PickOMatic V2

PickOMatic V2

Place faster. Place smarter. The open-source motion controller that turns your pick-and-place ambitions into production reality.

PickOMatic V2 is a professional-grade, all-in-one motion control board designed from the ground up for desktop pick-and-place machines. It is the second generation of the PickOMatic motion controller, rebuilt around a modern 32-bit RISC-V microcontroller with native Ethernet and USB-C connectivity.

One board drives the entire machine: gantry, picker heads, nozzles, vacuum, lighting and feedback, with no shields, no breakout spaghetti and no compromises.

Highlights

• RISC-V power : WCH CH32V317VCT6 (QingKe 32-bit RISC-V core, LQFP-100), a massive leap over the 8-bit ATmega2560 of V1
• 7 stepper channels : on-board DRV8825 drivers for the XY gantry, Z axis and auxiliary picker-head axes, each with per-channel microstepping selection (M0/M1/M2 solder jumpers) and current trim
• Ethernet on board : integrated PHY with RJ45 magjack (HR911105A) for fast, reliable G-code streaming over the network
• USB-C : modern connectivity for setup, control and firmware workflows
• Vacuum and pneumatics : dedicated relay outputs (NC-COM-NO) for the vacuum pump and pneumatic accessories
• 3 servo outputs : independent nozzle height / rotation control per picker head
• 5 endstop inputs : dedicated limit-switch inputs for X, Y and Z homing (dual X and dual Y supported)
• Inspection lighting : dedicated LED control output for camera lighting
• Operator feedback : on-board buzzer and status LEDs
• Expansion ready : I²C bus, custom headers, FTDI UART header, SWD debug port and BOOT jumpers
• Clean power architecture : single 12 V input with on-board buck converters (TPS562200) and LDO rails for logic

Getting started

1. Clone the repository

   git clone https://github.com/rmingon/PickOMatic-V2.git

2. Open hardware/hardware.kicad_pro in KiCad (version 8 or later recommended)
3. Review the schematic and PCB, then export Gerbers and the BOM for your fab house
4. Assemble, set the DRV8825 current limits, configure microstepping with the solder jumpers, and connect your motors, endstops, servos and vacuum pump
5. Flash your firmware via SWD or the FTDI/BOOT bootloader path, and start placing parts
