  Unipi 1.1 can be expanded by up to 56 relays. For this purpose is used the I²C expansion module EMO-R8, which can be purchased [[https://www.unipi.technology/cs/8-relay-addon-emo-r8-p34|in our e-shop]].
  Instructions for use with SW Mervis can be found [[en:sw:01-mervis:unipi11-with-emo-r8-hidden|here on this link]].
  
  The module can be connected using the RJ11 connection cable included in the package.
