tiny stm32 F4 boards

Post by ag123 » Wed Apr 12, 2017 5:04 pm

in the STM core thread, michael wished upon a tiny STM32F4 board

Going a bit off-topic here but are there any STM32F4 boards that are size of a blue pill available ? Of course all F4 mcu's are not yet supported by this project but if I find a small STM32F4 board I can start working on the variant config based on this project.
the wish is actually fulfilled, they are disguised as drone controllers :lol:

the chips seemed to be STM32F405RG
http://www.st.com/en/microcontrollers/stm32f405rg.html
1 Meg flash & 192k sram

that's plenty vs STM32F103C8 20k sram 64k flash, and 168 MHz, 210 DMIPS, hardware fpu, certainly meets 'high performance' (and maybe small) in the mcu class, just that those boards are somewhat tad pricy. as a bonus u get a 3 axis gyroscope + 3 axis accelerometer on board

you're going to get stung for the plugs and terminal pins to match those connectors; then there's the crimping tool :(

This one is even smaller and cheaper, but less pins:

MicroPython boards: this probably doesn't fit the 'tiny' form factor but has a somewhat small board foot print

Similar to the adapters in the previous post from ag123 but with predisposition for resistor and caps
