Yes — that makes sense, and it will help the board fit.

Instead of building telemetry radios onto the PCB, we can make the board provide two telemetry connector ports for redundancy:

Each port can expose:

That means I should remove the onboard telemetry modules and SMA antenna connectors, then replace them with two compact external telemetry headers. This will reduce board area a lot because the placement issue is driven mostly by the bulky modules/connectors, not by component count. The connector-replacement workflow requires preserving the old nets, replacing the parts, then rewiring the new connector pins to the same functions so the design stays electrically valid . For placement, the board should then be re-placed after resizing because the placement tool works inside the current board outline and cannot resize the board itself .

Recommended next move:

Ready when you are.

I added the two compact external UART telemetry connectors and removed the onboard telemetry radios/antenna connectors. The schematic ERC is clean, the board is still 70 × 100 mm, includes the corner mounting holes and ZEN, and the placement now fits/routs cleanly enough to start routing.

Routing was started, but the job paused because the account ran out of credits. Remaining work: add credits, rerun routing, then review/fix any remaining airwires or layout issues.
