1. Adopting high-performance STM32G4 series microcontroller, with a running frequency of up to 170M.2. Support CAN2.OA, CAN2.0B, and CAN- protocols for faster speeds.3. Support firmware updates on web pages, easy to use, and open source data.4. Support open source upper computer Cangaroo CAN protocol analysis software.5. Easy to use, with three color LED status indication.Note:Due to different production batches, the appearance is different, which does not affect the use.Input voltage:5VInterface:Type-C power supplyInstructions for use:1. Type-C mother base: connected to the computer through a USB cable2. BOOT startup: After short circuiting and inserting TYPE-C, it will enter BOOT mode and the firmware can be burned again3. Terminal resistor option: Insert the jumper cap to indicate the connection of a 120 terminal resistor4. Output interface: CAN_ H and CAN_ L connected to CAN bus GND can be connected or not5. Insert the computer and the three color lights on the board will light up. Serial devices will appear in the device manager.Colour:BlueMaterial:PCB+electronic componentsSize:45x20mmPackage Contents:1 * USB to CAN moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
