Ambarella-Based AI Vision Modules for Seamless Integration
Promwad provides the right building blocks to create your next-gen edge AI camera solutions. Our system-on-modules (SoM) are based on Ambarella processors H22, H32, CV22, and CV25.
Ambarella processors are the best choice, as they are known for low-power architecture combined with industry-leading AVC/HEVC encoding, suitable for various Edge AI applications.






Working With You from MVP to Production
Are you going to build an Edge AI vision system but are unsure if you have the proper experience and have anticipated all the pitfalls? Promwad’s engineering team is dedicated to implementing the following tasks for you:
- Help select the right components and kick off your concept with our Ambarella-based SoM ecosystem.
- Assist with requirements elaboration, provide project budgeting estimates, and perform a feasibility study in the early stages of the project.
- Execute your project from design to mass production.
- Manufacture your products at a verified and state-of-the-art production site (EMS).
