Comes apart quite easily . Seems to have 2 separate smps , one for the
electronics proper and one for the lamp only.
Of the 15 lines 11 go to 3K3 pullup Rs , presumably for key matrix.
Of the remaining 4 , one is gnd, one is clock line of an I2C 24C08, one to
its data line and one to its Vcc
So what sort of thing goes in the missing control panel, like a car radio
removable control panel, linked to those 4 lines?
