Microcontroller Schematics: common questions
What microcontroller does the Microcontroller Schematics use?
The Microcontroller Schematics is built around the TSR_1-2450, from the ESP32 family.
How big is the Microcontroller Schematics PCB?
The Microcontroller Schematics measures 79.4 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Microcontroller Schematics?
49 components, from 40 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 Microcontroller Schematics design files?
From the AlexFinns/TELEMETRY_ISH_Greenpower 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 Microcontroller Schematics design in my own project?
The repository has no license, so all rights stay with AlexFinns. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Microcontroller Schematics 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.
