Introduction to MINI-M4 for STM32

Key featuresMiniature and powerful development tool designed to

work as stand alone device or as MCU card in DIP40 socket.

MINI-M4 for STM32 is pre programmed with USB HID bootloader

so it is not necessary to have external programmer. If there is

need for external programmers (mikroProg™ or ST-LINK V2)

attach it to MINI-M4 for STM32 via pads marked with PA14

(TCK/SWC), PA13 (TMS/SWD), PA15

(TDI), PB3 (TDO) and

RST#.

1. Programming with mikroBootloader

You can program the microcontroller with bootloader which

is pre programmed into the device by default. To transfer

.hex file from a PC to MCU you need bootloader software

(mikroBootloader USB HID) which can be downloaded from:

After software is downloaded unzip it to desired location and

start mikroBootloader USB HID software.

step 1 – Connecting MINI-M4

01

01

To start, connect the USB cable, or if already connected press the Reset button on your MINI-M4 board. Click the ”Connect” button within 5s to enter the bootloader mode, otherwise existing microcontroller program will execute.
