ZYRO A7
7.1–8.2 GHz 3W Transmitter Module
ZYRO A7 is a high-power analog video transmitter for professional FPV, UAV, robotics, and long-range field video links. Its 7.1–8.2 GHz operating range, 64 channel presets, adjustable transmit power, active cooling, and IRC Tramp control provide flexible integration for demanding airborne and mobile platforms.
Built for your integration
A closer look.
7.1–8.2 GHz Coverage
Provides 64 channel presets across eight band groups for flexible frequency planning within the 7110–8210 MHz operating range.
Adjustable Transmit Power
Switch between PIT mode, 25 mW, 1 W, 2 W, and 3 W to balance range, heat, and local operating requirements.
Active Thermal Protection
Aluminum heatsink enclosure and cooling fan automatically reduce power above 100°C and restore it at 95°C.
Wide Voltage Input
Supports 8–36 V DC input and 2S–8S Li-ion/Li-Po power systems for integration with a broad range of platforms.
IRC Tramp Control
Configure operating frequency and power through compatible flight-control systems or the onboard CH/BAND and PWR buttons.
Compact 20 mm Mounting
Uses a 20 × 20 mm mounting pattern with 2.0 mm holes, SMA female antenna connector, and a total weight of 56 g.

Operation
Operation Guide
| Control | Description |
|---|---|
| Channel selection | Short-press CH/BAND to cycle through channels 1–8; the red LED indicates the selected channel. |
| Band selection | Hold CH/BAND for 5 seconds to cycle through bands A, B, E, F, R, P, H, and U; the blue LED indicates the selected band. |
| Power selection | Short-press PWR to cycle through 25 mW, 1 W, 2 W, and 3 W; the green LED indicates the selected level. |
| PIT mode | Hold PWR for 3 seconds to enter PIT mode; the green LED remains steadily illuminated. |
| Thermal protection | Output power steps down while temperature remains above 100°C and returns to the selected level at 95°C or below. |
Installation Notes
▸Always connect a matching antenna before applying power. ▸Leave adequate clearance around the fan and heatsink for airflow. ▸Verify supply voltage and polarity before powering the module. ▸Avoid sharply bending antenna and power cables. ▸Set transmitter and receiver to the same supported frequency before operation. ▸Operate only in frequencies and power levels permitted by local regulations.Applications
