ToTheEdge,LCSCNums Moved the 3.5mm connectors to the edge and edited their footprint courtyard so no errors. Adjusted the planes so that it bordered 3.5mm connector pads well and didn't go to edge cuts. Added LCSC part numbers to the parts that were in stock.

finished majority of layout, pcb expanded to four copper layers to accomadate power planes

first chunk of pcb layout and schematics mods (no connects on pins and changing global labels to hieracarchical labels), one filtering pcb circuit layed out

updated GND symbols for appropriate seperatiion of analog and digital grounds

Reference Designator and Footprint Updates Changed almost all reference designators to group similar components by what filter they are a part of and what value they have. Need to: - Sort symbol data for ADC and OpAmps to correct folders - get footprint files for ADC and OpAmps

added audio jack connectors for emg connections

removed sda scl pullups, removed electrode connectors to make space for proper connectors later

added connectors for electrode inputs and revamped battery connectors

Filter abstraction and Input output connectors Abstracted filters so there are 4 signal paths to go to ADC. Added input and output connectors.

swapped lpf and hpf in bandpass filter and added testpoints on various filter circuits
