## Description

DroneCore Suite x G-Hadron Adapter is a combination of hardware and software for seamless transmission of the video stream from the G-Hadron gimbal into the Jetson running on the DroneCore Suite. This unit will allow the connection of the Gremsy Hadron gimbal to the DCS2 ecosystem via standardised DCS2.Payload connector

**Box content**

* 1x G-Hadron Adapter for DCS, including a software driver.
* 1x Cam – FPC cable (length 10 cm / 20 cm / 25 cm)

## Power supply

{% hint style="danger" %}
**WARNING - Do not exceed the maximum input voltage**

Exceeding the maximum input voltage of 100 V may result in permanent damage to the device. Ensure that the input voltage remains within the specified limits at all times. Special care has to be taken if voltage transients and oscillations are present, as these may cause the maximum rating to be exceeded. This can occur in systems with high inductance, during switching events, or when using motor controllers with active braking. Appropriate suppression and protection measures must be implemented.
{% endhint %}

{% hint style="danger" %}
**WARNING - Beware of excess heat**

Heat is generated by all onboard voltage regulators during operation, with dissipation increasing at higher load current and total power consumption. Adequate thermal management, such as airflow or passive cooling, is recommended when operating the board at higher load conditions to ensure proper thermal performance and prevent overheating. Onboard power monitoring can be used to provide a precise overview of power consumption across the whole system.
{% endhint %}

**Recommended Input Voltage Range:** 20–80 V

**Maximum Input Voltage:** 100 V
