About the Nt10 PCB
Nt10 is an open source PCB design by evyd13, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 40 × 16.1 mm, with 8 components from 7 distinct parts.
Other key parts include the USBLC6-2SC6. By type, the board carries 4 connectors, 2 resistors, 1 IC and 1 fuse.
It belongs with the keyboards designs in this gallery.
From the project
Replacement PCBs for the FC660m, FC750r and FC980m.
The nt-10 is a USB-C daughterboard designed to fit the Leopold range of keyboards. At the time of writing those are the:
Upon removal of the old (probably Mini USB) daughterboard, carefully insert the nt-10 and make sure the USB-C connector fits the cutout in the case. If it does not fit, you can use a small file to increase the cutout size.
You might have to swap the wires on some boards, I had to on the 980m. Lift up the tabs using tweezers or a small knife (don't hurt yourself!) and take out the wires, then press the tabs back down and insert the wires in the correct order.
