Esp03-usb jtag: common questions

What microcontroller does the Esp03-usb jtag use?

The Esp03-usb jtag is built around the ESP8266-ESP03, from the ESP8266 family.

How big is the Esp03-usb jtag PCB?

The Esp03-usb jtag measures 97.8 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp03-usb jtag?

58 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp03-usb jtag design files?

From the jcmvbkbc/esp03-breakout repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp03-usb jtag design in my own project?

The repository has no license, so all rights stay with jcmvbkbc. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp03-usb jtag without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
