The Seeeduino Nano is a compact board similar to the Seeeduino V4.2/Arduino UNO, and it is fully compatible with Arduino Nano on pinout and sizes. Compared to the Arduino Nano, the Seeeduino Nano use USB-C instead of Mini-USB, which is symmetrical and reversible.
Just like the Seeedunio V4.2, Seeeduino Nano is built around the Atmega328P 8-bit AVR microcontroller. So you can use the same program code on both boards. However, the dimensions of the two are significantly different. Less than a quarter of the size, but with almost the same features, Seeeduino Nano will save more space for your project, more suitable for space-constrained projects.
