LoRa-E5 CAN Development Kit is based on the LoRa-E5 STM32WLE5JC Module and supports CAN FD, CAN2.0, and RS485 communication. It provides a user-friendly waterproof case and solar charging interface for better outdoor deployment. (Buy with Small Solar Panel 55x70mm 0.5W if you need it in your project)
It consists of a LoRa-E5 CAN bus Dev Board, an antenna(EU868/US915), and a waterproof case. The embedded LoRa-E5 STM32WLE5JC Module supports LoRaWAN protocol on the global frequency band. It leads out full GPIOs of LoRa-E5 supporting various data protocols and interfaces including RS-485, Grove, male/female headers, etc. It would be a perfect choice for fast testing and rapid prototyping of your LoRa IoT projects. Also, the LoRa-E5 STM32WLE5JC Module is the world-first combo of LoRa RF and MCU chip into one single tiny chip and is FCC and CE certified. It is powered by ARM Cortex-M4 core and Semtech SX126X LoRa chip, supports both LoRaWAN and LoRa protocol on the worldwide frequency and (G)FSK, BPSK, (G)MSK, and LoRa modulations.
It features an ultra-long transmitting range of up to 10km in an open area, extremely low chip power consumption which the sleep current is as low as 2.1 uA(WOR mode), and user-friendly interfaces which are developed to unlock the full functionality of the LoRa-E5 module, CAN FD and CAN 2.0 communication, it has led out full 28 pins of LoRa-E5 and provides rich interfaces including Grove connectors, RS-485 terminal, male/female pin headers for you to connect sensors and modules with different connectors and data protocols, saving your time on wire soldering. You could also easily power the board by connecting the battery holder with 2 AA batteries, enabling temporary use when lacking an external power source. It is a user-friendly board for easy testing and rapid prototyping. It is designed with industrial standards with a wide working temperature at -40 ~ 85, high sensitivity between -116.5 dBm ~ -136 dBm, and power output up to +20.8dBm at 3.3V.

CAN stands for Controller Area Network, it is used toallow microcontrollers and devices to communicate with each other within a vehicle without a host computer which allows for control and data acquisition. These devices are also called Electronic Control Units (ECU) and they enable communication between all parts of a vehicle.
Today, you can find up to 70 ECUs in a modern car. CAN is a serial communication bus designed for industrial and automotive applications. For example, they are found in vehicles, farming equipment, industrial environments, etc.
The fuel level, door sensors, odometer, and many more parts of a car have to communicate with each other somehow, and CAN BUS is what they used to do. These CAN-compatible components, which are called "nodes" are connected with a 3-string copper wire, with no central router to govern the flow of data. Every node can hear the messages of every other node.
Every node has an ID, where the ones with the higher priority ID can have the priority to "talk" first while the others "listen". This is to ensure that there are never two nodes talking at the same time. The biggest benefit of CAN-BUS is to be able to just connect components without having to worry about signal routing.

There are two Grove interfaces on board that lead out more functions you will need in your projects. Here we will provide you with some suggestions.
Grovemakes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering are required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill various needs. Not only are these open hardware, but we also have open-source software.
Grove - GPS (Air530)---Provide real-time GPS tracking. Monitor the live trips and save the data for retrieval. Keep a record of the number of days parked.
Grove - AHT20 I2C Industrial Grade Temperature and Humidity Sensor---Monitor and record the temperature and humidity in the vehicle, and alert if it rises above or below the standard-setting.
Grove - 3-Axis Digital Accelerometer(±1.5g)---Sensing data changes for devices' fall detection.
Grove - High Precision RTC (DS1307)--- Provide an accurate real-time clock with the regular clock chip DS1307.
Grove - Ultrasonic Distance Sensor---Provide audible cues and visual aids to the driver for backing up parking, and vehicle proximity awareness.
Grove - Light Sensor v1.2 - LS06-S phototransistor---Use for light measurement, light detection, and light-controlled switch in the vehicle.
Grove - Laser PM2.5 Dust Sensor - Arduino Compatible - HM3301---Use for continuous and real-time detection of dust in the air.
Grove - SEN55 All-in-one environmental sensor---It assembles PM, NOx, VOC, RH, and temperature sensing functionality, delivering up to 8 types of the environmental data signal, sensing in high accuracy and operating for long terms, born for HVAC(Heating, Ventilation, and Air Conditioning) and air quality long years detecting applications.
You can also interact with the devices through a Human-Machine Interface(HMI):
Wio Terminal---Sense and tag the Real-World data with over 300 Groves created by Seeed and visualize through Azure IoT Central Platform to create an end-to-end IoT project.
reTerminal CM4104032---reTerminal is powered by a Raspberry Pi Compute Module 4 (CM4) which is a Quad-Core Cortex-A72 CPU running at 1.5GHz and a 5-inch IPS capacitive multi-touch screen with a resolution of 720 x 1280.
LoRa sensor network management: A large number of sensors in the industry are transmitted through CAN BUS. With the LoRa-E5 CAN Dev board you can use the on-board CAN-BUS function to read the sensors and send the data through LoRa.
Car hacking: Since the circuit board can receive 5-28V input, the user can connect the circuit board to the OBD interface, get the data of the car and send it out through LoRa
