 HardwareDDC features an ESP32 with reset and boot buttons, an HDMI connector exposing GND, SDA and SCL, and it's powered by USB-C which also exposes the UART console. Optionally, it can be powered by 5V directly through the GPIO pins, and additional GPIO pins are available for debugging and future expandability.

+# Hardware
+
+HardwareDDC comes with an optional two-part 3D-printed case which you can re-print yourself.

+## Print settings:
+
+_it doesn't matter that much, but it's what I used_
+
+- Layer height: 0.2mm
+- Extrusion width: 0.4mm
+- Infill: 20%
+- Walls: 4
+- Top/bottom layers: 5
+- No supports
+- Material: Board gets warm so I used ABS, but PLA should work
+
+## Assembly:
+
+### Step 1: Add Heatset Inserts
+
+- 4 x Heat Set Insert

+- 2 x M3x6 BHCS
