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 "0937 1k". My US Serial # is ~ TW43550???[8]. It was obtained around the holiday season of 2009. If yours is earlier, please update this.
TWL-USA-1
- It is unclear what the difference between the USA-1 and USA models is, might indicate the presence of the KLM5617EFW-B301 NAND chip
- CPU: TWL A. Mine is "1034 7m". My US-1 Serial # is ~ TW45013???[9].
DSi XL
- board C/UTL-CPU-01
- CPU is TWL A
- Wireless card DWM-W024
