Creating a pick and place control board with the RP2040 #RaspberryPi #RP2040 @theavalkyrie
Thea Flowers explores the hardware design of Starfish, her new control board for a pick and place machine built around the Raspberry Pi RP2040 microcontroller and Trinamic TMC2209 motor drivers.
This control board shares some similarities with 3D printer control boards but it has some unique problems to solve- including controlling solenoids and talking to vacuum sensors. I’ll take you through the background, schematics, and layout, along with the decisions made. Starfish is open source, so you can check out the original source files on GitHub.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
