ESP32Sensor-Sensor board: common questions
What microcontroller does the ESP32Sensor-Sensor board use?
The ESP32Sensor-Sensor board is built around the OP27GSZ-REEL7, from the ESP32 family.
How big is the ESP32Sensor-Sensor board?
The ESP32Sensor-Sensor board measures 38 × 60 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ESP32Sensor-Sensor board?
86 components, from 64 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the ESP32Sensor-Sensor board design files?
From the LESA-RPI/hfs.main repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the ESP32Sensor-Sensor board design in my own project?
The repository has no license, so all rights stay with LESA-RPI. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP32Sensor-Sensor board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
