I hope this is the correct place for this post, if not please let me know and I'll move it.
But I'm providing Volt Mod and Repair services for the 5chip Gridseed units to the GTA (Greater Toronto Area)

For repairs generally we need to have a look, damage is typically limited to the USB port being damaged by insertion of the cable.

We use %1 402 size resistors and work is done by a professional Electronics Engineer.
