I tried to get new MCUs from the market and realized that it is not so easy here in Hungary in small quantities (or I get a really high shipment cost).
In addition the solution what I'd like to develop could require DAC and the MSP430 value line has no integrated DAC.
The two factors above and my hunger to learn additional MCU platforms lead me to switch this development effort to a different platform. My choice fell to FreeScale Kinetis KL05 series ARM Cortex-M0 MCU.
I bought the Freescale FRDM-KL05Z development platform for it.
At that time I realized that it has not enough I/O pins, the In-Circuit programmer connector has 1.27 mm ... what has high cost. There come the decision to create a development board what has the following parameters:
- Use 2.54 mm programming header
- Independent power source
- LQFP-48 form factor MCU
- Fits in the 50x50 Sick of Beige enclosure
- All of the GPIO pins available externally
- No integrated programer. I want to use the FRDM-KL05Z's OpenSDA as programer
I'll order the PCB from the seeedstudio on the next week (it shoud arrive after my vacation)
