TemperatureLogger ESP-12F: common questions

What microcontroller does the TemperatureLogger ESP-12F use?

The TemperatureLogger ESP-12F is built around the ESP-12F, from the ESP8266 family.

How big is the TemperatureLogger ESP-12F PCB?

The TemperatureLogger ESP-12F measures 43.7 × 44.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TemperatureLogger ESP-12F?

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

Where can I download the TemperatureLogger ESP-12F design files?

From the CindyPotvin/TemperatureLogger_ESP-12F repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TemperatureLogger ESP-12F design in my own project?

Yes, under the terms of its MIT license, which CindyPotvin chose for the repository.

Can I test firmware for the TemperatureLogger ESP-12F 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.
