+# 3DR Control N1 Flight Controller
+
+<Badge type="tip" text="PX4 v1.18" /> 
+
+::: warning
+PX4 does not manufacture this (or any) autopilot.
+Contact [3DR](https://3dr.com/) for hardware support or compliance issues.
+:::
+
+The _3DR Control N1_ is a compact, high-performance, low-profile and lightweight flight controller designed and assembled in USA.
+It runs PX4 on the [NuttX](https://nuttx.apache.org/) OS.
+
+![3DR Control N1](../../assets/flight_controller/3dr_ctrl-n1/3dr_ctrl-n1.jpg)
+
+::: info
+This flight controller is [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).
+:::
+
+::: tip
+This flight controller requires a carrier board to work correctly, visit [3DR](https://3dr.com/) for more information.
+:::
+

+
+## Building Firmware
+
+::: tip
+Most users will not need to build this firmware!
+It is pre-built and automatically installed by _QGroundControl_ when appropriate hardware is connected.
+:::
+
+To [build PX4](../dev_setup/building_px4.md) for this target:
+
+```sh
+make 3dr_ctrl-n1_default
+```
+
+## Connectors
+
+The Control N1 uses three Hirose DF40-series board-to-board connectors:
+
+| Connector | Pins | Signals                                                |
+| --------- | ---- | ------------------------------------------------------ |
+| J100      | 30   | USART1, USART2, USART3, UART4, SDMMC, USB              |
+| J200      | 30   | USART6, FDCAN1, SPI, SWD, miscellaneous                |
+| J300      | 80   | UART7, UART8, FDCAN2, I2C, ADC, Motor outputs CH1–CH12 |
+
+For more information about the pinout, visit [3DR Control N1 Pinout Tool](https://docs.3dr.com/autopilots/control-n1/#pinout).
+
+## Serial Port Mapping
+
+| Port | Connector | Peripheral | Flow Control | Default Function |
+| ---- | --------- | ---------- | ------------ | ---------------- |
+| SG1  | J100      | USART2     | Yes          | TELEM1           |
+| SG2  | J100      | UART4      | Yes          | TELEM2           |
+| SG3  | J300      | UART7      | Yes          | User             |
+| SG4  | J100      | USART3     | No           | GPS2             |
+| SG5  | J100      | USART1     | No           | User             |
+| SG6  | J200      | USART6     | No           | RC input         |
+| SG7  | J300      | UART8      | No           | GPS              |
+
+## Debug Port
+
+The [SWD debug port](../debug/swd_debug.md) is exposed on connector **J200**.
+A BOOT0 pin is also available on the same connector for firmware recovery.
