The schematics for Ollie v2 are now on GitHub. One of the major changes from the original Ollie is the primary component used — Ollie v2 uses the CH344 quad-serial port chip, which, in my view, offers greater stability compared to the XR21V1414 used in the original Ollie. Another big difference is that the CAN functionality in Ollie v2 is built on the CH32 RISC-V MCU, using my custom firmware, set to be released soon. Furthermore, I’ve made Windows and Linux drivers available to simplify the identification of various ports. For macOS users, the manufacturer provides drivers for the serial chip, but unfortunately, at this time, there is no available solution for CAN functionality on macOS.

On Windows, after installing the drivers, COM ports will be renamed in the device manager like this:

On Linux, ports will be renamed like this:
