Esplog hv: common questions
What microcontroller does the Esplog hv use?
The Esplog hv is built around the ESP32-C3, from the ESP32 family.
How big is the Esplog hv PCB?
The Esplog hv measures 16.6 × 11.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esplog hv?
25 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esplog hv design files?
From the VladimirP1/esplog-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Esplog hv design in my own project?
The repository has no license, so all rights stay with VladimirP1. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esplog hv 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.
