nRF5 action!

This module is interesting because it looks as though it would be relatively easy to attach to most simple sensor projects:

This module looks great. Both oscillators and the inductor is placed ob board. But the SWDIO and SDCLK are not connected. You can only flash via OTA update. Don't flash MySensors until you have moved the used Flash by NVM driver. The NVM would overwrite the DFU bootloader. It's possible that the nRF5 code needs changes to support running on an nRF5 with Softdevice.
@scalz is playing/plans to play with Nordics OTA update.

A couple more interesting finds.

This one is small but includes a PA, so you can allegedly get 20dBm+ in TX:

Awfully expensive though.

Attractive form factor, but I believe that it's just a beacon. If not, how do you connect it to anything?

Lastly, I'm quite intrigued by this one, which is an nRF51832, because it is only 11.4mmx9.5mm in size:

Maybe you'd like this one (or similar) a little better, as it has some additional sensors already built into it:

I think it's simpler to use one of the ST-LINK v2 clones. The DK board should be good for development, debugging and current measurement.
What exactly do I need to do to get it work? I tried it from Windows, and failed. I seem to recall you said you got it to work from Linux after changing a definition. Would you mind showing the steps, or providing a link on how to do that?

I have updates my documentation: https://www.openhardware.io/view/376
I have tested all three programmer types with Windows 10. It looks like Zadig installs the correct drivers for J-Link and ST-Link adapters. The CMSIS-DAP requires the serial driver from mbed.

Thanks! I had been using a computer running Windows 7, and I got no joy with Zadig and st-link v2 on that. However, you just now mentioned Windows 10, so I'll give that a try.@NeverDie said in Minimalist SAMD21 TQFP32 Pro Mini:
hanks! I had been using a computer running Windows 7, and I got no joy with Zadig and st-link v2 on that. However, you just now mentioned Windows 10, so I'll give that a try.
I think the best option for beginners is to use an CMSIS-DAP/DAPLink adapter. Firmware and drivers are open source and there is an integrated serial port.
The ST-Link adapter is initialized with an ST-Link driver by libwdi. If you have luck you can find an old variant.

Yes. 9x9mm with antenna: https://de.aliexpress.com/store/product/PTR5628-Nordic-nRF52832-Module-BLE-4-0-Module-Free-shipping/130096_32760971926.html but photo and product description are different. I had a discussion with the manufacterer end of 2016 at this time the module was shown as 9*9mm module. The PTR5628 has no 32kHz oscillator, you have to use the unprecise RC oscillator.

9mmx9mm would be great. However, are you certain? Product description says 15.4mmx15.4mm.Pitty the lack of 32khz crystal, but for a lot of sensor nodes perhaps it won't matter much.
I did find this after making my prior post:
https://www.aliexpress.com/item/nRF51-M0-Ultra-small-Bluetooth-BLE-Module-4-0-Module-LIS3DH-Support-10-GPIOs/32697055436.html?spm=a2g0s.13010208.99999999.295.t9NHvJ
which is allegedly 8.5mmx10.5mm and allegedly does have a 32Khz crystal, but the trade-off is that it's an nRF51832, not an nRF52832. -

It's just 5mmx6.2mm! So, at least the size is very much awesome. It does have an M0 Cortex core, but it's not a Nordic Semi chip: http://www.dialog-semiconductor.com/sites/default/files/da14580_ds_3v4.pdf
so I have no idea if, or to what degree, it can be easily programmed from within the familiar Arduino IDE the way the Nordic chips apparently can. Do you happen to know if it would be trivially easy? Or would getting it to work be a project unto itself? -
@gohan said in Minimalist SAMD21 TQFP32 Pro Mini:

Once outfitted with the connectors, the modules should then fit quite easily into these for prototyping:

That's also why it can work on both NRF51 and NRF52.

Unfortunately, I don't think the da14580 will work with the current mysensors library: it appears to be bluetooth only. I only did a quick speed read of its datasheet, but I didn't see any mention of the Nordic proprietary modes (or anything like them) that the mysensors library relies on.

I have ordered one like this. It's pretty small already, less than 2*1cm :
https://www.aliexpress.com/item/nRF51822-04-BLE4-0-WIFI-Wireless-Bluetooth-Module-TTL-Low-Power-Consumption/32682158906.htmlIt has very limited I/O and is made to be used in addition to a MCU using UART to communicate, but the SWDIO and SWDCLK pins are broken out so I will see if I can reprogram it.
It has a datasheet to at least get a valid footprint (as I don't plan to use the serial protocol) :
https://4tronix.co.uk/picobot2/WT51822-S4AT.pdfAnd it has been featured on Nordic's website where they say it's supposed to have FCC certification (and CE too, but that's just declarative...).
http://www.nordicsemi.com/node_206/node_305/Product-Related-News/Nordic-powered-Bluetooth-Smart-module-simplifies-development-of-wireless-wearables-toys-and-smart-home-solutionsThey also claim a 50m range which is way better than the 10m of the da14580 you link above.
So if it can be reprogrammed without problem it looks like a perfect candidate for basic nodes like door, I2C etc
