PocketLab Card V1: common questions
What microcontroller does the PocketLab Card V1 use?
The PocketLab Card V1 is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.
How big is the PocketLab Card V1 PCB?
The PocketLab Card V1 measures 85.6 × 54 mm, has 4 copper layers and is 1.2 mm thick.
How many components are on the PocketLab Card V1?
243 components, from 138 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 PocketLab Card V1 design files?
From the Jebroa774/BomberCard repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the PocketLab Card V1 design in my own project?
The repository has no license, so all rights stay with Jebroa774. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PocketLab Card V1 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.
