Here we discuss microcontrollers (MCUs), single board computers (SBCs), and their accessories, such as Atmel mega and tiny AVRs (Arduinos), PICs, ARM boards such as blue/black pill STM32, ESP8266/32s, RP2040, Raspberry Pi, and others. For general electronics questions (power supplies, level shifting, motor driving, etc.) please ask /ohm/. >where can I find verified quality microcontrollers and other electronic sensors or parts digikey.com mouser.com arrow.com newark.com >but that's too expensive aliexpress.com (many parts here are fake, particularly specific parts out of stock in the above sites) lcsc.com >I need a part that does X and Y, with Z specifications. How can I find it? use DigiKey's or Octopart's parametric part search. Then purchase from one of the sellers listed above. >how do I get started with microcontrollers, where should I start? There is no defined starting point, grab a book and start reading or buy an arduino off ebay/amazon and start messing around. There are a plethora of examples online to get started. >resources: https://github.com/kitspace/awesome-electronics >RISC-V microcontroller list: https://codeberg.org/20-100/Awesome_RISC-V/raw/branch/master/RISC-V_MCU_development_boards.pdf⏱ 2d↩ 19

Idk. The fact that Arduino anything has become a standard is nothing but a hindrance. >bootloaders >using any programming interface that doesn't also allow for debugging >paying for programming hardware on each dev-board >UART printf debugging >dumbed down and non-performant programming abstractions >fuses being an afterthought And somehow they managed to release a dev-board with a socketed microcontroller, while having a native USB microcontroller on that same board explicitly to act as a programmer, while still requiring a bootloader on the socketed microcontroller. What the fuck?⏱ 2d↩ 1
