Happy New Year! 🎉
As a self employed 20 year old hardware developer, 2023 kicked my ass.
I had to take a break from posting but here's a look inside the chaos from my year! 🧵⬇️

I (was) excited to share that all backorders have been packed this week after receiving new parts - until I discovered that *EVERY FUCKING GPS MODULE* I ordered is counterfeit, and defunct. (60+ modules)

My biggest
#PCB
design gripe is LiPo charging 😡🔋- especially when prototyping w/
#microcontrollers
.
There just aren't any drop-in solutions that charge & power on the same pin, let alone a castellated one!
So I designed ⚡️MiniMeter⚡️- a tiny charger & I2C battery meter! ⬇️

Started digging into these
#counterfeit
GPS modules, right off the bat I noticed that most of them use 2 resistors in place of the LR series
#circuit
.
Some modules started working when I swapped in the proper inductor. Is this used for impedance matching?

I'm getting pretty good at visually identifying real

Just scratching at the corners to see if they peel is the easiest way to test this!

🧵I'm quickly hitting the limits of the
