Seeduino AVR library not coming up in arduino ide


I’m only seeing the below options presented in the board manager, but I need the AVR board library for my seeduino nanos. Can anyone tell me what I’m doing wrong?

I’m using the below additional board manager URLS:

I don’t have a Seeeduino Nano, but Seeed says it is the same as an Arduino Nano (Uses ATmega328P and has identical pinout and functions). I do have lots of UNOs and Nanos.

So: under Board->Arduino AVR Boards

Select Arduino Nano.

Let us know if this works for you.

The AVR boards are one of the few sets that come with the Arduino IDE (at least they did for me), and don’t require any additional downloads. (I’m still using Arduino 1.8.6; getting ready to test fly the new 2.0 release that just came out of Beta.)
