This board contains two current shunts and their accompanying amplifiers - part of an attempt to investigate building flexible and intelligent stepper-motor drivers. U1 and U2 are TI INA282 (or equivalent, depending on desired gain) current shunt monitors, C1 and C2 are 0603 0.1uF 16V X7R, and the two four-terminal resistors are Vishay’s WSL3637 series. Operates on a 3.3V supply, with a max common-mode voltage of 80V. Untested, order at your own risk.
