ProgRock enclosure

This is an enclosure for a programmable crystal replacement available from QRP labs (https://www.qrp-labs.com/progrock.html). The kit consists of a minimalist controller for a Si5351A clock generator chip and can produce up to three squarewave outputs between e few kHz and approx 300 MHz. It can be GPS disciplined for accuracy better than 1 ppm and up to 8x3 frequencies can be programmed via a serial interface.

The enclosure consists of a bottom- and a top part.
The bottom part holds the PCB and includes a hole through which the RX/TX-signals of the serial interface are accessible. For this and the other connections I use Dupont line connectors, which are glued with two part epoxy adhesive to the enclosure walls next to the holes.
The top part has holes for the power supply (5,5/2,5 mm DC socket), the SMA-connector for the CLK0 output, a header with all the frequency outputs, the connector for the GPS (optional, if not used connect 1pps to ground) and finally a 3-way DIP switch f
