Arduino Yún: Arduino With A Wifi System-on-a-chip

blog.arduino.cc:

Arduino Yún is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331, a system on a chip running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices.

Available at the end of June for $69.

 
Arduino Yun Specifications (via cnx-software.com):
  • MCU – Atmel ATMega32u4 @ 16 MHz (same as the one used in Leonardo board) with 2.5KB SRAM and 32KB flash

  • SoC – Atheros AR9331 MIPS-based Wi-Fi SoC running Linino, Arduino’s own Linux distribution based on OpenWRT. It’s the same chipset as in TP-Link WR703N router.

  • Storage – microSD card slot

  • USB – micro USB connector + full USB host port

  • Connectivity – Ethernet + Wi-Fi

  • 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs)

maxon motor's - Exoskeleton Joint Actuator

A brushless DC motor solution for use in hip and knee exoskeletons. This complete joint actuation unit consists of motor, gearhead, encoder and position controller. Fitting absolute encoder directly at the joint rotation provides designers increased positioning accuracy. The unit will deliver 54Nm of continuous torque and 120Nm on a 20% duty cycle. The system can be operated on supplies between 10 and 50V DC and the actuation speed is up to 22rpm.
