= Hardware Revisions =
== DSi ==
** board C/TWL-CPU-01 (Original rev, all pictures below)
** CPU: TWL. The latest date code picture I could find online was "0836 1m" as shown below, however other pictures with CPU covered show the NAND codes as late as 916, so...
** Suspect this is the only board where WiFi chip is available in Hybrid games like CookingCoach
** Wireless card DWM-W015
== DSi RevA ==
** board C/TWL-CPU-10 (Newer model, can someone provide a date or serial # range?)
** CPU: TWL A. Mine is "0940 2m". My US Serial # is ~ TW71848???[5]. If yours is earlier, please update this.

== DSi XL ==
** board C/UTL-CPU-01
** CPU is TWL A
** Wireless card DWM-W024
