Hi,

From the schematics in the datasheet of the module, it can be seen that the SWD interface of the nRF51822 chip is exposed on pins 24 (SWCLK) and 25 (SWDIO). See chapter 11 (Debugger Interface (DIF)) in the nRF51 Reference Manual v3.0 for more information about the SWD interface.

By connecting the SWCLK and SWDIO pins (together with GND/VDD) to a debugger/programmer, that has a SWD interface, you should be able to program the module. We recommend using Segger debuggers, but if you search DevZone, you will find many posts by other people using debuggers from other vendors.

In the datasheet, the supply voltage is specified to be from 1.8-3.6 V. You should then be able to operate the module with a 3.6 V supply when done programming.

Best regards,

Jørgen
