1.3 Updating firmware from microSD card

With firmware version 2.50 and higher it is possible to upgrade the firmware of the device by copying a pin2dmd.upd file to the SD card and reboot the device. Please check which hardware you have and download the update file from the github repository. Make sure you use the correct pin2dmd.upd otherwise you may get a black screen If you don´t see the boot splash you need to reprogram your device using the above methods.

2. Windows driver installation

1) Connect the your PIN2DMD to power,if not already connected.
2) Connect the STM board using the microUSB cable to PC. Windows 7 and later should automatically install a WinUSB device.

1) Start Zadig Utility from usb_driver folder.
2) Choose Options → List All Devices
3) Choose LIB-USB-WIN32 as driver and install


3. Device activation

After a successful installation or update of the firmware you should see the PIN2DMD logo and after a trial period of 3 minutes you should see a “not activated” message together with a number on the display.
