This is an UNOFFICIAL AVR community.

This is a community for people who use AVR microcontrollers. This can include Arduinos, Arduino clones, Arduino like boards, and stand alone AVR chips and self-designed boards.

NOTE: If your circuit is doing something weird when you touch a wire or move your hand across it see this pinned post.

This is a community for everyone who is interested in AVRs and Arduinos from beginners to experts, kids to adults, hobbyists to engineers.

RULES:

  1. All Lemmy.ca rules apply here.

  2. Everyone (see rule 98) is welcome.

  3. If you’ve seen a question 100 times answer it the 101st time or ignore it. Even better, write a complete, detailed answer and suggest that the mod(s) pin it to the community.

[Did you actually think there were 98 rules?]

  1. If you present something as fact and are asked to provide proof or a source provide proof or a source. Proof must be from a reliable source. If you fail to provide proof or a source your post or comment may be removed.

  2. Don’t be a dick. Yes, this is a catch-all rule.

  3. The mod(s) have the final say.

One of the more interesting 8-bit AVR boards that have come out with the new, modern "DB" (or DA/DD/EA) numbering is this AVR-IoT Cellphone.

While its a straightforward hookup of a cellphone modem to the UART of a typical 8-bit AVR microcontroller, its a fun little concept board. I don't really know what I'd do with a cell phone-based microcontroller... maybe some kind of Solar Panel + Lead-Acid project that I call with modem to transfer data somehow? I don't even know where I'm going with this.

32.768 kHz crystal for accurate time keeping. Cell modem with 150MB SIM card from Truphone, so Data transfers has been figured out, with Nano SIM / eSIM card support to buy whatever cell phone plans you got.

I will say that I was somewhat annoyed by the "Zigzag" pins the first time I saw them from Microchip. But I've been sold on it: by zigzaging the pins, the header-pins become easier to solder (!!), because the additional friction holds the pins still during soldering.

It takes more force and effort to jam those pins in, but its worth the effort and an overall easier job when you get used to it.

The ~$70 USD board is on the expensive end, but... cell phone modem !!!! Temperature Sensor, Color Sensor, and Serial EEPROM, etc. etc. Lots of nifty little features for sure.
