I still think it's pretty insane and awesome that we now have ~$0.14 microcontrollers that can do sequenced ADC conversions with automatic DMA storage of the conversion results. 😄 https://silicognition.com/Electronics/PuyaCharge/py32f003-ADC-scan-config/ #PY32F #electronics #embedded

LiFePO4wered/Solar4 #prototypes built! Initial testing is positive, let's see if we can get this thing to charge a battery. 😁 #Puya #PY32F #LiFePO4 #solar #charger #IoT

Finished my first #PY32F #PCB!
In my efforts to make a #Puya PY32F003 based battery charging system, the next logical step was to add the power stage. So a PCB was born. #electronics #kicad

Not sure why the #CH32V003 #microcontroller keeps getting media attention while it continues to be a paper #release that can't be had at the promised <$0.10 price point.

Meanwhile, very little is being said (at least in Western press) about the #PY32F series, which is actually available in volume and some of which reach the same low <$0.10 price point: https://www.lcsc.com/products/Microcontroller-Units-MCUs-MPUs-SOCs_11329.html?brand=11580

#Available #parts beats paper releases in my book any day.
