WiPy - MicroPython WiFi Microcontroller for Internet of Things (IoT)
Wypi is an Internet of Things board programmable in python and being compact, low energy, affordable. The board is programmable in MicroPython (support for Python 3 syntax), a version of python specially optimized to increase performance and reduce the memory footprint. MicroPython is capable of operating on microcontrollers having reached a certain power. No need for a compiler on a PC, with MicroPython, it's your microcontroller that directly interprets your script file. Because it uses Python, it works as you are used to on your computer, the learning curve is minimal ... if we can consider that there is one!
The module is completely OpenSource (and Open Hardware for hardware).
Before starting your hacking session, you will need a power source (between 3.6 and 5.5v) and a WiFi connection. You can use the WiPy expansion board to more easily support power requirements.
WiPy is autonomous and doesn't need a Cloud service, No need to compile and accumulate the library code to execute your programs, the platform interprets and directly executes your scripts written in Python.
What WiPy offers you:
WiPy works thanks to a Cortex-M4 MCU including WiFi support, it's the CC3200 module (chip-level WiFi certification). The CC3200 module supports SSL and TLS enough to allow WiPy to connect reliably and securely to the Internet (or a Cloud infrastructure).
WiPy has a low energy mode to maintain an active WiFi connection by consuming 850µA. WiPy can return to "active" mode when it receives data or receives a connection from a client. This means that it is possible to make a very low energy "server".
A WiPy device powered by a battery can return from "sleep" mode in 5 ms, send a series of packets to the Net, then return to sleep mode immediately, all in one second. A project strongly focused on optimizing and regulating communications can work for long months (or even years) with a battery.
What is the consumption of a WiPy?
WiPy consumes only 14 mA (official doc) 30-35mA (measurements) with WiFi activated and the processor operating at full speed (full clock speed). It is possible to go down to 5µA in hibernation mode (HIBERNATING). The most interesting energy saving mode is the SUSPENDED mode (standby "suspended") which lowers consumption to 850µA and keeps the WiFi connection active (thus allowing internet traffic to "wake up" the WiPy in less than 5 milliseconds).
Where can I find support for WiPy?
If you need help with MicroPython (Python for Microcontroller), you can go to the MicroPython Forum: forum.micropython.org
For more specific points on WiPy (hardware support), you can consult the WiPy forum: wipy.io/forums
