 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I find the micromite quite useful as a switchmode power supply controller, in the development phase, but when it comes to making a fully functional one the more speed the better. Has anyone made up a basic F4 using the same chip as found on the ArmmiteF4 board? |

Thanks Bill That's the ultimate. I have some of those and they appear to be nearly 4 times faster than the 28 pin micromite. I was however looking at using the chip mounted on a breakout type pcb and using the bare minimum components so that I can use a few A/D pins and about 4 PWM pins. Just.... "need the speed" |

All you need is the chip, a bunch of capacitors and two crystals. Search for minimum circuit in the ST docs. The RTC crystal is essential but you don't need a battery unless you need the clock to keep time otherwise just tie VBAT to VCC |
