WeatherDuino 4Pro TX Board Parts

Hello everybody!

I have done a little work to help those struggling to find parts to complete your transmitter boards. I have created a list on DigiKey for everyone to access, but for the moment it is only a parts list for the specified countries/setups. If you would like a parts list for 433 MHz, a different country, or specific specifications of your TX board, PM me and I will absolutely be willing to create more lists for you!

Be warned though. I made this list a week ago and had to use some substitutes for obsolete and out-of-stock parts, but they should still work the same. You can also PM me for any questions, issues, or tips on ways I can improve the lists for you all.

These lists are not just lists but links to DigiKey where you can order the exact amount of parts you will need for a board. The list contains parts that you may or may not need, depending on your choice of setup, so feel free to ask me about it.

I will edit this post and update this thread as I add, edit, or update the lists.

EU 868 MHz LoRa Parts Link:

Note:
This part list does NOT include the 868 MHz LoRa module, as it is out of stock and special order through DigiKey. Eventually, I can post a second link to the LoRa module separately.

Thank you @heavyweather for your help regarding the parts. i used the EU LoRa list and ordered at Digikey. First the parcel was lost at austrian customs, then everything went fine, but one part seems wrong:
IC 5 should be AD822 and in your list it´s a TS922IDT. So, did i miss something? Is the TS922 a comparison typ?

Second question regarding the parts: I´m desperatly searching for the parts of the I2C bus extender pcb and cannot find the parts. I even looked in the schematics... So please could anybody give me a little help 

Tnx again and greets from Austria,

Hi PapaErde

As stated on the official parts list, the reference for the I2C bus extender chip is P82B715.
You can find the specs here: https://www.ti.com/lit/ds/symlink/p82b715.pdf

Regarding the AD822 chip, I don't know if the TS922 is a direct replacement chip.

Thanks for the help werk_ag.  I´ve recognised the 82B715 as TX chips on the main TX board. But i was searching for the part list of the extender pcbs and found it here https://www.meteocercal.info/forum/thread-1898.html 

Maybe the TS922 was mistakenly added by heavyweather on his digikey-list. So again: Thanks for the service and maybe he´ll check the shopping list.

Greetings from Austria
