Name that Ware, September 2024

The Ware for September 2024 is shown below:

This ware was a gift, but I won’t credit the donor until the solution is revealed, because the credit itself might give a clue about the ware.

My first reaction to seeing this board is: “this thing has a high BOM cost”. My second thought is the engineers who put it together (hopefully) got a lot of free lunches and design advice from US-based FAEs (been there, done that!). My third reaction is, huh, this is a thing (link goes to a Digikey listing for the tiniest photointerrupter that I have ever seen – 2.26 x 1.4 x 1.6mm – it’s ISO1 and ISO2 in the first image of the board; they are flanking the top and bottom of the rectangular cut-out in the board. Could come in handy someday, especially with the compact electromechanics of IRIS…).

    I’ll go first:

    I’d say it is a (personal or stationary) gas detector/monitor e.g. measuring CO / VOC gas concentrations.
    Giveaway is the LMP91000 sensor frontend + supporting circuitry.
    Some battery chips from TI, power supply/charging via USB-C, Bluetooth SoC for wireless readout. Topped off with some LED drivers for an UI on the device.
    Given some analog switching logic (ADG704), it might even be a multichannel sensor monitor, muxing the sensors one by one to the LMP91000.

    As for the photo-interrupter: ATEX-safe push buttons? Since a conventional push button might cause a mini spark and are usually a no-go in ATEX situations.
    That would also explain the efforts taken on the BMS part of this device (and why BOM is less of an issue).

    Guessing a brand: Riken Keiki?

    Looks like a Microsoft SurfLink connector on the upper-right.

    Automated insulin pump, maybe?
