I have been working on a breadboard compatible Launchpad-based board for the DIP value-line MSP430s. I have finished an initial design in KiCAD, and am wondering if there is enough interest in this product before I get any PCBs fabricated, and to gauge how many I should produce. The main focus is to make MSP430G2 launchpad - like board that eases prototyping on a solderless breadboard, making small robotics platforms, etc. I originally designed this because I rarely use the Launchpad + boosterpack scheme, but instead usually use a value-line DIP ic on a breadboard and use the Launchpad's SBW to program them. This board will remove the breadboard setup step and let you get prototyping with some extra space on your breadboard! for a pcb + parts, my goal is around $7-8 and for bare pcb $3-5. For the option with parts, a MSP430G2452 will be the default ic to keep costs down, but if there is enough demand and I can make more, then the MSP430G2553 may be reasonable. here is a picture of a 3D render in KiCAD ( note missing push-buttons in the render ): This is only the second PCB I have ever designed, so there could be some improvement needed. Not sure if back GND plane or front Vcc plane are necessary. The back GND plane makes the most sense. Another product / accessory for this board is a small [LP2950-33] based 100mA 3.3V LDO board for breadboard power. It only has a 380mV dropout, so it can be used with 3.7V Li-ion/Li-poly batteries, so I will include a JST-PH receptacle for attaching them ( it is the connector that adafruit's li-polys use ). cost will be around $1-2 for bare pcb and around $2-3 for pcb and parts. here is a 3D render (note missing input header and JST jack, also the output header should be facing down, into the breadboard, but is facing up in this render): [LP2950-33]( http://www.ti.com/product/lp2950-33 ) [Tindie]( https://www.tindie.com/ ) I am planning on selling these products on [Tindie], and also in the 43oh Store if that is possible. I think Tindie has a fundraising feature so I will probably use that to get funds ( don't have enough money, just a teen still looking for a job for the summer ). Seeing the products by @@RobG on Tindie kind of inspired me to design some boards of my own. Any feedback/tips would be greatly appreciated!
Find attached schematic symbols for 251 MSP430 devices (out of 815 devices by my count). I've also done a handful of footprints. These have been done using KiCad. embedded-microcontrollers.zip I've also made a pin comparison tool which was extracted from this library. You could use this to make schematic symbols easily in the EDA tool of your choice (Altium for example). MSP430 selection guide.zip
