I usually consider myself lucky if it’s possible to identify one or two of the chips on the board, especially if they’re the important ones.

In this series of teardowns, we’re often confronted with some unfortunate realities, such as the fact that epoxy blobs and unmarked ICs are so common these days that it’s nearly the norm. But since the STM32F217VGT6 already has fairly ample onboard flash, it seems more likely it’s being used to hold configuration data.

Next to the MCU is a 16 Mb AT45DB161D serial flash chip, which under normal circumstances I would assume held the chip’s firmware. It’s not immediately clear why such a powerful chip is necessary to facilitate communications between the main PCB and the HE863-NAR, though its hardware accelerated encryption capabilities are potentially being put to use. The STM32F217VGT6 packs a 120 MHz ARM Cortex-M3 CPU and an impressive array of capabilities, including built-in Ethernet and USB.
I didn’t expect there to be much else interesting on the 3G2075, but pulling open the RF shield revealed an unexpectedly large microcontroller. Our particular specimen has been robbed of its backup power, so you’ll have to use your imagination.Īs we can see the cellular communications board features a SIM slot (with an unpopulated spot for a second), an external antenna, and an HE863-NAR 3G module that’s capable of pulling a respectable 7.2 Mbps over HSPA and features voice and SMS support. Or, at least, there should be a battery in the rear compartment. The SCW9057G-433 comes apart in two pieces with a bit of coercion around the edges, with the battery and 3G2075 “Alarm Communicator” board on the rear and the main PCB on the front. If it’s possible to put together your own homebrew alarm system with one of these units at the core, then it seems the least we can do is take it apart and see what kind of potentially modifiable goodies are waiting under that shiny plastic exterior.

The extensive documentation from Impassa covers how to wire and configure the device, and as long as the system isn’t locked when you get it, it seems like wiping the configuration and starting from scratch isn’t a problem.
The alarm can connect to a wide array of 433 MHz devices.įrom how many of these are on eBay, and the research I’ve done on some home alarm system forums, it appears that you can actually pick one of these up on the second-hand market and spin your own whole-house alarm system without going through a monitoring company like ADT. As you might have guessed from the model number, this unit uses 433 MHz to communicate with various sensors and devices throughout the home, and also includes a 3G cellular connection that allows it to contact the alarm monitoring service even if the phone line has been cut. Of course it also means I can’t be blamed if you don’t like it, so keep that in mind as well.Ĭoming our way from the tropical paradise of Eastern Pennsylvania, this month’s subject is an ADT branded Impassa SCW9057G-433 alarm system that was apparently pulled off the wall when our kind patron was moving house. Which is why I’m always so thankful when a reader actually sends something in that they’d like to see taken apart, as it absolves me from having to make the decision myself. But in truth, finding a new and interesting gadget every month can sometimes be a chore.
This series of monthly teardowns was started in early 2018 as an experiment, and since you fine folks keep reading them, I keep making them.
