[SOLVED] Red light flashes next to barrel-port
#14
From the schematic and data sheet, if thermistor is right,
between FB (14) and GRD (25) should be 2.1V, or 2.05 if a bit hot or 2.025 if hot
And, obviously R53 should be roughly 10K, depending on temp, so 5-12K
GRD is not a pin, the foil under chip, any good grd will do I think (or pin 23)
