ESPlant - Environment Sensor Plant =============

Welcome to the linux.conf.au Open Hardware Project. You can see information about this and other MiniConfs at http://www.openhardwareconf.org/wiki/Main_Page

The ESPlant kit is designed to provide an open source platform to transmit environmental data to a central source using the power of wifi.

The KiCad project lives in the CCHS-Melbourne/ESPlant repository on GitHub; these links point at the commit this page was built from.

ESPlant: common questions

What microcontroller does the ESPlant use?

The ESPlant is built around the ESP-12E, from the ESP8266 family.

How big is the ESPlant PCB?

The ESPlant measures 97 × 77.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESPlant?

75 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESPlant design files?

From the CCHS-Melbourne/ESPlant repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESPlant design in my own project?

Yes, under the terms of its TAPR-OHL-1.0 license, which CCHS-Melbourne chose for the repository.

Can I test firmware for the ESPlant 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.
