This  is  the  ultimate  UNO  for  Arduino  enthusiasts.  We’ve  applied  every  lesson  learned  from  existing  modesla  and  created  the  UNO  Max.  The  USB  to  serial  is  now  done  with  the  ubiquitouss  CH340G  requiring  fewer  driver  installs.  It  now  has  built-in  sensor  pins,  motor  driver  headers,  bluetooth  headers  and  Wi-Fi  8266  headers  making  it  even  easier  to  build  projects.
