ESP-01 Breakout: common questions
What microcontroller does the ESP-01 Breakout use?
The ESP-01 Breakout is built around the ESP-01v090, from the ESP8266 family.
How big is the ESP-01 Breakout?
The ESP-01 Breakout measures 88.9 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP-01 Breakout?
136 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the ESP-01 Breakout design files?
From the gezepi/ESP-01_Breakout repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ESP-01 Breakout design in my own project?
The repository has no license, so all rights stay with gezepi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP-01 Breakout 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.
