Sidbit08/ABEX_PCB_v11A custom ESP32-S3-based PCB designed in KiCad for automated soil sample analysis, featuring drivers and interfaces for environmental sensors, peristaltic pumps, and auger drilling actuators.
Sciencepcb is an open-source printed circuit board by Sidbit08, from the Sidbit08/ABEX_PCB_v1 repository on GitHub. It is a 2-layer board of 126.2 × 143.6 mm with 100 parts on 89 nets, routed with 344 tracks and 27 vias.
It is built around the ESP32-S3-DEVKITC-1-N8R2, BME280 and DHT22, with the DS18B20, AO3400A and SRA-05VDC-CL among its other parts. Its parts include 25 resistors, 24 diodes, 21 connectors, 8 transistors and 8 switches. It belongs with the ESP32 boards of this library.
science_updated.kicad_pcb and science_updated.kicad_pro were included alongside the main Sciencepcb.* project in the source archive. No matching science_updated.kicad_sch was supplied. Their archive timestamps are older than the main board, but timestamps alone do not establish design authority.
Retained unchanged for comparison. The repository entry point is ../project/Sciencepcb.kicad_pro. Do not mix fabrication outputs from these boards without confirming the revision.
