Hey, I find it very absurd that the SVOD4 costs so much and has zero documentation. I had no other choice than to buy it to unlock ECs, if there was any documentation or firmware avalible I could've made it or something simmilar. Anyways here are some of the most important parts:
STM32H723VGT6 MCU - It's a microcontroller by STMicroelectronics and its the whole brain of the SVOD4. It has flash memory for the firmware which can be updated by the SVOD4 program. Its also powered by the AMS117 which converts 5v into 3.3V. 7€ on AliExpress.
GW1N-UV9UG169C6/I5 FPGA - Its a FPGA. It also has non-volatile memory which means that the STM32 MCU tells it what to do and it does it. So no dumping needed here. 25€ on AliExpress
SMSC USB3300-EZK USB host - Its what lets your pc communicate with the STM32. It isnt programmable and doesnt have any flash memory so thats great. 3€ for 5pcs on AliExpress
74HC595D shift register - It has something to do with shifting signals, which i dont really understand. But its a very basic chip. There are a ton of them on the SVOD4. 1€ for 10pcs on AliExpress
In principle these are the most important parts needed to make a SVOD4. Its definitley not worth the 500€ I had to pay to a reseller just to get my hands onto one. I understand that it might be expensive because all of the research and time it took to make this product but I find locking down the software and all modifications really not okay. Not even the slightest bit of documentation. I think making a clone might be highly possible because 1: It has OTA update which means the firmware of the STM is literally on your pc and 2: There's always a chance to dump the firmware from the chip directly, also ive noticed a 10 pin debugging connector on the side which might help.
Pictures of the pcbs and close ups are i​n the attachments​
If you have any questions or need extra close ups or measurements ask ahead
