#1 – FRDM-K64F
The FRDM-K64F is a development board for the Kinetis K64. Freescale had the great idea to not only make the platform compatible with the ARM mbed platform, but also to provide a board that is compatible with Arduino shields.
Since a few months, you can also
install a Java ME embedded firmware on the FRDM-K64F, turning it into what is probably the cheapest Java development board on the market.
#2 – SeeedStudio Grove system
"It seems that perfection is attained, not when there is nothing more to add, but when there is nothing more to take away."
The Grove platform from SeeedStudio does just that. Their simple yet very smart connectors have become the standard platform for connecting IoT sensors. There is a huge list of sensors and actuators using the Grove standard connector, and you can literally hook Grove devices to anything, from Arduino to Raspberry Pi to Beaglebones thanks to the many shields available on the market.
#3 – Raspberry Pi Model A+ and B+
The Raspberry Pi Foundation really is doing a great job at keeping its very popular platform up-to-date. Every year, we get great upgrades to the existing models.
This year, the model A+ brings the Pi's price tag under $20, with a much smaller form factor, and 30% less power-consumption than its predecessor. The B+ is a model B on steroids: more USB ports, more GPIO headers, and again a power-consumption that dropped by 40%!
#4 – Texas Instruments CC3200 LaunchPad
A powerful Cortex-M4 micro-controller, a WiFi module, a very complete IP stack (DNS, mDNS, SSL-TLS with hardware crypto support, ...), and tons of examples: I really liked the CC3200 user-experience. The only downside is that I had to switch to Windows to use Code Composer Studio, but if you want to use
Energia you can have a cross-platform IDE and a programming model very close to Arduino.
#5 – Advanticsys XM1000
I really wanted a nice and simple platform to experiment with wireless sensor networks, 6LoWPAN and CoAP. It turns out the XM1000 is a great platform (and so is the CM5000), that comes with support for both Contiki and TinyOS. The MSP430F2618 processor brings 116K of Flash and 8K of RAM to the table, which is actually pretty decent for most use cases. The external 1MB of Flash is also a nice-to-have if you want to store sensor data locally.
#6 – ESP8266
A $5 WiFi programmable module? Hell, yeah! Several alternative firmwares have popped up over the last few weeks (including a
Lua-based one), but the most interesting one is probably the beta version of the
FreeRTOS-based SDK.
#7 – Espruino Pico
Javascript on a USB stick, for just £15!
The first version of the Espruino was already an impressive piece of engineering, fitting a full Javascript interpreter in 256K of Flash, and 48K of RAM. The event-driven programming model is really nice, and makes
power management completely transparent.
#8 – Spark Core
A super-tiny Cortex M3, that can do WiFi and that allows out of the box to be remotely programmed. Pretty cool, eh? You can indeed program the board either from an online IDE, or from a desktop IDE based on the Atom editor. The Spark Core
blueprints are available under a Creative Commons license and the
firmware and
CoAP-based communication stack are open source too (LGPL).
#9 – CryptoCape
2014 has seen significant progress in the domain of security for the Internet of Things (look at
IETF efforts to optimize DTLS for IoT, for example), and I certainly expect more in 2015.
With the Cryptocape, one can easily get hardware support for many cryptographic functions (Elliptic curves, AES, RSA, SHA-2, ...). The downside is that the complete datasheets of some of the modules included in the cape are only available under NDA
#10 – Rapiro
Last but not least, although a bit expensive, the Rapiro is a great platform for people interested in re-thinking the human-computer interactions. It's an open-hardware robot that is powered by an Arduino and a Raspberry Pi. Attach a Wi-Fi dongle to the Raspberry Pi and you have a
wireless IoT robot that you can control using MQTT
