Lyn CeciHi,
I’m looking to mount the XDot onto a PCB. Am I able to do on-board programming without the XDot developer kit?
Thanks in advance.
Andrew Lindsayno, you need the xDot developer board and a suitable cable to a programming header on your board.
Leon LindenfelserHi Lyn,
You can also use an ST Link or Segger J-Link programmer but that’s essentially what Andrew is saying. Same method for programming… put a header for the xDot programming interface on your board and attach a programmer to flash the xDot.

Andrew LindsayThe other difficulty when developing your own board is that you need to create the footprint for xDot as Multitech don’t provide this. All you have to go on is a drawing with dimensions in the developers guide.
Andrew
Lyn CeciThanks for the feedback. So I could use and just pop out a header on my board?
So like…
STLink —-> XDot
VAPP ——> VDD3.3
TRST ——> GND
GND ——-> GND
TDI ——-> GND
GND ——-> GND
TMS_SWDIO -> SWDIO
GND ——-> GND
TCK_SWCLK -> SWCLK
GND ——-> GND
NC ——–> No Connection
GND ——-> GND
TDO_SWO—-> ??????????
GND ——-> GND
NRST ——> NRESET
GND ——-> GND
NC ——–> No Connection
GND ——-> GND
VDD ——-> No Connection
GND ——-> GND
I also have the mDot Developer Kit if it’s possible to utilize that in any way.

Leon LindenfelserLyn,
Please take a look at the following document…
http://multitech.com/documents/publications/manuals/s000645.pdf
On the bottom of page 49 is the beginning of a section for programming external targets. We designed the xDot DK board so it can be used to program external xDots. Connect from JP1 on the xDot DK to your target xDot. In your case, I’d suggest that you place a like 9 pin connector on your board. Once connected and powered, the xDot DK will program your target rather than the xDot that is on the xDot DK. Does this answer your question?
