The Spectrum V1 OSD Module from Ukrainian manufacturer ITL Spectrum, presented under the dronehub brand, is a compact plug-and-play OSD device for FPV drones, surveillance cameras, and other video systems. The module comes with a pre-flashed STM32G030F6P6 (Cortex-M0+) microcontroller and ensures quick integration via the USART interface. The device is designed and manufactured in Ukraine with quality control at all stages of production.
Purpose and Main Functions
The OSD module is designed for overlaying text and graphic information onto analog video in real time. Thanks to dynamic drawing support, inscriptions and graphics can be changed during flight using an internal or external microcontroller. The module allows displaying telemetry, system messages, graphic symbols, background fill, ballistic sights, and other useful elements on the video signal.

Connection and Interfaces
The module has two groups of pins: left (technical) and right (main). The left cable is used for programming and 3.3V power connection, the right for data exchange and video signal operation. For module operation, an internal microcontroller or an external MCU can be used according to the protocol described in the documentation.
Left Cable (Technical)
| Pin | Purpose |
|---|---|
| 1. GND | ground |
| 2. SWLCK | clock signal for programming |
| 3. SWDIO | data line for programming |
| 4. +3.3V | 3.3 V power supply |
Right Cable (Main)
| Pin | Purpose |
|---|---|
| 1. Video out | video output with overlaid image |
| 2. Video in | analog video input, over which OSD is formed |
| 3. GND | ground |
| 4. Tx | USART data transmission (to Rx of external microcontroller) |
| 5. Rx | USART data reception (to Tx of external microcontroller) |
| 6. +5V | 5 V power supply |
Module Advantages
| Advantage | Description |
|---|---|
| Dynamic Drawing | Text or drawings can be changed during flight using an external microprocessor |
| Ready Firmware | Ready firmware and communication protocol for easy integration and low entry barrier |
Usage Examples
| Application | Description |
|---|---|
| Ballistic Sight | Ability to draw a ballistic sight for precise targeting |
| Drop Module Telemetry | Display real-time telemetry of the drop module |
Application: This OSD module is ideal for FPV drones, surveillance cameras, and other video systems where real-time overlay of text and graphic information on the video signal is required.
Recommendation: For full functionality, the microcontroller on the board (STM32) needs to be programmed or an external MCU connected, using the protocol described in the module documentation.
