The Stellaris Launchpad – a good and cheap ARM tool.
The pre-registered Stellaris Launchpad version was 4.5USD only, actual version is 12.99 USD.
This fantastic board features two LX4F120H5QR (ARM Cortex M4 with floating point), one as ICD and one as target, two user switches and one RGB Led driven by 3 transistors.
The “target” clock oscillator is build with Y1 32k768 and Y2 16MHz Osc.
The power jumper allows you to measure the target’s power consumption.
Other great thing is the presence of the two gender stackable headers which allows any header connector/cable combination, the Piccolo C2000 had only dual-side (stackable) male headers.
