STM 4MB RAM upgrade. These are difficult to fit as you need to remove the old DRAM and solder the new 4MB board in place. Currently I do not know if the shielding will fit back in place or not.Do not attempt to fit this kit unless you are good at soldering!
PCB has DRAM soldered and SMT parts only. You will need header pins such as item #0158. 4 wires are supplied,colours are random.
