Ok, we’ll come clean. [Design Build Destroy] didn’t really add any memory to his Arduino Nano. But he did get about 1.5K more program space when compared to the stock setup. The trick?

I couldn't find complete examples that showed me how to initialize, modify, and write flash memory on the Arduino Nano BLE boards, so I've put this together to capture what I came up with, and ...

The Arduino Nano is powered by an Atmel ATmega328. It's an 8-bit AVR microcontroller that operates at a clock speed of 16 MHz and comes with 2 KB SRAM, 1 KB EEPROM, and 32 KB flash memory.

If like me you enjoy using the range of Arduino development ... At the heart of the Nano 33 BLE Rev2 is the nRF52840 microcontroller, which comes with 1MB of CPU Flash Memory.
