SSC30KQ + IMX335 Camera
SSC30KQ is a budget single-core SoC from SigmaStar — essentially a cut-down SSC338Q (1 core instead of 2). Paired with the 5 MP Sony IMX335 sensor, it became one of the most popular options for light and cheap OpenIPC FPV cameras: a ready-made module (e.g. Anjoy MCL12 / L12B) costs around $11.
Thanks to its low power draw and small weight, the SSC30KQ is a great fit for compact drones, whoops and 4G/LTE builds (QuadroFleet). The bigger SSC338Q handles 4K and peak performance, while the SSC30KQ is all about minimum cost and weight.
In short
- Cheap (~$11 for a ready module) and light — for small builds
- The IMX335 sensor does up to 1080p@60 and even 720p@120 for smooth video
- Latency around 80 ms (1080p@60) and 60 ms (720p@60)
Specifications
| Parameter | Value |
|---|---|
| SoC | SigmaStar SSC30KQ, ARM Cortex-A7 (1 core) |
| Sensor | Sony IMX335, 1/2.8″, 5 MP, Starlight (low-light) |
| Encoding | H.265 / H.264, audio embedded in the stream |
| Bitrate (FPV) | from ~15 Mbit/s H.265 (depends on settings) |
| Latency | ~80 ms (1080p@60), ~60 ms (720p@60) |
| Network | Ethernet 100 Mbps |
| Wi-Fi | via external USB adapter (network cards) |
| Flash | NOR 8/16 MB or NAND (depending on version) |
| Power | DC 5V or 12V (board-dependent) |
| OpenIPC support | Yes (FPV, Majestic, WFB-NG) |
IMX335 video modes
The IMX335 driver in OpenIPC supports several modes — trade resolution for smoothness:
| Resolution | Frame rate | Use case |
|---|---|---|
| 1920×1080 | 60 fps | maximum detail |
| 1600×904 | 80 fps | balance of clarity and smoothness |
| 1424×800 | 100 fps | fast flying |
| 1280×720 | 120 fps | maximum smoothness, racing |
Higher FPS = lower latency
For dynamic flight, 720p@120 feels much "crisper" than 1080p@60, even though the resolution is lower.
Connector pinout
Typical connector pinout of an OpenIPC IP camera (verify against the markings of your exact board):
| Group | Contacts |
|---|---|
| LAN / Ethernet | TX+ (1), TX− (2), RX+ (3), RX− (6) |
| Power | GND, +12V |
| Audio | GND, In, Out |
| Alarm | GND, In |
| LEDs | Green+, Amber+ |
| Other | IRC (IR-cut), D/N (day/night) |
Before flashing
Flashing needs the UART (RX / TX / GND) contacts. On many SSC30KQ boards these are exposed as separate pads — locate them by the RX/TX/GND markings.
How to flash OpenIPC firmware
- Download the firmware for SSC30KQ from the OpenIPC builder releases — look for files like
openipc.ssc30kq-nor-fpv.tgz(for NOR flash) or...-nand-...(for NAND). - Flash the camera one of two ways:
- over UART — see the detailed UART flashing guide;
- or with the Multiconfigurator (easier).
- For the APFPV firmware (direct Wi-Fi, no ground station) see the APFPV guide.
Caution
Do not cut power during flashing — it can brick the camera.

| For | light and budget builds | maximum quality |
➡️ If you want it light and cheap — SSC30KQ. If you want the best image — SSC338Q + IMX415.
