Overview
The VEXpro ARM9 Microcontroller is a redesign of the popular Qwerk microcontroller as a result of a collaboration between VEX and Charmed Labs. The ARM9 Microcontroller is designed to be used by advanced users.
The ARM9 Microcontroller uses standard 802.11b/g communication. This will allow (with programming) highly configurable communication to PC's and wireless networks. The Carnegie Mellon Telepresence Robot Kit (TeRK) project provides a powerful feature to the ARM9 Microcontroller allowing robot control and video feedback across the internet. The controller can be operated from PC and Linux machines.
The VEXpro ARM9 Microcontroller requires a 7.2V Robot Battery, a VEXnet USB Adapter Key and a PC running Windows or Linux.
A USB A to mini B cable (sold separately) is required to configure Wifi encryption and to update firmware.
