What do I need to program Waveshare Mini nRF51822?

[Francis]

Hi,

I have a program that it works fine with nRF51-DK, but I want build a PCB with the Waveshare Mini nRF51822 module.

What do I need to program this module? With the nRF51-DK, I read data from a sensor through I2C. Can I do it with this module through accessible pins? These are the specifications. I think so...

Thanks

Yes, you should be able to create a PCB with GPIOs for the I2C and a header for programming (SWD). Since you have the nRF51 DK, you can actually use this to program your module. Just use the debug out port on the DK, and you should be able to flash your module from nRFgo Studio.

I'm pretty sure that it is the same pins. Anyways, you can just check the product specification for the nRF51 chip, and look at the pinout there, and just follow the wires on the module. The program should also work without changing the code, if you use the same pins. But I guess it would be best to use the pins that is most practical on the module, since you are designing a PCB, and then just change the pin assignments in the code. All pins are GPIOs and interchangeable.
