I just finished the design of my dual stepper motor
 coil winder PCB. It occurred to me it could be the basis
 of a low cost auto pilot. Ailerons and elevator.
 The Mikroe $40 Mini MO has 5 analog to digital ports  for
 atmospheric pressure sensor and low cost solid state gyros.

 Even cell phones have solid state gyros sort of:)

 It even has a black box option recording altitude and heading
 using this free Windows terminal program
 and a PC or tablet for recording the data.

IMHO  I use the
Teensy 3.1 at $17 from OSH Park
Programmed in Coridium BASIC  Free
72 MHz
256K Flash
64K RAM
21 Analog pins  16 Bit
34 Digital pins
12 Timers
SPI  I2C CAN

KSCK

Much of what we do will be compatible with that.

The Mini M4 available from Mouser is a bit more
powerful than the Mini MO with 4 more I/O pins. Same maker.
I am switching to that. Largely pin compatible with the MO.

I was under impression that the Coridium
boot loader was not finished.

How well is it working?

I like the 40 pin dip form factor as it works with
any 40 pin socket.

There has been an explosion in the availability of these controller chips.
All others are dead. No more 16 bit chips.
