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 Stellaris® 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 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.
