame counters -- power can be removed completely without requiring a new join to the network, and without losing uplink and downlink count values (required for LoRaWAN 1.1)
                          • 1M byte SPI Flash for bulk data storage, future FoTA firmware storage, etc.
                          • Boost converter for powering from disposable batteries (such as 2x AAA cells) (Note: in contrast to to the Catena 4450, there is no charger in this model. Contact MCCI for information on a variant supporting Li-Po batteries and USB charging.)
                          • USB or SWD for download and debug
                          • Pin-compatible with Adafruit Feather M0 family of boards (some limitations because the of functional differences between the Murata module and the Atmel SAMD21 CPU used in the Feather M0)
                          • Arduino-compatible
                          • Compatible with the MCCI Catena 4450 IoT device
                          • Designed for use with The Things Network (open-source, user-owned IoT network based on LoRaWAN); but can be used with any LoRaWAN-compatible network
                          • Provisions for screw terminals for pulse, analog or digital I/O
                          • Whip, u.FL, or SMA antenna
                          • Open source hardware and software (https://github.com/mcci-catena)

                          MCCI provides a full Arduino / Platform IO board-support package. MCCI also provides libraries to allow rapid prototyping and experimenting, including an open-source LoRaWAN stack that supports the EU868, US915, AS923, AU921 and IN866 regional plans. ST Micro tools may also be used.

                          The Catena 4551 works well with and is tested with The Things Network (an open-source, user-owned IoT network based on LoRaWAN); but can be used with any LoRaWAN-compatible network.

                            Pricing and Availability

                            The Catena 4551 is available for pre-order now, shipping in December 2017. MCCI offers several variants.

                            • The basic board ("BASIC"): ships with 12 and 16-pin terminal strips, unassembled. User attaches antenna (and terminal strips if desired). Whip antennas suitable for 868 MHz and 915 MHz operation are supplied.
                            • The developer board ("DEV"):  assembled unit with screw terminals, terminal strips, AAA battery clip, and whip antennas for US and EU.
                            • The contact monitoring system ("M101"): assembled unit for monitoring up to four contact closures, with screw terminals, 2xAAA battery clip and whip antenna.
                            • The environmental monitoring system ("M102"): assembled unit for monitoring one or more external Dallas Semiconductor "One Wire" sensors and/or a soil humidity/temperature sensor, with screw terminals, 2xAAA battery clip, and whip antenna; for mounting in Stephenson screen (not included).
