I’m a gonna get serious about this whole IoT! To that end, I just bought myself a brand new CC2538 development kit from Texas Instruments. Yeah, it was $300 bucks, which hurt, but since I’m using a bunch of modules from China I wanted some rock solid hardware to compare against. Plus, the “SmartRF06″ board has a bunch of goodies like a graphic LCD. For $300 bucks, the kit contains: 2x SmartRF06 boards, 2x CC2538EM radio modules, and 1x CC2531 USB dongle.
Note, the CC2538EM radio module plugs onto the SmartRF06 board. In other words, the SmartRF06 board is a mother board for the CC2538DK radio module. The SmartRF06 board has a graphic LCD, a couple buttons, some colored LEDs, and a light sensor. The USB stick is still using the old CC2531 radio chip which is based on the CC2530.
