Intro MecrispCubeF405
A new flavor for Mecrisp-Cube: MecrispCubeF405 for Adafruit's Feather STM32F405.
 
Changed:
<
<		If you need a faster MCU (168 MHz) and FeatherWings extensions without soldering then the MecrispCubeF405 could be the right Mecrisp Forth for you. There are many stackable boards from Adafruit to choose from: displays, joysticks, actuators, sensors, etc. The only drawback is the lack of BLE, but for this there is a Mecrisp-Cube for the STM32WB55.

Or the even faster MecrispCubeH74x with 480 MHz.
  Mecrisp-Cube Instant real-time programming with Forth.
