Miniature and powerful development tool designed to work as

stand alone device or as MCU card in DIP40 socket. MINI-32 is

pre programmed with USB HID bootloader so it is not necessary

to have external programmer. If there is need for external

programmer (mikroProg) attach it to MINI-32 via pads marked

with RB6 (PGC), RB7 (PGD) and MCLR.

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.
