/ 01 — CONNECTIVITY

Flight Controller Pinout and Connectivity Overview.

FLIGHT CONTROLLER · PINOUT OVERVIEW
NAS flight controller pinout diagram — top and bottom board views with UART, GPIO, ELRS, I2C, camera, ESC and power connections labelled
6 × UART

Six UART (Universal Asynchronous Receiver/Transmitter) interfaces, providing extensive flexibility for external device connectivity.

2 × GPIO

Two GPIO (General-Purpose Input/Output) pins on the drone stack, configurable to the desired application or user requirements.

SSD

Solid-State Drive — an internal high-speed electronic storage drive.

ELRS

With ELRS, the stack provides an ultra-fast, highly reliable, long-range and lightweight control link between the drone and the remote controller.

I2C

I2C increases flexibility and enables communication with external components such as compasses, GPS modules, LiDAR/sonar systems, weapons systems, etc.

NDAA Compliant

A US standard that sets a high bar — also within NATO. This equipment complies with the US National Defense Authorization Act, meaning it contains no components, chips or software from selected sanctioned Chinese manufacturers (such as Huawei, Hikvision or Dahua), ensuring a high level of cybersecurity. Although it is US law, NDAA compliance functions today as an international security standard — many partners and defence organisations in NATO countries, including Denmark, require it.

/ 02 — ESC

The muscle behind the stack

ESC · PINOUT OVERVIEW

[ FC + ESC ]

Combined with the NAS Flight Controller (FC), this ESC provides complete situational awareness, precise control, and exceptional stability in flight — even under the harshest conditions. Together, they form a combination that is second to none.

Agility

This ESC is engineered for rapid maneuvering, seamless response to a wide range of control inputs, and outstanding flight stability.

Power

Engineered for high-current and high-voltage operation, this ESC reliably handles even the most demanding control inputs and flight conditions.

Flexibility

For maximum flexibility and adaptability, the ESC supports both 4S and 6S batteries.
