 # Approaches
 
 ## Smoothieware Port
+
 The Charmhigh conversion undertaken by others approaches leaving the controller largely intact
 and flashing a Smoothieware port onto the STM32. The repo notes suggest the Charmhigh used an
 STM32F4, which the TM245P also uses. Specifcally the STM32F407ZGT6.

 ## 'Decap'
 In this approach the entire head unit will be bypassed. Ideally this could be accomplished by
 utilizing the existing IDC connector on the power/comm sub-board.
