Connectors (logical): - J1 (LCIN 1x6): [1] E+, [2] E-, [3] S+, [4] S-, [5] SHLD/NC, [6] NC - J2 (SIGOUT 1x4): [1] VOUT, [2] GND, [3] 3V3, [4] VREF (optional — you can remove if unused)
Notes: - Set RG to meet your needed gain: G = 1 + 100k / RG - VREF divider 5.6k/1k from 3.3V gives ~0.5V (bypass with 1uF // 0.1uF) - Do not leave VREF floating. - If your KiCad doesn't have Amplifier_Instrumentation:INA333 symbol, swap it to a…
