I've finally got the rev 1. versions of this development board up and running. To get more information on this board, check out the previous few blogs. The first one I put up in support of my kickstarter project describes it's features etc... in more detail. It is going to support the MSP430F5635 MCU because this chip is very robust and great for general embedded development and has the most attractive price point of the 5x family USB MCUs. I'd like to sell these as fully built units supporting USB development. I feel like this board is enticing because it is great for general development using larger, more powerful, MSP430's. It also supports USB, which was the driver for this design, but it can still be used as a general development platform. The problem with the other boards I found was that they were either USB development boards or general purpose. I didn't see a solution for someone that needed to use both USB, LEDs, buttons, the USCI module, UARTs and the ADC etc... This board allows you access to all of that whether it is on board LEDs/buttons or signals/devices that you can plug into the two 30 pin headers or the 12 pin header. You can also spin a plugin card that can fit right into these expansion headers. Also, almost every pin on this 100pin MCU is broken out to these expansion headers, which allows for great access to all of the peripherals via the MSP430's IO. I also have all of the map-able pins broken out to the expansion headers as well!
The chip I'm going to be talking about is the MCP34063. I really like the chip because it is very cheap, which is great for learning because you will most likely burn some up, and it's one of the older regulator IC's out there so there is some information floating around the internet that can help you get started. I went with TI for this because they have great customer support via their forums which is really one of the best resources out there if you are interested in learning some valuable lessons in design etc... The DIP package is also really nice and as you may have found out by looking at higher frequency switching IC's, not everyone produces a DIP package.
This is a regulator that boosts an input voltage range of 0.9V to 1.7V up to 3.3V. It's based on the MCP1640 which is a 500kHz switching regulator. This boost module can supply up to 100mA. It is up for sale on the products page and is a great development tool!
This is just a quick post going over some basic IO functionality utilizing a booster pack I designed for the launch pad. I am toggling all of the IO pins of interest for my booster pack to make sure this new board I built up works correctly. I decided to post this because it is simple and easy to understand. There is also code for interrupt service routines that may help a few of you out.
This is my low cost under cabinet lighting system based around the Texas Instrument Launchpad and my PowerFet Booster Pack.
This write-up is for the power fet booster pack (PFBP) which is up for sale on the products page. It's sold as a kit of parts which requires assembly. This video is a quick over view of the board and a demonstration of it pulse-width-modulating and LED strip. The source code is discussed below.
This is a SOIC narrow breakout board for 16 pin and lower pin count parts. This board breaks the pins of the SOIC package out to 0.100" (100 mil) header pins. As shown in the pictures below and described in the video, these boards allow you to breadboard circuits. This is important because it allows users to get a functional circuit up and running with the bugs worked out before they order expensive circuit boards.
