About the Machine access node PCB

Machine access node is an open source ESP8266 PCB design by leedshackspace, published on GitHub. It is a 2-layer board measuring 76.2 × 69.9 mm, with 32 components from 24 distinct parts.

Its main chip is the WeMos D1 Mini, from the ESP8266 family. Other key parts include the LM7805_TO220, Vigortronix-VTX-214-005-005, RFID-RC522 Reader and 4N25. By type, the board carries 7 resistors, 6 diodes, 5 ICs, 5 connectors, 5 capacitors and 1 transistor.

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

From the project

Hardware interface to the Tool Access API.

Hardware and firmware to provide restricted access to dangerous and delicate tools. Built around an ESP8266 (WeMos D1 mini) and RFID-RC522 breakout.

Designed to be easy to build for all levels of experience - simply order the PCB from DirtyPCBs or OSHPark and solder the through hole parts to the board. Software builds through the Arduino environment and will flash directly to the WeMos board over USB.

Machine access node: common questions

What microcontroller does the Machine access node use?

The Machine access node is built around the WeMos D1 Mini, from the ESP8266 family.

How big is the Machine access node PCB?

The Machine access node measures 76.2 × 69.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Machine access node?

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

Where can I download the Machine access node design files?

From the leedshackspace/machine-access-node repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Machine access node design in my own project?

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

Can I test firmware for the Machine access node 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.
