| Be aware that this pinout seems to be based on the DNS 323 version B2 and the CH3SNAS. The DNS-323 version A1 has the same space for a header, but the location of the surrounding resistors is different. This might or might not have consequences for the validity of the pinout as above. (Anyone: more information on the A1 rev.?) | Be aware that this pinout seems to be based on the DNS 323 version B2 and the CH3SNAS.
