== Technical overview ==
* 7-inch IPS panel with fixed hardware resolution of 1024×600 pixels.
* 5-point capacitive touch with toughened glass panel up to 6H hardness.
* Supported operating systems on Raspberry Pi: Raspberry Pi OS, Ubuntu, Kali, Retropie.
* Onboard RJ45 Ethernet port and USB hub functionality on the board.
* 4-pin speaker header (P2.0) and 3.5 mm audio jack; HDMI audio output is supported.
* Input voltage range: min. 4.75 V / standard 5.00 V / max. 5.25 V.
* Input current: min. 750 mA, standard 800 mA; power supply should provide at least 3000 mA, otherwise start-up failures or abnormal display may occur.
* Operating temperature range: 0–60 °C; storage temperature: -10–70 °C.
* Overall dimensions: 192.96(H) × 110.76(V) × 17.00(D) mm; weight approx. 227 g.
* Display interface: Mini HDMI; powered via 5V Type-C connector.

'''Commands and examples – verify before use:'''
<syntaxhighlight lang="text">
hdmi_force_hotplug=1
config_hdmi_boost=10
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
</syntaxhighlight>

== Notes and version constraints ==
* The config.txt lines are version-sensitive: newer Raspberry Pi OS versions may use different hdmi_cvt syntax; verify applicability before deploying on a specific system.
* Power supply must deliver at least 3000 mA; insufficient supply can cause start-up failure or permanent damage – size the power source accordingly.
* Long-term storage in high temperature/humidity environments can damage the display; store only within the stated temperature limits.
* PWM backlight adjustment requires rotating a 10K resistor by 180°; this is a physical board modification and should be done only after consulting the manufacturer.
* Disabling the backlight requires replacing the 82K resistor with a 68K resistor – also a physical modification requiring skilled execution.
* Exact pin assignments for the speaker header (left/right channel) are shown as a diagram in the original document; without the figure the assignment remains uncertain.
* Max current output of the USB host ports is 1 A; when connecting external devices, ensure total load stays below this limit.
