This decoder interprets the digital output of cheap generic calipers
|
||
|
|
(usually made in China), and shows the measured value in millimeters
|
||
|
|
or inches.
|
||
|
|
|
||
|
|
Notice that these devices often communicate on voltage levels below
|
||
|
|
3.3V and may require additional circuitry to capture the signal.
|
||
|
|
|
||
|
|
This decoder does not work for calipers using the Digimatic protocol
|
||
|
|
(eg. Mitutoyo and similar brands).
