- Dimensions
- 45 × 18 mm, 5 g[1]
- Upload limits
- 47.5 KB flash, 6 KB RAM[4]
Upload limits are what a sketch or firmware may use after the bootloader, as the build tools enforce them, not the chip’s full memory.
Can I still use it?

History and use today
History
Released in 2019 as the low-cost successor to the Nano, keeping its pinout and 5 V logic.[1]
Still useful for
A drop-in upgrade for Nano projects that ran out of RAM.
