It is hard to distinguish the khadas tone boards on ebay are fake or real, so that is better to buy the tone board by official channels or verified distributors, I found out that the tone board is in stock on the Digi-key and its price is better than other channels, you could check by https://www.digikey.com/products/en...-expansion-boards-daughter-cards/797?k=Khadas , hope that will help you out.
Thanks ! For Germany its the cheapest way. 107€ for the Khadas Tone Board incl shipping
About the Chinese Khadas tone board Sellers: They are always 2-3$ more expensive than Digi-key, so probably they are just dropshipping (earning 2-3$ per order)
