Can anyone specifically tell me where to connect UART/TTL on the 4K drone to get access to u-boot / console for rcS file editing? People in the "let's fix it together" has forgotten it or not willing to help, and the thread has no real 4K info on the subject. The 4K components look entirely different than the pics in that thread. EDIT: Figured it out. Posting my findings in the other thread.
