Orone-mini-S8A-v0r001
=====================

Maple-mini compatible STM32F development board. 

This board has not been made and tested yet. It is being released now to gather feedback, and hopefully encourage people to test it. The board has been designed for manufacture using two PCB makers. However, a goal is to ensure it is manufacturable by a wider range of PCB makers, so please feedback.

This is board designed to be DIY-assemblable, but otherwise software and signal compatible with Maple-mini. It has been inspired by some of Siy's mini48 innovations, and also the availability of STM32F303 in 48pin LQFP packages.

It is a breadboard-friendly form-factor; all pins are on breadboard 0.1" grid. Unlike Maple-mini, the two 20pin 0.1" headers are 0.8", and not 0.6" apart. However it is still narrow and short enough to fit into single breadboards.


Maple-mini improvements
-----------------------
LeafLabs Maple-mini is a very impressive and useful Open Source Hardware development board. It offers approximately 4x more memory and CPU performance than an Arduino UNO, much improved peripherals, and about 50% more I/O pins in a tiny package that fits into a 40pin DIL IC socket. It is supported by an Open Source IDE and library similar to the Arduino UNO. 

However there are areas that can be improved:  
1.	DIY-assemblable  
2.	Robust operation above 6V while providing current to e.g. LEDs and electronics  
3.	USB Electro-static Discharge (ESD) protecting the Host PC and Orone-mini  
4.	Socket for easier-to-connect external power  
5.	Power-on indicator  

All of these improvements are incorporated in this Orone-mini-S8A boards, and the first three are incorporated into Orone-mini-S6 boards.
