LED Blinker Circuit Design

flux

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:
  • Telemetry Port 1
  • Telemetry Port 2
Each port can expose:
  • 3.3V or 5V power
  • GND
  • UART TX
  • UART RX
  • Optional enable/reset
  • Optional SPI pins if you want LoRa modules that use SPI instead of UART
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:
  1. Remove onboard telemetry radio modules and SMA antenna connectors.
  2. Add two compact telemetry connectors.
  3. Wire both connectors to the MCU for redundant telemetry.
  4. Re-place on the 70 × 100 mm board.
  5. Route after placement is clean.
Ready when you are.

Add two compact telemetry connectors for UART redundancy.

flux

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.
