The changelog contains all the details of what things we changed from sense_rev3 to sense_rev4.
| S.No. | Sense_rev3 | Sense_rev4 |
|---|---|---|
| 1 | TSM2301 footprint had wrong pin numbers | Updated |
| 2 | RBG LED with different voltage levels that two AA batteries cannot provide | Changed to Dual-LED with 1.9V & 2.1V Forward Voltages |
| 3 | Pogo programmer pin mapping was incorrect | Updated |
| 4 | 0805 passive components took too much space | updated all resistors and capacitors(except for 22uF) to 0603 footprints |
| 5 | all footprints were exact to the dimensions mentioned in datasheets | updated to Hand soldering footprints, which will make soldering better |
| 6 | The gain and low cut-off freq. of Amplifier circuit is not under our control | Introduced Programmable Rheostat to control Gain, and hence the amplification of signal |
| 7 | component placement needed to be optimized | Changed component placement, NO vias used for any signal other than VCC and GND |
| 8 | No test points | Test Points introduced for PIR_OUT, Stage1, and Stage2 of amplification |
