PDA: common questions

What microcontroller does the PDA use?

The PDA is built around the 5407-ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the PDA PCB?

The PDA measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PDA?

15 components, from 11 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 PDA design files?

From the jacobjuneau6/PDA 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 PDA design in my own project?

Yes, under the terms of its MIT license, which jacobjuneau6 chose for the repository.

Can I test firmware for the PDA 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.
