Project Idea Start


That is most likely the WEMOS LOLIN32 V1.0.0, which is different from the 38-pin ESP32 DevKit currently shown in the schematic. Before I replace it, please confirm: does your board have 13 pins on each side and a small white LiPo battery connector near the USB socket?
no it has 18 on 1 side and 14 at another
That pin count doesn’t match the standard WEMOS LOLIN32 or ESP32 DevKit footprints, so I shouldn’t guess the socket geometry. Please upload a clear photo of the front and back of the board beside a ruler, or send its exact product link.

That identifies it: it’s a WEMOS D1 R32 V1.0.0, an Arduino Uno-form-factor ESP32 board. I’ll update the carrier design to use its shield-header pinout and mechanical pattern.
The photos confirm your board is a WEMOS D1 R32 V1.0.0, using the Arduino Uno-style shield connector layout—not the current 38-pin ESP32 DevKit footprint.
The existing sensor-carrier schematic remains intact. The following update is still pending because no ACUs are currently available:
  • Replace the ESP32 DevKit interface with D1 R32 shield headers
  • Verify and remap the sensor GPIO connections
  • Apply the Arduino Uno R3 mechanical header pattern
  • Update the specification, firmware, and bring-up files
  • Re-run ERC/connectivity checks
No partial replacement was made, so the current schematic has not been left broken.
