Update to main post:
Please be aware that the payload injection feature for future DIs is currently under review. Due to the recent popularity of my projects and recent information I've been made aware of regarding TPM laws, I've decided to seek legal counsel as to the lawfulness of including this feature. It may be included, it may require an update after you receive it, or I may not support it at all. In such a case, the dongle would be considered a general purpose MCU, and modification of the device by any user to add additional functionality would be officially unsupported. Discussion surrounding this would also be banned from any of my official channels. I do not support piracy and want to keep my projects legal!
