The Memory Plug is a small board which will accommodate up to 4 STMicroelectronics M24M01 EEPROM memory chips. Each chip has 128K byte of memory, with a total potential storage of four chips or 512K bytes of memory. An I2C bus running at 3.3V is used as interconnect, with all the power and signal lines brought out to to both sides of the board to allow daisy-chaining with other I2C-conformant boards.
The Assembled Memory Plug comes with the SMD-sized M24M01 flash memory chips (i.e. 1 for 128K byte, 2 for 256K byte, etc…) populated and the decoupling capacitor already soldered onto the board. Headers for this and all other JeeLabs plugs can be found here (straight) and here (right angle).
The PCB only version is available for those wishing to populate their own boards, and contains just the board for the Memory Plug. No parts, no headers.
