A WARNING to begin… Any time that you plug the device into a USB port, please make sure that you have both antennas connected. Use the tiny antenna that is included with the SEEED Studio device when you open the box to press the boot button when flashing your device.
I printed my parts on a Bambu A1 using the AMS, so I split the body and did a multicolor print. I have included that file as a .3mf if you have the ability to switch filament mid-print.
Print the pieces face down. While it is printing, solder the positive and negative leads from the battery holder to the bottom of the board. Once printed, screw the battery holder into place in the bottom of the enclosure. Slide the pins of the nRF52840 and SX-1262 into the cradle on the bottom of the enclosure. Secure it with double-sided foam tape. You may need more than one layer of tape.
