After releasing E430M2 (4.3" Rugged PDA), Winmate designed the successive 3.5" version of rugged PDA, C350M2, which runs Android 4.1. The C350M2 model actually represents the second generation of the platform. A 1GHz dual-core Cortex A9 processor has replaced the TI DM3730 chip of the original version. Users now get 4GB of storage via micro SD card (and optionally up to 32GB). Onboard WiFi has been upgraded to 802.11 a/b/g/n for maximum wireless communication. Most importantly, the new C350M2 is based on Android 4.1 ("Jelly Bean"), which offers full dual-core support as well as numerous technical improvements over Android 2.3.4 ("Ginger Bread") used in the older version.
