Hardware and software design for a radio module with WLAN technology (WLAN 802.11b/g 2.4 GHz) for cordless screwdrivers. This radio module was developed by EST as part of a research and development project for a customer. Technical specifications of the module:

  • WLAN 802.11b/g 2.4 GHz
  • Multilayer
  • Up to 16 screwdrivers can be connected to a master unit
  • Each screwdriver has a unique ID (e.g. 0345001)
  • Standby mode for saving battery capacity
  • Integrated interfaces: Barcode scanner, display, acoustic signaling device
  • Temporary storage of data on the radio module if no radio connection exists (for example, for screw driving operations in the interior of a vehicle ("Faraday cage"))
  • Battery change without data loss
  • Central parameterization and vizualization
