#20744 Hi,

as I thought, the description does not agree with the leads ... (btw. after all, eg. MTD0 = GPIO15).

This means that the pins realy are routed to program flash memory - it is difficult to use them.

In summary, description is bad, the usefulness of extra pins almost none


Ps. silkscreen marks GPIO4 and 5 in reverse
