Using the nrf51 to program module? voltage concerns

[Kehem]

Hello, I am going to make a PCB to mount the module and programming pins SWCLK/SWDIO/VCC/GND. I wanted to run my module at 1.8v, but I am worried if the nRF51 dev board, when connected to program the module, if it would program the module! I read some threads about their programmers not working with low voltage.. please if anyone has experience with it let me know. The dev board I'm using is this one www.digikey.com/.../5022449
I know the datasheet say 1.8v-3.6v but I just want to make sure before the pcb is made :/

You can use the IDAP-Link to program it.

I appreciate your reply but I'm not looking to buy something else, I just want to know if I will run into a problem using the nrf51 dev board to program the module

It would not work at 1.8v that is why I showed you the alternative. The devkit is at 3.3v

[Kehem]

oh ok thanks, since you don't confirm that at first I thought you gave that alternative without knowing.

[Kehem]

would it be possible to feed 3.3v to the nrf51 gnd detect pin and vtg pin but still have the module at 1.8v and have it program successfully?

I doubt that would work. You could power your module at 3.3v for programming purpose. Then put back the 1.8 afterward
