About the Ganimede.E12 HW PCB

Ganimede.E12 HW is an open source ESP8266 PCB design by ffich, published on GitHub. It is a 2-layer board measuring 35.6 × 85.7 mm, with 33 components from 20 distinct parts.

Its main chip is the ESP-12F, from the ESP8266 family. Other key parts include the SPX3819M5-L-3-3 and CH340G. By type, the board carries 15 resistors, 9 capacitors, 3 ICs, 2 switches, 2 LEDs and 1 crystal.

It belongs with the iot & wireless, displays & leds and dev boards & breakouts designs in this gallery.

From the project

Public repo for ganimede.E12 hardware project.

1. It's based on ESP SoC with integrated peripherals like WiFi, BT and USB. 2. It carries some sockets/connectors that allow to use well known standards (Mikroe MikroBUS, SeedStudio grove, others), so no more messy connections with sensor/actuators around your desk. 3. Can be programmed in C/C++, Python and Javascript. 4. It's really cheap. 5. It's open hardware, I will share schematics and design files. 6. It's really simple to use.

Ganimede.E12 HW: common questions

What microcontroller does the Ganimede.E12 HW use?

The Ganimede.E12 HW is built around the ESP-12F, from the ESP8266 family.

How big is the Ganimede.E12 HW PCB?

The Ganimede.E12 HW measures 35.6 × 85.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ganimede.E12 HW?

33 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ganimede.E12 HW design files?

From the ffich/Ganimede.E12_HW repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Ganimede.E12 HW design in my own project?

The repository has no license, so all rights stay with ffich. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ganimede.E12 HW 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.
