Re: WeAct stm32f103 usb c

for the WeAct board, one way is to ask WeAct to confirm if you are dealing with them, as opposed to 'generic' blue pills which apparently seemed to come from a different source. ideally if you are dealing direct with the manufacturer, it is less likely to get 'fakes' as they have more stakes than th...

Re: GPS

i've not tested out the module yet, but based on specs alone it seemed to be a pretty good one and it support so many GPS systems

Re: GPS

received from farnell element14 ! it cost a premium (at least compared to the u-blox Aliexpress types) but the package itself looked so nice and bundled with a patch antenna, so i'd not even need to cut copper foil. certainly worth ordering for the fun of it https://www.st.com/en/ecosystems/x-nucleo...

thanks time to order a shield to try it out, edit, ok ordered 1 piece of the shield from farnell element14 :) the module itself cost about 1/3 in low volumes but there is quite a few pieces of auxiliary components, so i decided to just have the shield. it might be handy to combine that with a nucleo...
