We made this device for our own needs, but seems this is a device that any automotive electronics specialist must have.
based on BusBee, redesigned for more stable and noise - free operation. 12v operation possible through external adapter (included).
4-channel operation, compatible with BusBee software ( don’t miss to visit www.usbee.com for one!)
What we can do with it:
We can log and decode almost any serial bus - I2C, Microwire, CAN, UART, 1-wire etc.
One example is below. It is MCP2515 CAN controller logged, SPI protocol between MCU and controller itself:
