OLD ENGG3800-g15: common questions
What microcontroller does the OLD ENGG3800-g15 use?
The OLD ENGG3800-g15 is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the OLD ENGG3800-g15 PCB?
The OLD ENGG3800-g15 measures 127.2 × 117 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the OLD ENGG3800-g15?
205 components, from 68 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 OLD ENGG3800-g15 design files?
From the JoshCrouch/ENGG3800-HW repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the OLD ENGG3800-g15 design in my own project?
The repository has no license, so all rights stay with JoshCrouch. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the OLD ENGG3800-g15 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.
