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.

You just need to connect the SWDIO and SWCLK pins on the chip to the debugger. Just these two wires from the chip, and also a Vref (Supply voltage on the board) to the debugger. You need a 10-pin connector like this, www.keil.com/.../jLink_connectors.htm, and then connect the three wires to pin 1,2 and 4 on the connector. Then you can use the debug out port on the DK.
