Zdravím, v popisku uvádíte, že k této desce mohu přidat až 64 MB flash paměti ("up to 4 x 16 MB"). To by jsem musel odpájet paměťový čip na desce, nebo lze přidat jinak? Předem díky :)

Dobrý den, jedná se o chybu převzatou ze stránek výrobce. Deska má osazenu FLASH paměť o velikosti 4MB a PSRAM o velikosti 8MB. V popisu opraveno.
