Proposing a manufacturability review.

Short answer
  • Can JLCPCB build and assemble it? Potentially yes, but not yet in its current state. Your layout still has DRC errors and your BOM is missing most MPNs, so it isn’t ready for ordering.
  • Total cost with assembly and parts: we can’t quote accurately until we know quantity, assembly options, board size/layers, and all parts’ MPNs. A partial parts subtotal for the major ICs/connectors already specified is about $26.31 per board (see below), excluding all passives and some items.
What blocks manufacturability right now
  • Layout DRC errors: Airwires and an overlapping copper via are present. These must be fixed before fabrication.
  • BOM completeness: 120+ components (most passives) have no manufacturer part number. Without MPNs JLC can’t source or assemble them, and we can’t price them.
  • BGAs present: U1 (361‑TFBGA, 12x12 mm, 0.5 mm periphery / 0.65 mm center pitch per its datasheet) and U2 (96‑ball FBGA, 0.8 mm pitch per its datasheet) are on the design. JLCPCB publicly states they support BGA assembly at 0.5 mm pitch, but 0.5 mm typically requires strict BGA layout rules (often via‑in‑pad with filled/plugged vias) to be manufacturable. Your layout must follow their BGA guidelines.
Partial parts subtotal (LCSC single‑unit reference)
  • These are only the major items that already have MPNs and LCSC pricing visible. All passives, one inductor, Tag‑Connect, and the two DIP switches are not included.

  • Subtotal of items above: $26.31 per board (excludes 58× 0402 caps, 18× 0603 caps, 45× resistors, L1, two DIP switches, Tag‑Connect, and anything without LCSC pricing).
What I need to give you a real “parts + assembly” total
  • Build quantity (pcs).
  • Assembly options: single- or double‑sided placement; consigned vs JLC sourcing; any “extended” parts; stencil type.
  • Board parameters: outline size, layer count, finish, mask color, copper weight.
  • Confirm BGA rules: whether we can use via‑in‑pad with filled/plugged vias if needed for U1.
Recommended next steps to get to a JLC‑ready quote
  1. Fix DRC: resolve all Airwires and the overlapping copper via.
  2. Assign MPNs for all passives to LCSC‑stocked parts (to keep assembly cost low).
  3. Validate BGA fan‑out to JLC’s 0.5 mm BGA guidelines (via‑in‑pad/plugged via strategy if required).
  4. Provide the quantity and assembly parameters above; then I’ll compile a full JLC quote pack and total cost.
If you want, I can pick LCSC equivalents for the passives and run a complete availability/pricing pass, then summarize total parts cost at your target quantity and the expected JLC assembly fees.
