P-PSDK Payload Expansion Board
A payload expansion board built on a domestic SoC with a 6 TOPS NPU, dual gigabit Ethernet and E-PORT integration, for onboard compute and sensor access in inspection and monitoring work.
Positioning
P-PSDK is an integration platform for adding third-party sensors and devices to an airframe. It implements E-PORT IIC authentication, exposes standard payload interfaces, and provides the compute and connectivity needed to run payload software on the aircraft rather than relying on a separate onboard computer.
It is an integration product: the board combines a domestic-processor SoC, E-PORT authentication and standard interfaces into a deployable payload platform. It is not a proprietary chip design.

Supported airframes and high-privilege functions such as video stream access depend on platform authorisation. Confirm that your airframe is supported before ordering.
What this enables
- Sensor integration — attach third-party sensors over Ethernet, USB or custom I/O without a separate onboard computer
- Onboard inference — a 6 TOPS NPU handles detection and classification at the aircraft
- Ground connectivity — dual gigabit Ethernet for high-bandwidth sensor feeds or a communication module link
- Secure data handling — authentication chip plus a reserved domestic-cryptography module bay
- Expandable compute — an M.2 slot for additional processing capacity
Typical applications
| Application | How the board is used |
|---|---|
| Infrastructure inspection | Camera or thermal payload with on-device screening before transmission |
| Environmental monitoring | Multi-sensor gathering with local preprocessing |
| Survey and mapping | High-volume image handling with ground-side transfer |
| Payload prototyping | Test payload software and interfaces before committing to an airframe |
Integration support
Payload integration usually involves more than plugging in a board. Tell us:
- the target airframe and payload interface
- the sensors to be integrated and their data rates
- whether processing runs on the board or on the ground
- the power budget and weight allowance
- the required operating temperature range
For what to confirm before integration, see payload interface and platform compatibility. For connecting payload output into your systems, see AI and enterprise system integration.
Frequently asked questions
Can the P-PSDK be configured for a specific mission?
Yes. The P-PSDK is configured to the mission rather than sold as a fixed package: payload combination, data link, power and mechanical interfaces are settled before the order, and acceptance criteria are agreed before work starts.
Under what conditions were the specifications measured?
The table gives typical-condition values. Actual figures depend on payload, wind and dispatch pattern; per-item conditions are confirmed with the project.
How are price and lead time given?
There is no published price list. Pricing follows configuration and quantity; production is scheduled against orders, and lead time is confirmed with the order.
