Node Analog: common questions
What microcontroller does the Node Analog use?
The Node Analog is built around the ESP32-C3, from the ESP32 family.
How big is the Node Analog PCB?
The Node Analog measures 83.7 × 53.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Node Analog?
130 components, from 58 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 Node Analog design files?
From the maivananh111/DoAnTotNghiep 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 Node Analog design in my own project?
The repository has no license, so all rights stay with maivananh111. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Node Analog 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.
