We provide two packaging options for the Wio-E5-LE module, differing mainly in the number of packages. Please choose the version that best aligns with your requirements.

  • This one is the Tape Reel version, it is recommended for automated SMT assembly, as it comes in reel form. Please note that if you select the Tape Reel version and quantities less than 1000 pieces will be sent in cut tape form and quantities of 1000 pieces or more will be sent on reels of 1000 pieces, with the remainder sent in tape form.
  • Another version is the Bulk version, the modules are packaged individually, and we can deliver any quantity of modules in bulk. Please note that there is a potential moisture risk with this separate packaging option.
