Re: Ideas for next evolution of pyboard

I would appreciate a breadboard friendly board. Sure it would be bigger than current one but would make its use much more easier.

Re: Ideas for next evolution of pyboard

Regarding shields, concentrate on core business, I mean MicroPython and Pyboard development and do not waste time for extension board, use a 3rd-party existing solution. One possibility is Click Boards from MikroElektronika. They are small, plenty of different modules, widely available at main distr...

Re: Raspberry Pi Zero

Regarding RPi connectivity you have also the 1-wire Dallas/Maxim interface. 8GB SD card is needed for Raspbian, but e.g. piCore LINUX runs fine with an 512M card (if you find any). Zero has no Ethernet and many apps even do not need video connection. You can save the HDMI cable, but you have the pow...

Re: Raspberry Pi Zero

Implementing MicoPython on a bare metal Raspberrey Pi can be challenging and big fun, also can serve self education but I do not see practical reasons on a system with 512MByte RAM and a powerful CPU. In such environment MicroPython limitations would be a pain, I would use cPython instead. If your c...

It builds fine on Raspberry Pi with the GCC toolchain, it must work on BBB with no issues.

Re: Controlling a led, pull up resistor value

While it may work, as a general rule NEVER drive a LED directly from a microcontroller port. In a 3.3V system a 120-220 Ohm resistor would be a safe choice in most cases.
