EmbeddedSystemKit: common questions
What microcontroller does the EmbeddedSystemKit use?
The EmbeddedSystemKit is built around the C2797196, from the ESP32 family.
How big is the EmbeddedSystemKit PCB?
The EmbeddedSystemKit measures 123.3 × 61 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the EmbeddedSystemKit?
73 components, from 46 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 EmbeddedSystemKit design files?
From the bostang/PCBs 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 EmbeddedSystemKit design in my own project?
The repository has no license, so all rights stay with bostang. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the EmbeddedSystemKit 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.
