i finally finished validation of MNT Reform (Classic) motherboard 3.0 and fixed the little bugs i found and reworked the USB-UART's power supply for a final revision (3.0 D-2). i just ordered some PCB samples of this board that we should have end of next week. then i'll feel confident to produce a 100x batch which will unblock the MNT Reform backorders from last year. thank you for your enormous patience and sorry this took so long to get right.
