Esp 12v: common questions

What microcontroller does the Esp 12v use?

The Esp 12v is built around the ESP-01v090, from the ESP8266 family.

How big is the Esp 12v PCB?

The Esp 12v measures 84.1 × 25 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp 12v?

17 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp 12v design files?

From the onkelpit/esp_12v repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp 12v design in my own project?

Yes, under the terms of its GPL-2.0 license, which onkelpit chose for the repository.

Can I test firmware for the Esp 12v 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.
