This post is in hopes that discussion might influence a future product from PJRC - and shows the trend to interpreted scripting languages to do much more per line of code than C/C++.
This post is not intended at all to divert attention from today's Teensy 3.x - but rather, to discuss the future.
Info here may help those microprocessor fans who are interested in staying abreast of what's happening in the marketplace for makers (avocational uses) and for low volume products...
We're talking $12-$30 @1ea, and not the Windows IoT or Arduino Zero and kin.
And using languages that may be familiar to those working in servers and PCs, but not experienced with MCU/firmware and near-bare-metal.
Most or all of the interpreters, and the I/O libraries and "kernel" for these types of boards is written in C or C++.
Here's the kickstarter: https://www.kickstarter.com/projects/857552561/wifi-mcu-stm32f4-wifibroadcom-lua
And this: http://www.wifimcu.com/en.html
Confusing, but the vendor linked to below is taking orders at just a bit more cost than the two-fer price on the kickstarter. This seller says they've been a webstore for years.
http://www.smartarduino.com/wifimcu-wireless-wifi-development-board-using-lua-from_p94744.html says 300+ in stock. How can that be, given the kickstarter?
Developers go by the moniker "DOIT; see http://doit.am/ (they begain with an ESP8266 - now moved to Broadcom as did Particle.io)
Well whatever/whenever, this price point board is amazing, if true. Too low to be realistic? Doesn't read like the suspect sellers of boards built from known-reject chips (or worse).
Some time browsing these web sites... "WiFiMCU" seems to have comprehensible API documentation. And the source is open.
Well, October should show what $17 for two brings, on the kickstarteraward. The smartarduino.com price is about 10% higher (supposedly).

- We've seen the low cost MCU board with a built-in Python interpreter + I/O library (STM32 MCU). Micropython.
- And the Particle.io Photon MCU board with Javascript and an on-line IDE that is very slick for many "maker" type of users. Lots of I/O libraries, nice event-driven system. STM32F MCU.
- Newly discovered is a lower cost yet MCU board. STM32F MCU. https://www.kickstarter.com/projects/857552561/wifi-mcu-stm32f4-wifibroadcom-lua

- Broadcom WiFi module
- STM32F411EC MCU (512K flash, 128K RAM, floating point, lots of on-chip peripherals). 2MB SPI flash chip on PCB.
- USB
- SWD flash and debug option
- Standard firmware has a script interpreter for the Lua language. (OMG, does my brain have room for Lua as well as Python, Javascript, C, C++ ?)
- Says full open source. Bootloader and all system software, I/O libraries, and the interpreter - sources on github.
