Tonight I decided to end the breadboard mess for the MSP430 YWasp by soldering a little nRF24l01+ shield for the Launchpad together. The nRF24l01+ with its external antenna  looks somehow impressive on the Launchpad . The Launchpad with the MSP430G2553 is communicating happly with the STM32VL Discovery based YWasp prototype. The nice thing about the Launchpad variant is, that it comes already with a USB-to-serial converter, so you can directly plug it to your Linux box and use “/dev/ttyACM0″ to communicate with the counterpart YWasp.
