Before using the controller, carefully inspect the product for defects, chips, "sticky", etc. All components should sit clearly in their places without displacement, as in the photo below.
1.0 - Install software STM32CubeProgrammer to flashing firmware.
download STM32CubeProgrammer /204 MB/: https://www.iqled.org/soft/en.stm32cube ... 2-15-0.zip
2.0 - Using a Soldering Irons and solder, set the BOOT jumper as shown in the figure below:
*************************************
2.1 - Controller power connection diagram is shown below. Use a Laboratory Power Supplies, voltage +3.7V, with a current limit of 100 mA.
DO NOT CONNECT LIVE CLIPS, THE POWER SUPPLY MUST BE DISCONNECTED 
2.2 - Make sure the controller consumes no more than 100 mA, then connect the USB to the PC.
2.3 - Make sure that STM32 BOOTLODER appears in Device Manager:
2.3 - Flash the firmware - iqLED-Alpha-C8-RF-boot-v9.hex via the STM32CubeProgrammer, for this:
-- 2.3.1 - Download iqLED-Alpha-C8-RF-boot-v9.hex /17 kB/ https://www.iqled.org/firmware/iqLED-Al ... oot-v9.rar
-- 2.3.2 - Select the required iqLED-Alpha-C8-RF-boot-v9.hex files and flash the chip as shown in the video:
2.4 - After successfully flashing the chip, disconnect the USB, turn off the laboratory power supply, remove the BOOT jumper:
2.5 - Make sure that the laboratory power supply is turned off, connect the power clips.
DO NOT CONNECT LIVE CLIPS, THE POWER SUPPLY MUST BE DISCONNECTED 
2.6 - Supply power to the controller:
2.7 - When you turn it on for the first time, the green indicator will start flashing after 5-7 seconds, this indicates correct operation!
2.8 - Use the soft stick to test the UP, DOWN and LIST buttons. When pressed, the Red indicator should light up.
3.0 - Firmware update
3.1 - Press the center button, connect the USB to the computer and wait until the red indicator lights up. Release the center button:
3.2 - A flashing green indicator indicates that the iqLED-Alpha-C8-RF controller is ready for a firmware update.
3.3 - When connecting for the first time, check that the device is recognized in your PC as a Virtual COM Port:
3.4 - If the device is not detected on your PC, check the USB cable, and also install the virtual port driver from the Drivers folder:
3.5 - Download and run the software Light Studio Programmer v1.41
https://www.iqled.org/soft/distributive ... _v1.41.rar /11.6 MB/
3.6 - Download LED-Alpha-C8-RF-v14.sbin firmware.
https://www.iqled.org/firmware/iqLED-Al ... RF-v14.rar /200 KB/
3.7 - Update the firmware.
The video below demonstrates the firmware update process:
4.0 - Flash the firmware for STM32G030F6P6_Hub chip
4.1 Use a programmer - ST-LINK_V2
4.2 Connect the ST-LINK/V2 programmer to your computer via USB.
Make sure your PC detects it:
4.3 - Flash the firmware - STM32G030F6P6_Hub_v001.hex via the STM32CubeProgrammer, for this:
-- 4.3.0 - Connect the ST-LINK V2 programmer to the device:
-- 4.3.1 - Download STM32G030F6P6_Hub_v001.hex /6.6 kB/ https://www.iqled.org/firmware/iqLED-Al ... b_v001.rar
-- 4.3.2 - Select the required STM32G030F6P6_Hub_v001.hex files and flash the chip as shown in the video:
5 The final test is to check the SD card interface and radio synchronization.
5.1 - Use two micro SD cards. Format to FAT32 and copy DEMO files to each.
--5.1.1 - Download DEMO for Master SD: https://iqled.org/DEMO/C8/DEMO-Master.rar /1.65 MB/
--5.1.2 - Download DEMO for Slave SD: https://iqled.org/DEMO/C8/DEMO-Slave.rar /1.65 MB/
5.2 - Unpack and copy the DEMO-Master content to one microSD card, and DEMO-Slave to the second microSD card.
5.3 - Connect both controllers to USB for power and check the LED indication:
5.4 - The SYS indicator for the Master controller should show double green flashes.
5.5 - The SYS indicator for the Slave controller should show frequent green flashes.
5.6 - The SYS HUB indicator of both controllers should blink frequently and shine at half brightness.
THIS IS THE END!
