Damn, what a bad shop
Seeed Studio offer's pretty cool hardware for your smart home. I ordered a set of epaper display, epaper driver board and fitting ESP32-C3 from them. epapers shipped from China, the rest from Germany. After fiddling around with it, I had to find out, that I either had defect epaper, or ESP32 and driver board. From their perspective it's the cheapest, hence ESP32 and driver board, which they wanted to send me. After 3 weeks of waiting, I started issuing a paypal claim and out of the sudden the replacement hardware is shipping. Still my epaper display's are the problem, as also with the original ESP32 driver board from Waveshare these displays are not getting to work. Don't waste your money on them, if you're unsure to receive working parts. Btw. if you read their site thoroughly, all parts must be returned to china on own cost!!!
