Case Study: Starbucks Cafe achieves cost-efficient streaming player deployment with Promwad

Starbucks Cafe launches a budget-friendly smart player with Promwad using $0.08 DC-DC converters

Promwad collaborated with a European tech company to develop a cost-optimized, ARM-based smart player for commercial spaces. The challenge was to create a compact device for streaming audio/video via Ethernet, based on an Ubuntu ARM board, that was easy to manufacture in large volumes for clients like Starbucks cafe.

Promwad's solution included custom hardware design around an Amlogic SoC, extensive thermal modeling for passive cooling, and software development for board bring-up and automated testing. This resulted in a reliable, budget-friendly B2B product for the client, with its performance and thermal reliability verified through laboratory testing and simulation.
