Worth the Update?
As far as microcontrollers are concerned, there are thousands of options for you to pick from. They range from the 8 bit AVRs all the way to 32 bit STM micrcontrollers. The 32 bit micrcontrollers are becoming far more popular in modern products, but 8 bit micrcontrollers remain extremely popular in hobbyist settings, especially ATMEL’s line of AVR microcontrollers. This can especially be attributed to the popularity of the arduino, which uses a wide range of AVR microcontrollers.
