Firmware updates add features, fix bugs, and improve measurement accuracy. The NanoVNA-F V3 uses a simple USB file-copy method -- no special flashing software is required.
|
|
|
|
## Download the firmware
|
|
|
|
<Steps>
|
|
1. Visit the official firmware page at [sysjoint.com](https://www.sysjoint.com).
|
|
2. Locate the latest firmware file for the NanoVNA-F V3.
|
|
3. Download the file. It will be named **`update.bin`**.

## Copy the firmware file
|
|
|
|
<Steps>
|
|
1. Open the USB drive on your computer.
|
|
2. Copy the **`update.bin`** file to the root of the USB drive.

<Aside type="caution">
|
|
Do not disconnect the USB cable or power off the device while the file is being copied. Interrupting the transfer can leave the device in an unusable state.

## Apply the update
|
|
|
|
<Steps>
|
|
1. Disconnect the USB cable.
|
|
2. Power off the NanoVNA-F V3.
|
|
3. Power it back on normally (without holding any buttons).
|
|
4. The device detects `update.bin` and applies the firmware update automatically.
|
|
5. The update process takes a few seconds. The device restarts when finished.

<Aside type="tip">
|
|
After a firmware update, it is good practice to recalibrate the device. Some firmware updates may alter calibration behavior or add new calibration features.
|

|
|
The `update.bin` file is automatically deleted from the device storage after the update completes. You do not need to remove it manually.
