Development Platform , and handy kit of parts
NOTE **** All SimmSticks use a board thickness of 1.26mm, or .05 inches.
SimmStickTM is a 30 pin simm socket based Single Board Computer designed by Antti Lukats from Estonia that has started with the PIC16Cxx chips and is now migrating to other Microcontroller families such as the Atmel devices. There are now Atmel AVR and non-AVR support boards for both 20 and 40 pin micros. The simm socket used is the common 30 pin one used for many years on PC motherboards.
Small and large proto boards, CPU boards, Motherboards, and many I/O boards are under design. Custom or third party boards are encouraged. Dontronics now has many new board designs available. These include Relay modules, LEDs and Switches I/O boards, and two new motherboards.
Boards are re-usable and reconfigurable for many different applications. You can prototype a design on a breadboard with a 30 pin Simm Socket for your PIC16Cxx or Atmel micro, then a final board design can include or exclude the SimmStick module.
The best part is the price. About $6USD retail per bare printed circuit board for single quanities. This if for a 3.5" by 1" double sided, plated through, solder masked board.
The Dontronics DT001 8 slot Development Platform also contains an inexpensive PIC programmer for the SimmStick bus. A SimmStick bus structure isn't a definite requirement as these modules can also be connected together with straight or right angle 30 pin male and female pins, as a set of header pin holes are provided just behind the edge connector pads.
What are the 3 special I/O
lines used for?
Why connect D0 to D15 together
on the motherboards?
On larger applications, or
where multi-processors are used, you may need to custom design or jumper
a motherboard to suit.
If you need to design and manufacture a custom motherboard and use off the shelf SimmSticks, then future design is easy. You don't need to cut tracks and run jumpers on SimmSticks if you do all your configuration on the motherboard.
