BIGTREETECH SKR PICO V1.0 Control Board Integrated 4 Axis TMC2209 UART Stepper Motor Driver Compatible with Raspberry Pi Online Printing for Voron V0 V0.1 3D Printer Motherboard

the pico is a great little board when I bought it from amazon they were charging $44.99 I bought one for my Voron V0.1 cause I liked the idea of how easy the pico made UART connections and the board powered the pi then as I was looking for the pinout I saw BTT was selling it for $25.99 sadly amazon doesn't have a price match and I had to return the amazon board (unopened) and at such a great price I bought 3 picos 1 for my V0.1 one for my SW and one for a project I'm planning in the future I do love this board the only complaints I have is one the UART and usb cable are a little on the short side and tow that its hard to find electroincs bays for due to all the ports angled to the side and not straight up but both seem to be done so you can attach a pi on the top of the board but I like doing it side by side anyways both are minor complaints and easily fixed if you need a board for a printer that needs only 4 motor ports you can't go wrong with this one

Flashed GRBLHAL to this controller to run my laser. I use Lightburn. Does a FINE job compared to the A4988 drivers I was using previously. I'm not smart enough to reallocate one of the spare trinamic drivers to run each of my 'y' axis steppers in the firmware build process so I ended up splitting them again from one driver. Worth every penny!

Hard to install, quiet drivers, no display or wifi. Compatible.

This is my favorite 3dp board I've ever used. It's so small. Runs well and having rpi spaced mounting holes is brilliant. This board is missing two things that I hope it gets in the next revision: It needs to replace D16 with a straight connection so sbcs can be powered directly over usb c, and it needs a can transceiver on board. It would also be really nice to have 4pin fan connectors in either 12v or 5v!!!!!

This is probably the cheapest way to upgrade a printer to silent stepper drivers. That said, this is made for Klipper firmware and must be connected to a computer. It was designed for the raspberry pi, and easily connects to it's UART with the included cable. I installed this in an ender 3 with a pi zero w and it works great! It's so quiet now, I can't tell when it's done! The part fan is louder than the motors, now. Sensorless hooking works well, too. Just don't use it for the z axis, as it's not precise enough. I'd give this 5 stars if it came with any documentation whatsoever.
