Excessive enthusiasm on my part. The pin-out for a SER+ should be as above but the pin-in for a JNZ or similar needs to use BOOT0 and Reset.

Review is still desirable since the FTDI port appears able to support the BMP firmware. The RX/TX and GND look good - not so sure about the DTR/CTS driving pins and their match to the standard BMP image. The 5v needs care to make sure it goes via a regulator on the target or is not activativated.

Looks like these are the BMP pins:
TARGETBOARD JC66_COREBOARD
GND GND
SWDIO PA4 *
SWCLK PA5 *
POWER 3.3V from someplace with a common ground. Probably easiest to plug both boards in to USB

There are some good tutorials for converting a BP into a BMP (hackaday).
For the moment this extension board is for BPs used as a programming target on a breadboard. IMHO this kinda conflicts with this issue and I don't want to include complicated parts like light pipes only to get the LEDs back.
Do I miss something here? Do you have a specific use-case?

np, and thanks for the hackaday link.

I appreciate that this board can operate as a node, subordinate to a Ser+ using its FTDI interface. I guess it can't operate as a Ser+ because of the choices made with regard to DTR and CTS/RTS.
I may be losing the plot here.

Ser+ uses the SWD pins which are available on the tail end of the BP. Could use the two SWD pins to drive the DTR/RTS pins on a target node. TXD/RXD still derived from the FTDI header.
