## Article

**INTRODUCTION**

This board is for small 3D printer/CNC with network connectivity and size is 82 x 60 mm

**FEATURES**

- 4 Stepper motor divers

- 2/3 Analog inputs (depending on network connectivity)

- Analog or digital Z-probe support

- 1 heated bed, 1 extruder, 1 fan control

- Micro SD-card

- I2C and I2S expansion ports

- USB 2.0 interface

- 4 End-stops including end-stops via current measuring on every stepper motor driver

- Network connectivity: Ethernet (W5500 module) or WiFi (ESP8266)

- 2 layer board, inexpensive to order (it might require applying additional solder on some power tracks and vias depending on desired current requirements)

- Firmware: RepRap, Klippe

**TECHNICAL DETAILS**

The firmware of this project use RepRap, Klipper. RepRap is started in [England](https://en.wikipedia.org/wiki/England) in 2005 as a [University of Bath](https://en.wikipedia.org/wiki/University_of_Bath) initiative to develop a low-cost [3D printer](https://en.wikipedia.org/wiki/3D_printer) that can print most of its own components, but it is now made up of hundreds of collaborators worldwide.[\[1\]](https://en.wikipedia.org/wiki/RepRap_project#cite_note-Jones,_R._2011-1) RepRap is short for rep*licating* rap*id prototyper*. The Klipper is a 3D-printer firmware. It combines the power of a genernal purpose computer with one or more micro-controllers
