M128B-TERM Price: $159 Qty: 16.000 MHz 14.7456 MHz	M128B, Assembled and Tested, Screw Terminals MAVRIC board assembled and tested with .1 inch screw terminals installed. The screw terminals are the ideal general purpose connectors, making interfacing to the outside world a snap. NOTE: Not recommended for new designs. Please see our MAVRIC-IB instead.
M128B-ASSM Price: $119 Qty: 16.000 MHz 14.7456 MHz	M128B, Assembled and Tested, Standard Headers Basic M128B board, assembled and tested, with standard pin headers (not installed). The pin headers are not installed because some folks like the headers pointing up, some like them to point down, and some like to install a different kind of header completely, for example, sockets instead of pins.

M128B-KIT Price: $74 Qty: 16.000 MHz 14.7456 MHz	M128B, Kit The Kit includes the MAVRIC PCB and all the parts needed to fully populate the board. This is a great option if you are skilled at soldering and circuit assembly, but you don't have all the parts on hand and don't wish to order them yourself. This includes all the parts shown in the photograph. A soldering tutorial is available. NOTE: Not recommended for new designs. Please see our MAVRIC-IB instead.
M128B-PCB Price: $14 Qty:	M128B, Bare PCB The Bare PCB is just the bare printed circuit board with no components and no assembly. The PCB is a high quality, silk-screened and solder-masked circuit board, professionally manufactured for ease of soldering and usability. This is the most cost effective option if your parts cabinet is reasonably well stocked and you are skilled in soldering and circuit assembly. A complete parts list is provided with your board. A soldering tutorial is also available. NOTE: Not recommended for new designs. Please see our MAVRIC-IB instead.
