Vocera B1000A teardown

[Gray] over at Geek Chique had a bit of an eBay mishap and was suddenly the proud owner of 16 Vocera B1000A badges. If you are not familiar, these badges are small, lightweight communications devices similar to the famous Star Trek communicator, which allow users to talk to other individuals via VOIP. He was working on getting the remaining badges up and running by reimplementing the server software, and figured that since one of the badges he purchased was not working, he might as well take it apart.

It took him awhile to get the well-made badges apart, requiring a rotary tool and some elbow grease to get the job done. Inside, he found that the device was split into two circuit boards, one being the “WiFi” board, and the other the “CPU” board. The WiFi board uses a Prism WiFi chipset, which was incredibly common at the time of construction. The CPU board sports small SRAM and flash chips as you would expect, with a Texas Instruments 5490A DSP running the show.

While it remains to be seen if tearing the device down helps [Gray] to get things up and running again, it never hurts to take a closer look to see what you are working with.
