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)
- serial/SPI data on "middle of 3" GPIO pin; ~38kHz periodicity, ~5MHz bit rate, 16 bit words sometimes double or more (32bit), based on terminal status (but continuous)
"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
