About the Rhizomatic sublime PCB

Rhizomatic sublime is an open source ESP8266 PCB design by maxwolfs, published on GitHub. It is a 2-layer board measuring 85.6 × 54 mm, with 48 components from 31 distinct parts.

Its main chip is the ESP8266EX, from the ESP8266 family. Other key parts include the LTC3225, TPS61221DCKR and AT25SF041-SSHD-B. By type, the board carries 15 resistors, 14 capacitors, 7 connectors, 5 diodes, 4 ICs and 1 crystal.

From the project

Becoming a manifesto

We object to the mundane paradigm of Human-Computer-Interaction and demand a Human-Human-Interaction. It's pyhsicial, it's intimate, it's exciting. Rhizm is a device in the shape of a credit card that connects over a satisfying magnetic click. Caution: Hands may touch. The connection of two cards creates a new bond in a decentralized social mesh network. Combined with a web interface that shows the verified encrypted interactions, Rhizm can be used for many different scenarios in which a physicial interaction between nodes must be safe. Or appealing. We understand our project as fundamental…

Rhizomatic sublime: common questions

What microcontroller does the Rhizomatic sublime use?

The Rhizomatic sublime is built around the ESP8266EX, from the ESP8266 family.

How big is the Rhizomatic sublime PCB?

The Rhizomatic sublime measures 85.6 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rhizomatic sublime?

48 components, from 31 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 Rhizomatic sublime design files?

From the maxwolfs/rhizomatic-sublime repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Rhizomatic sublime design in my own project?

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

Can I test firmware for the Rhizomatic sublime 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.
