Explanation  of  the  driver  version:  Recently,  many  customers  have  asked  about  the  difference  between  the  driver  versions.  In  order  to  mislead  customers,  many  manufacturers  write  the  driver  silk··screen  version  very  high.  

In  fact,  the  product  design  may  still  be  the  old  version.  The  Lerdge  driver  is  independently  designed  strictly  according  to  the  chip  design  manual,  and  already  has  the  perfect  function  of  the  chip.  

For  example,  the  TMC2209  module  produced  by  other  companies  according  to  the  open  source  drawing  requires  an  external  1K  resistor  when  using  the  UARNT  function.  The  TMC2209  of  LERDGE  has  integrated  the  resistor  on  the  module,  and  the  user  only  needs  to  wire  it.
