This is a "SparkX Carrier Board" revision v42.

Digikey IC Part: https://www.digikey.com/products/en?keywords=SP25BIOS-0042-ND

Data matrix code on the back: "There is no game"

Datasheets and what we've done with them:

SP250Ψ_DATASHEET.pdf
   Just an overview? Has content from other sheets greyed out

SP250Ψ_DATASHEET_ERRATA-AM_CSNR_(REV. A).pdf
    Indicates how to read out the serial number (?) using RF broadcast on a specific GPIO pin

SP250Ψ_DATASHEET_ERRATA-BIOS_COMPATIBILITY_(REV. A2).pdf
    USED: gave us the part number to order from Digikey

SP250Ψ_DATASHEET_ERRATA-BOOT_PROCEDURE_(REV. A).pdf
    USED: Gave us the code to boot... might use more?

SP250Ψ_DATASHEET_ERRATA-RF_CONSIDERATIONS_(REV. B).pdf
    Indicates spot to look at

SP250Ψ_DATASHEET_ERRATA-USB_ID(REV. A).pdf
    USED: told us to add a resistor, which unlocked serial USB menu

SP250Ψ_DATASHEET_ERRATA-VORTEXS_SYSTEM_(REV. A).pdf
    Indicates a specific pin ("smaller drill hole") that we can read out voltage codes using multimeter/oscilloscope. Then had a table to look up codes... but redacted. "VORTEX" codes

SP250Ψ_THERMAL_SUPPLEMENTAL.pdf
    Indicates that we should freeze the device

Other things to try/not-forget:

RC1,RC2 holes
big number we got out (96 digits)
video files and photodiode in response to "Neuromorphic Processing Unit

Failure" error message (when we get that)

"TS/SI-UMBRA" seems to be an NSA reference ("top secret, sensitive information"; UMBRA was a classification level ("most sensitive material") https://en.wikipedia.org/wiki/Sensitive_Compartmented_Information
