While Arduino gets the lions share of attention in the hobby community there are some limitations to 8-bit microcontrollers which have been recognized by the Arduino project with their recent announcement of plans to make ARM based development boards, as well at the Maple project (STM32 based). ARM microprocessors often offer significantly more RAM/Flash and peripherals at similar prices to traditional 8-bit microcontrollers, however they have a reputation for being harder to use.
In the maker community LPC and STM32 ARM based boards seem the norm, however in my experience LM3S (LM = Luminary Micro which is now owned by Ti) chips are far easier to work with. This is largely due to StellarisWare, which makes peripheral configuration uniform across devices. (See my comparison of UART configuration on many platforms here).
When I realized there were no inexpensive LM3S based boards available (now there are few on eBay as well) I decided to make some. I made a simple breakout style board called Cygni that was as inexpensive as possible so that people could try out ARM and find out that it wasn’t scary after all. And I made two more advanced boards one that could be a USB host (called Eridani) and one that was suitable for tasks requiring a lot of memory, internet access, USB hosting or all of the above (called Procyon).
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

I also liked the Luminary Micro hardware, but the dev tools was another story. TI’s preferred solution is a Keil solution that runs north of $1K.
Which tools is he using? (I couldn’t immediately tell from the web site).
Generic GCC + Eclipse/GDB if you want to do JTAG debugging like IAR/Keil etc.
PS: Being color blind makes that capcha petty hard.
Not true that TI/Luminary prefers Keil (which runs >$2K generally, by the way, as does IAR). When you order a dev/eval kit, you can choose among 4-5 tool chains on CD, but are free to download and use any of them.
