Pcb power usb: common questions

What microcontroller does the Pcb power usb use?

The Pcb power usb is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Pcb power usb?

The Pcb power usb measures 95.8 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb power usb?

52 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb power usb design files?

From the angelnu/esphome repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pcb power usb design in my own project?

Yes, under the terms of its Apache-2.0 license, which angelnu chose for the repository.

Can I test firmware for the Pcb power usb 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.
