# VT132 Bill of Materials (Draft)

Note:

The BOM is yet to be updated to include details of

  • the Stand Alone edition
  • the USB interface for USB-HID keyboard support

The parts listed below are common for both editions with the exception of:

  • the Through Hole (THT) headers supplied
  • the Printed Circuit Board (PCB)

Notes on the PCB

  • The silk screen on the Beta Kit PCBs (V1.3) is not final
  • Part identifiers are correct and there are no known errors
  • Graphic decals and label placement are not final

# Surface Mount Device (SMD) components

Don't Panic

  • Yes there are two SMD components!
  • You can do it!
  • You can do it with a regular soldering iron, but you are going to need flux
