New to NRF51422

[D_Hercules]

I am developing a product where I need to read a signal from an SPI ADC and send remotely to a receiver. This will be powered of a coin cell. I see that the NRF51422 is low power, but I am confused about how to program it... is the software available able to load a defined program on the NRF51422 much like any other microcontroller? or this chip is only useful for handling the signal transmission?

Is there another NRF chip that comes in a more friendly package, like soic or QFN? maybe less pins, but easier to prototype?

Thanks.. A little bit of pointers will go a long way. Right now I am using the NRF24L01 with an atmel micro, but I want to save space in my board by combining mcu and transmission in one chip.

Yes you can program the nrf51822, it's a full MCU as well as radio and peripherals (it has an ADC on it by the way if you want to avoid using the SPI ADC, it also has SPI so you can read the SPI ADC if you use that).

the NRF51822 does come in QFN, it's one of the packaging options.

I suggest buying the development kit, it's cheap, it has an integrated JLink debugger you can use for testing your code and also programming your custom boards after you make them.

Nordic also has the nRF52 series chips which are even lower power and have even more features. I haven't tried hand-prototyping those yet, they have a pretty tight footprint which is more complicated than QFN (but not quite as bad as BGA).

Last question: (very appreciative of the help).

I want to jump-start this process of learning the NRF51422. I found the following in ebay (which can solve my problems with refluxing):

I see it has limited pins.... Those are GPIO. 2 I think are used for programming? right? Can the rest of pins be declared for communication (UART) so I can connect a GPS module? Or declared as digital communication so I can connect an ADC or LCD or OLED screen or anything I want.. Right? I am WAY to used to arduino nomenclature, where pins are already declared and with a specific purpose. I think this architecture is a little bit different and more flexible. Just want to make sure I pick the right module to start learning.

Thanks again
