I have a question pending with @@simpleavr if the calc buttons must be white or black. Not sure what the original color was.

 

All the ones I made were w/ white buttons. Just matches well w/ the white silkscreen on the green PCB. As long as they are two pin 6.5mm spaced they are good.

 

I pick the green PCB as when I started the project Elecrow has this 5x10cm green pcb for $11.90. Now they are offering any color for $12.90, so I cannot resist and have to make this.....

@@simpleavr I'll have white PCBs made :) Good call.

 

@@cubeberg I have one too. I'll use the LP in this case. Since they are not too many. If I make you do it, we'll have to ship the chips around.

 

Edit: Going with green for this batch.

 

I also prefer green for the TMS080x emulation.

 

The white PCB is actually for another emulator (WIP).

Update:

Hi All.. thank for waiting patiently. All parts are in. I've been spending the past few days with Chris @@simpleavr on an issue I had( wanted to make sure the board was good ). Please expect shipping in the next couple of days through next week.

 

If anyone who ordered wants me to solder and test one up for you, I can do it for $10. But let me know in the next day or so.

 

Thanks for participating in this group buy. 

I'll see if I can carry it in the Store. If possible please spread the word!

 

The one I have has a socket in place to test your programmed MSP430s

I would recommend this for those who are not regular builders. I had designed this to be all thru-hole to accommodate most builders. But if you haven't touch a soldering iron for years it could still be challenging.

 

My first build takes took two hours (consider that I design the thing and had breadboarded it already) and one full day of debugging. I am sure it goes the same for blue#.

 

Thanks blue# for sending a board over for verification. It's a good move as the board is a little bit "newer" than mine.

 

/EDIT correct engrish
