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","topicHash":"f04b384c0125f2981b53e0738968aafe40ec78569cb0e5075ae829ab39f7527b","topicName":"do-it-yourself","parentHash":null,"costSunk":"0","biasSupport":0,"biasOppose":0,"biasVouch":0,"biasNull":0,"blockHeight":null,"confirmations":0,"timestamp":"2026-11-06T14:03:14.461Z","tripFp":"5bba9c7237dd","viewCount":0,"powDifficulty":0,"relation":0,"ephemeral":true,"nonce":"5433f5b0684c820e","sig":"8fbdd30d7f069699c11a5c3e9dc1d5948d590eeaa07094cec93ea1e666f37a5a1b343efc8a54f0e882c968b7701e90a058354daecdeeb265bb8c4eadabfd67ca","ephStamp":{"blockHashHex":"000000000000000000014ab844bcc1d2bec2aadef7fd0a2657c954a939586ba9","nonceHex":"2137020000000000"},"replyCount":19,"chainReplyCount":0,"vaporReplyCount":19,"clusterSize":25,"receiptHeight":974813,"expiryHeight":979133,"authorMarks":{"since":"2026-11-01T14:02:12.870Z","via":"sight","inscribed":0,"likes":0,"biases":0},"lang":"en"}],"nextCursor":null,"pageReceipt":{"host":"6af58b1822e0cabfe57d76540f745d059b438f489a796ec6a705c6540233845e","t":"2026-11-08T20:39:48.650Z","sig":"96e4c7b734510b287888a8287f77bb0bbac567b830a8020c7e44e2ab2d5535e011dcee2ae8200f483c68ea1f5e69fa4c4edeae4eb0d58909d435df8d7bbad8f1"},"marks":{"since":"2026-11-01T14:02:12.870Z","via":"sight","inscribed":0,"likes":0,"biases":0}}
