About the Sodastream power mod PCB

Sodastream power mod is an open source ESP8266 PCB design by gschwaer, published on GitHub under the Unlicense license. It is a 2-layer board measuring 78 × 46.3 mm, with 43 components from 20 distinct parts.

Its main chip is the ESP-12E, from the ESP8266 family. Other key parts include the Si7205-B-00-IV, PCF8574, TPS22810DBVR and AMS1117-3.3. By type, the board carries 17 resistors, 8 capacitors, 6 ICs, 4 connectors, 3 switches and 3 diodes.

It belongs with the iot & wireless designs in this gallery.

From the project

Because the Internet of Things needed a smart soda maker.

There is (or was) a soda maker called "SodaStream Power". It has some buttons and LEDs and uses a servo to do the usual pushing motion that soda makers require. Mine was broken probably due to an unfortunate design decision (and me). So I thought: If I have to fix it by replacing the MCU either way, why not use a WIFI-enabled one? So I build a replacement PCB with an ESP8266. It even runs python! 😲

Sodastream power mod: common questions

What microcontroller does the Sodastream power mod use?

The Sodastream power mod is built around the ESP-12E, from the ESP8266 family.

How big is the Sodastream power mod PCB?

The Sodastream power mod measures 78 × 46.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sodastream power mod?

43 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sodastream power mod design files?

From the gschwaer/sodastream-power-mod repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Sodastream power mod design in my own project?

Yes, under the terms of its Unlicense license, which gschwaer chose for the repository.

Can I test firmware for the Sodastream power mod 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.
