DT007 is a small motherboard primary made for Atmel SimmStick boards from Dontronics and LAWICEL and the Stamp Stick boards from Wirz.
|COMPONENT PART LIST|
|LD5||3mm green LED|
|LD6||3mm red LED|
|K1||2.1mm power or screw terminal|
|K2||IDC10 for Kanda/STK200 programming interface|
|K3||RS232 DB9/Female connector|
|J1/J2||Insert these jumpers for StampStick 2SX|
|SIMM1||Dual SimmStick connector|
The dual SIMM socket of the DT007 doesn't provide enough room to mount 2 populated cards together. It also doesn't provide the row of holes for a R/A header strip that could allow the DT205 to butt up to it. I ended up running some wires (GND, PWR, +5V, D0-D3) from the SIM100 to the DT205 to get it working. However I realised after the fact that there are several options were available. Instead of the dual SIMM socket I could use a straight header strip in the front position for the SIMM100, and a R/A header strip in the rear to allow the DT205 to butt up against the motherboard. Alternatively I could have built the SIMM100 much flatter so that it could plug into the read SIMM socket, but omiting the 10 pin box headers, jumper blocks, LEDs, chip sockets, and bending some passive components over flat.
I would appreciate a little note on the DT007 page to tell customers about this glitch and the possible options, instead of just diving in and building the things like I did :-)
Hi John, thanks for the feedback. It was never invisaged that you could put two cards into a dual simm socket.There is possibly a lot more info at http://www.dontronics.com/ssinfo.html, but I know it can be hard to find it all, and put it all together.
However, I'll put a little note on the dt007 page regarding your
in the hope that it will assist others.
