Key features

Miniature and powerful development tool designed to

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

MINI-M4 for Stellaris® is pre programmed with USB HID bootloader

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

is need for external programmer (mikroProg™ for Stellaris®)

attach it to MINI-M4 for STM32 via pads marked

with PC0 (TCK/SWC), PC1 (TMS/SWD), PC2

(TDI), PC3 (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 le 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

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.
