mohan-bee/rc-link-breakaway-panel
A four-layer RC link panel combining an STM32/E28 2.4‑GHz transmitter with USB-RP2040 socket and an STM32/E28 receiver providing six buffered PWM servo outputs, regulated 3.3‑V power, headers, controls, and protection/decoupling.

# JLCPCB order — keep release files together
Upload `RC-LINK-PANEL-Gerbers.zip`, `BOM.csv` and `CPL.csv` from this release. Do not upload `raw-gerbers.zip`: its automatic assembly drafts are unverified. Older release CSVs are superseded.
- Customer panel, **2 different designs**, 133 × 76 mm; quantity counts panels, each yielding one RX and one TX.
- FR-4, **4 layers**, 1.6 mm, standard **1 oz copper**, green mask, white silkscreen, lead-free HASL or ENIG. Do not substitute 2 oz without another trace/space review.
- Layer order: F_Cu / In1_Cu / In2_Cu / B_Cu. PTH through all layers; keep NPTH file separate.
- Top-side SMT assembly, **75 placements** (33 TX + 42 RX). Upload CPL coordinates unchanged; all files share the same centered origin. Review the factory placement preview and polarity against the assembly view.
- **0.10 mm stencil**; RX MCU thermal pad has four 1.5 mm apertures, about 66% coverage. No paste on fiducials or hand-installed headers.
- Nine routed slots with 2 mm tool-compatible rounded corners; 0.6 mm NPTH mouse bites, 0.85 mm pitch. Ask factory CAM to confirm routed slots, tabs, edge clearances, panel charges and fiducials before payment.
- XIAO RP2040, sockets, SWD and I/O headers, mating crimps/cables and external power hardware are **not included** in the SMT assembly. Order and hand-fit separately.
Component availability and factory CAM/assembly acceptance must be confirmed during the quote. This is a prototype release: successful fabrication checks do not replace powered, thermal, firmware and RF first-article tests. Receiver optional servo rail: 5 V regulated, 2 A total design limit including stalls/transients, >=3 A contacts. See `POWER-AND-WIRING.md`.
