  1. Guess I'll have to ask TI tech support . . . or buy a couple for temperature testing. At least I know how to measure the board sensed temperature. <grins> No worse than trying to qualify Arduino. Bob Wilson
  2. Hi, I'm not having a lot of luck with Google finding the TI specifications for the temperature range of either this board, EXP430F5529LP, the MSP-EXP430G2, or other MSP430 based, LaunchPad boards. Trying to use a search term with "temperature" brings a lot of hits about how to read the internal temperature thermistor but nothing showing the hardware temperature range (been there, done this: http://hiwaay.net/~bzwilson/temp_recorder/.) My application is automotive but with attention to packaging, I can probably handle 85C without 'going nuts.' Key requirements: low power - it is a batt
  3. I appreciate the welcome. I am looking at the MSP-EXP430F5529LP series but I'm having trouble finding the temperature range of the LaunchPad boards . An automotive application, it needs to survive a sunny, Alabama summer day in the trunk. Usually the glue logic limits the temperature range before the microcontroller. The MPS430-F2013 was great, better than 100C, but a little over kill. If the LaunchPad boards can handle 85C, no problem. The one with the Ultracap is probably pretty limited. If less than 85C, I may have to go with something else but I'm willing to try 65C by minimizing e
  4. Hi, Many years ago, I bought EZ430-F2013s and was impressed enough to build some hacks. One led to a Geek article in EDN, a temperature recorder the diameter of a quarter. Best of all, the daughter board handled live-steam, 100C, which worked great. The user community in the Yahoo Group was great but lately, a little thin. Recently, I was tempted by the Arduino project. But the 40 ma load, crappy analog front end, and what appears to be weak glue logic. So I'm looking at the MSP-EXP430F5529LP and MSP-EXP430FR5969 that both appear to solve the problems with the EX430 being too small for
