Python driver for GD25Q16C 2MB SPI NOR Flash Memory IC. This part is commonly used to increase MCU flash memory. It typically costs less than $1. This driver was developed for Raspberry Pi. Works on both Python 2 and 3. https://www.gigadevice.com/product/flash/product-series/spi-nor-flash/gd25q16c.html
Why use this device with a RPi? I plan to use it to hold a unique identifier when soldered on development boards. I would like to store rework history of the board in it as well. Data collected using a particular board can be tagged to have the board identifier (just like all the instruments used to collect the data).
