Esp01-flasher: common questions
What microcontroller does the Esp01-flasher use?
The Esp01-flasher is built around the ESP-01v090, from the ESP8266 family.
How big is the Esp01-flasher PCB?
The Esp01-flasher measures 50.8 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp01-flasher?
25 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esp01-flasher design files?
From the nnarain/esp01-flasher repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Esp01-flasher design in my own project?
The repository has no license, so all rights stay with nnarain. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp01-flasher 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.
