The power and storage you get for the MSP430 is indicative of the price. Here are the details from the documentation:

Two MSP430 flash devices
– MSP430G2231: Low-power 16-bit MSP430 microcontroller with an 8-channel 10-bit ADC, 2kB flash
memory, and 128 bytes of RAM (preloaded with a sample program)
– MSP430G2211: Low-power 16-bit MSP430 microcontroller with a comparator, 2kB flash memory,
and 128 bytes of SRAM
• 10-pin PCB connectors (two male and two female)
• 32.768-kHz clock crystal from Microcrystal (

As you can see there is only 2kB flash memory in addition to 128 bytes of SRAM and is clocked at 32.768kHz.

These are highly underpowered when compared to a typical Arduino board say for example the Arduino Uno which has 2KB SRAM, 1KB EEPROM, 32KB Flash Memory and clocked at 16MHz.

This will make for some interesting design choices when writing complex programs just on the board that comes in the packaging. Of course TI expects that you purchase more products to expand usability but for my first few projects I'm going to stick to just the board.


  1. It seems abit un-cost effective

  2. Well at the time I got them I got 2 for about $2.00 due to a coupon I found. It was a better deal than the $80.00 I saw for arduinos. I feel its very much a case of I got what I paid for, but I plan to find some neat ways to utilize the limited resources.
