The Waveshare 10.1-inch PCAP touch display is used in this design. The dimensions of the housing were chosen so that a Hermes Lite 2 pcb with N2ADR filter board pcb and the ATU-100-EXT pcb can be installed. The controls and display of the ATU-100-EXT were positioned on the right-hand side of the housing. Apart from an on/off switch on the rear of the housing, no other controls are provided. It is operated solely via the touch display or via a USB keyboard/mouse combo.

The handles integrated into the side panels also serve as protection for the touch display.

Connectors

The following connections are located on the rear:

Backside

2x USB-3 (connected to the Raspberry Pi5)
1x USB-2 (connected to the Raspberry Pi5)
1x HDMI-2 (connected to the Raspberry Pi5)

1x SO-239 TRX (connected to the Hermes Lite)
1x SO-239 ATU (connected to ATU-100-EXT)
1x SO-239 ANT (connected to ATU-100-EXT)

Note on the SO-239 sockets:

If no external PA is used, the TRX and ATU are bridged externally with an RG58 cable. To use an external PA, TRX is connected to the input of the PA and the output of the PA is connected to ATU. With this solution, the ATU-100-EXT can be used in both cases.

1x 12V DC (for external power supply)

1x 3.5 mm jack stereo (K . … currently not yet in use)
1x 3.5 mm jack stereo (C … currently not yet in use)
1x 3.5 mm jack stereo (S … currently not yet in use)

SDR Software für Raspberry Pi5

Either piHPSDR or deskHPSDR is recommended as touch-compatible SDR software to be used with the Hermes Lite 2.

Notes on the Waveshare 10.1 PCAP touch display:

The speaker header should not be used, as this leads to interference in the reception spectrum via the loudspeaker lines. The 3.5 mm audio-jack is better suited for connecting external loudspeakers with an appropriate amplifier. Note: The Raspberry PI5 itself no longer has a headphone or loudspeaker output.

The Waveshare 10.1 PCAP touch display should be supplied directly via a USB-C 5V cable.

1x BGTXINGI 5A Constant Voltage Current DC-DC Buck Power Module

Notes on 5V power supply for Raspberry Pi5:

I have changed the DC DC converter from Hailege H-1-154 to BGTXINGI. The BGTXINGI produces less HF interference and has the advantage that the output voltage can be variably adjusted.

I have also integrated DC filter boards from YOUMILE.

If you know HF-clean 5V DC/DC converter that can deliver 5A, then please send me a E-Mail :-).

An analogue voltage converter is unfortunately not an option due to the considerable heat development.
