As an upgraded version of the Wio-E5 CAN Dev Kit, it consists of a Wio ESP32 CAN bus Dev Board, an antenna(EU868/US915), a U.FL antenna, and a waterproof case.

Different from the previous Wio-E5 CAN Dev Kit, it's embedded with a highly-integrated ESP32-C3 chip, built around a 32-bit RISC-V chip processor with a four-stage pipeline that operates at up to 160 MHz. This chip has been installed with a complete 2.4GHz Wi-Fi subsystem which means it supports Station mode, SoftAP mode, SoftAP & Station mode, and promiscuous mode for multiple Wi-Fi applications. It works under an ultra-low power state, also supporting features of Bluetooth 5 and Bluetooth mesh. There are 400 KB SRAM & 4 MB Flash on the chip, allowing for more programming space, and bringing more possibilities to the IoT control scenarios.

It uses the Wio-E5 STM32WLE5JC module as the Long Range controller which supports the Long Range protocol on the global frequency band with a long-distance transmission range of 10km(ideal value in open areas).

And this user-friendly board provides rich interfaces including Grove connectors and male/female pin headers for you to connect sensors and modules with different connectors and data protocols, saving time on wire soldering. 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.

Highlighted Features

• Outstanding RF performance: Powerful ESP32-C3 SoC and U.FL antenna that supports WiFi/Bluetooth connection over 100m. It also supports a Global Long Range frequency plan with a long-distance transmission range of 10km(ideal value in open areas)
• 2 Independent CAN FD Interface: Supports CAN FD, CAN2.0 communication
• High extendability with various sensors: full GPIOs led out to rich interfaces, including Grove modules for GPS, environmental detection, etc
• Support industrial standards: 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
• Easy to use: User-friendly IP66 waterproof case for better outdoor deployment and enables temporary use when lacking an external power source

Applications

• Long Range sensor network management: Many sensors in the industry are transmitted through CAN BUS. With the Wio ESP32 CAN Dev board, you can use the onboard CAN BUS function to read the sensors and send the data through Long Range.
• Car hacking: Since the circuit board can receive 7-28V input, the user can connect the circuit board to the OBD interface, and get the data of the car.
• CAN Gateways: Since it enables the possibility of connecting different CAN networks (or sub-networks) with different baud rates and protocols, or integrating with CAN with different network types, such as Ethernet.
