diff: # RespiraWorks Ventilator Mainboard Rev 1.0
  ## Important Rev 1.0 PCB Errata
  -* #63: DNP resistors populated on board, typing 3.3V to the 5V rail (bad) - if you have SN 01, 02, 03, or 05 - don't continue using the board without executing the fix in this issue ticket. See ticket for rework instructions and photos. All other serial number boards are shipping with this issue fixed.
  -* #64: Yellow and Green alarm LEDs don't work due to a pin use conflict on the nucleo
  -* #56: Blower command is 5V but nucleo outputs 3.3V. All boards are currently shipping with a level translator fitted which addresses this problem, however the blower will turn on full blast briefly at reset (#62 - to be fixed in next rev)
