See Projects

The WunderBar by relayr is a revolutionary IoT (Internet of Things) starter kit that includes six different sensors and a master module. This kit enables hardware and software developers to quickly and easily prototype their ideas and create apps to interact with the physical world. The kit works right out of the box and is energy efficient, fast, and secure.

Master Module

  • Freescale ARM Cortex-M4 MK24
  • 1MB Flash, 256KB SRAM
  • 12 GPIOs (analog, SPI, I2C, UART)
  • Gainspan GS1500 WiFi with TLS encryption
  • Nordic nRF51822 with Bluetooth LE stack
  • Li-ion Battery charger
  • USB-OTG
  • Device firmware upgrade over USB (for BLE, Kinetis & WiFi module)
  • Backup Li-ion battery included

Mini Modules

  • Dimensions: 18.6 x 29 x 6.8 mm
  • Nordic ARM Cortex M0 nRF51822
  • Bluetooth LE stack, ceramic antenna
  • 256KB flash, 16KB SRAM
  • 8 GPIOs (analog, SPI, I2C, UART)
  • 1 x WiFi
  • 1 x BLE bridge to Grove/Arduino/Raspberry Pi
  • 1 x IR transmitter
  • 6 x BLE (Beacons)
  • 8 x Sensing variables
  • 3V CR2032 Lithium batteries included
  • Over the air firmware upgrade (from onboarding app)
  • All modules have 8 exposed pins (can be used as GPIOs, I2C, UART, PWM or analog inputs)
