ProcessingAndStorage: common questions
What microcontroller does the ProcessingAndStorage use?
The ProcessingAndStorage is built around the ESP32-WROOM-32E, from the ESP32 family.
How big is the ProcessingAndStorage PCB?
The ProcessingAndStorage measures 85 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ProcessingAndStorage?
50 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the ProcessingAndStorage design files?
From the RobertGawron/HardwareDataLogger repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ProcessingAndStorage design in my own project?
Yes, under the terms of its MIT license, which RobertGawron chose for the repository.
Can I test firmware for the ProcessingAndStorage 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.
