Miniature and powerful development tool designed to

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

MINI-M4 for MSP432 is pre programmed with USB UART 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 TCK/SWC, TMS/

SWD, INT0, INT1.

1. Programming with mikroBootloader

You can program the microcontroller with the 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 UART) which can be downloaded from:

After the software is downloaded unzip it to the desired loca-

tion and start mikroBootloader USB UART software.

Figure 1-1: USB UART mikroBootloader

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.
