Description

I'm sure [your SPI programmer](https://trmm.net/SPI) works great, but for those who do not happen to have a teensy on hand and would end up buying some hardware to flash things anyway, I would recommend picking up a CH341A-based ([datasheet](http://www.datasheetspdf.com/datasheet/CH341A.html)) programmer. These:
- can read & write common SPI & I2C EEPROMs
- can be acquired for ~$3 USD including taxes and shipping (!) [on ebay](http://www.ebay.com/sch/i.html?_nkw=CH341A)
- have a [working open source driver](https://github.com/setarcos/ch341prog) to interface with them
- are decently fast: writes my 8mb ME region in ~100 seconds, reads it in ~60s, erases it in ~25s

SOIC8 clips can also be acquired (w/ tax & shipping!) for about $3 USD [on ebay](http://www.ebay.com/sch/i.html?_nkw=SOIC8+clip).

Research direction

Review the linked SPI programmer recommendation, CH341A datasheet, ch341prog driver, and SOIC8 clip references first. Clarify where this hardware guidance belongs and what project documentation should be updated; done means the recommendation is incorporated in an agreed location with accurate links and usage context.
