After having reviewed sub $0.10 microcontrollers recently, it’s time for some projects using the Padauk PFS154 and PMS150C. Considering my previous investigation of electronic and non-electronic candles, it appears only natural to chose this as a target for the lowest cost microcontrollers.
Continue reading “A LED-Candle based on the 3 cent MCU”Like many others, I was quite amazed to learn about a microcontroller sold for only 0.03 USD via the EEVblog last year. How was this possible? Many assumed this was a fire sale of an old product. Digging a bit further, it became apparent that there is an entire market segment of ultra-low-cost microcontrollers. Almost all of them are products of rather unknown companies from China or Taiwan. This write up summarizes my findings in this rather peculiar niche.
We already learned that there is a large variety of very powerful $1.00 microcontrollers, but what about the $0.10 MCU? Are they indeed all “terrible”, as suggested elsewhere?
