About the Magstock2018 PCB

Magstock2018 is an open source ESP8266 PCB design by cnlohr, published on GitHub. It is a 2-layer board measuring 95.8 × 76.2 mm, with 45 components from 24 distinct parts.

Its main chip is the ESP12E, from the ESP8266 family. Other key parts include the TLV70036 and OPAMP_MCP6001T. By type, the board carries 13 resistors, 9 diodes, 7 capacitors, 6 switches, 5 connectors and 3 ICs.

From the project

1.6mm LEAD-FREE GREEN PCBS The WS2813s have PIN1 pointing DOWN and to the RIGHT. Molex 0.1" Connectors may be replaced with any kind. TLV70036 regulator may be replaced with any 3.6V regulator. D5 (DO-214AB Schottky) Must be at least 20V, and at rated to least 4A. Must be DO-214A

D5 (DO-214AB Schottky) Must be at least 20V, and at rated to least 4A. Must be DO-214AB or similar size. ONLY SOURCE ESP12E from ELECTRODRAGON. TACTILE switches should be full-size tactile switches, used on first MAGFest order. Microphone should be through-hole electret microphone. 3.5mm Barrel Jack should be similar to Digikey P/N CP-3536N-ND. * TLV70036 regulator may be replaced with any 3.6v…

Magstock2018: common questions

What microcontroller does the Magstock2018 use?

The Magstock2018 is built around the ESP12E, from the ESP8266 family.

How big is the Magstock2018 PCB?

The Magstock2018 measures 95.8 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Magstock2018?

45 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Magstock2018 design files?

From the cnlohr/magstock2018 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Magstock2018 design in my own project?

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

Can I test firmware for the Magstock2018 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.
