General
Ever since we launched our USB2CAN module in the March 2019, we received many favourable reviews from all over the world. We really appreciate the praise, advise, and criticism from all the users.
Based on these feedback, We designed this USB2CAN core module and hope it can helps more people to use this higher cost performance USB2CAN solution in their circuit design conveniently.
Features with small size and various welding modes, you can easy add this core module on your board like X86, ARM, CM4, Jetson Nano,etc, which with USB port and need add CAN-Bus communication function.
The firmware is 100% same as our usb2can module. We also provide the ready-made high reliability reference design files based on this USB2CAN core module.
