This is a black anodized aluminum enclosure for the NucleoTNC PCB.  This fits the Rev B NucleoTNC PCB.  (The Rev A board will work, but the power LED will need to be bent into position.)  The assembled enclosure is 103x71x25mm.

This enclosure comes with two metal halves that fit together, a front face plate with holes for the indicator LEDS and a a rear plate with holes for the Nucleo32 USB connector, the reset button, and the 3.5mm jack.  The front and rear plates are made of FR-4 PCB material and have white and silver lettering.

The Nucleo32 board must be raised off the PCB by 1.6mm using a spacer in order fit in the case.  The Nucleo32 should be properly soldered to the PCB, rather then press-fit into the PCB to prevent accidental shorts and possible damage to the Nucleo32 board.

You will receive a metal enclosure in two parts, a front plate, a rear plate, and 8 M2.5x5mm screws.

You will need a 2mm hex driver or allen wrench to assemble the enclosure.
