Microchip shows a “smart transport” concept where many small sensor/actuator nodes speak Bluetooth Low Energy and a gateway (here, a phone) collects telemetry and control in real time, reducing long wire runs while keeping a familiar “vehicle sensor network” mental model for embedded developers. https://www.microchip.com/en-us/product/pic32wm-bz6204ue

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

In the demo, each board behaves like a subsystem: a CAN-connected cluster, touch input driving a motor function, a temperature-driven fan loop, and a solar-panel node where shining a phone flashlight visibly changes the measured voltage. The interesting part is the full path: sensor → BLE link → gateway UI, plus bidirectional control back to the edge device in the same session for tight feedback.
The platform callout is the PIC32-BZ6 family (also available as RF-certified modules): a 128 MHz Arm Cortex-M4F MCU with FPU, 2 MB Flash and roughly 512 KB SRAM, aimed at leaving headroom for OTA firmware growth while hosting multiprotocol stacks like Bluetooth LE and IEEE 802.15.4 (Thread, Matter, and proprietary options). Pairing that with “real” MCU peripherals such as CAN-FD and typical ADC/PWM/touch blocks is what lets one design bridge legacy bus traffic with app-driven wireless control today.
Filmed at Embedded World North America 2025, it’s a practical snapshot of how embedded teams mix deterministic CAN-style domains with BLE and 802.15.4 ecosystems, aiming for simpler harnessing, easier provisioning, and smartphone-first diagnostics while keeping the real-time loop close to the device for predictable edge behavior here.
