About the Pipette tool PCB

Pipette tool is an open source AVR/Arduino PCB design by rodrigue-laboratory, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 56 × 81.5 mm, with 38 components from 23 distinct parts.

Its main chip is the arduino_mkrzero, from the AVR/Arduino family. Other key parts include the LM7805_TO263, MAX14840EASA+, TMC2208, SN74LV1T125DBVR and uart_tll_to_rs485. By type, the board carries 10 diodes, 10 resistors, 7 ICs, 6 capacitors, 4 connectors and 1 switch.

It belongs with the robotics & motion designs in this gallery.

From the project

1. Install KiCad 7 or newer. 2. Open pipettetool.pro (or the .kicadpro if updated). 3. Inspect the schematic (.sch) and layout (.kicadpcb`). 4. Run ERC/DRC before modifications.

Pipette tool: common questions

What microcontroller does the Pipette tool use?

The Pipette tool is built around the arduino_mkrzero, from the AVR/Arduino family.

How big is the Pipette tool PCB?

The Pipette tool measures 56 × 81.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pipette tool?

38 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pipette tool design files?

From the rodrigue-laboratory/pipette-tool-pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pipette tool design in my own project?

Yes, under the terms of its BSD-3-Clause license, which rodrigue-laboratory chose for the repository.

Can I test firmware for the Pipette tool without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
