Waveshare 4G HAT for Raspberry Pi (LTE Cat-4/4G/3G/2G/GNSS) (CE07826)

Hi John,

Cheers for posting your findings!

On the topic of power cycling - I’ve used a couple of these (Pololu Solid state relay boards) in a project to switch on and off some Rd-03D Radars for more coverage, and they have worked a treat, might save some space?

I’ll keep them in mind for other things! But as for saving space, Hmmm, those little buck converters seriously rock a small footprint especially stood on end!

Hey @John73269,

Those converters really do make the most of tight spaces! If you get a chance to try out the Pololu solid-state relay boards that Liam mentioned, they’re super convenient too.

Hi John,

Those are sweeet!
Do you have a link to them? If we don’t already stock them we definitely should!

Hi Liam. Adafruit make a 5V only version: MPM3610 5V Buck Converter Breakout - 21V In 5V Out at 1.2A : ID 4739 : Adafruit Industries, Unique & fun DIY electronics and kits

and they also make a 3.3v variant.

I used a generic unit from ebay that supports a bunch of fixed voltage outputs as well as an adjustable one: See:https://www.ebay.com.au/itm/392619758057?var=664563194959
