TMDSEMU110-U: Pitch of the TI 20-pin to ARM Cortex 20-pin converter adapter

Part Number: TMDSEMU110-U

Hi Team,

A customer bought TMDSEMU110-U and noticed that the male and female connector of the TI 20-pin to ARM Cortex 20-pin converter adapter has the same pitch of 0.05 inch. Is there any recent changes in the converter adapter? He is expecting 0.1 inch header female on the other side of the board. 

Since both connectors have 0.05 inch pitch, do we have an adaptor board to connect the 20-pin 0.05 inch female connector to a 0.1 inch male connector on an evaluation board? Is the connection of the 20-pin male and female connectors straight thru?

Regards,

Danilo

    No, I believe this was always the way these connectors were spec'd.

    No, the connection is not straight through. Table 4 (CTI to Other Adaptor Pin Mapping) in the TMDSEMU110-U user guide gives the mapping from the TI 20-pin connector to the ARM Cortex-M 20-pin connector.

    Not that I'm aware of.
