BIGTREETECH SKR Pico V1.0 Controller Board Perfectly Compatible with Voron V0.1 3D Printer, Fits for Raspberry-Pi Using Klipper Firmware, Entry-Level 4-axis DIY Motherboard

I have 3 of these in custom built delta style 3D printers, so they are not just for Vorons. The small size is perfect and I like that you can stack a Raspberry Pi under or on top. I use these with a Pi zero 2w stacked on top with a cooling fan and have had no issues. This would be my go-to for any basic 3D printer upgrade to Klipper, along with a Raspberry Pi Zero 2w.

Massive upgrade from MKS SBase board to this on Tronxy X5S, allows use of klipper and layout makes setup very easy.

This board is perfect for smaller printers. I'm using it in a custom build with klipper. The footprint matches a pi and the board can also power a pi and communicate with it directly. No USB or external power supply needed. The sideways connectors prevent stress and keep things tidy. Very cool!

My SKR Pico for my Voron V0 just randomly died only a short 4 months after "upgrading" from my SKR 1.2 board. It didn't even have 100 hours of print time on it. The Picos are full of all sorts of issues, just do some Googling to see all the problems with it, including issues with connecting to the MCU, issues with the USB power, issues with the serial connection, and more. I would wait for an updated board if you can. Unfortunately, I have to order a second one of these as I need to get printing, but I really would not recommend this thing as it is now.

Just got this this morning haven’t installed it yet but I love that the pin out is on the back of the box

Have it hooked up using uart very responsive and works great.

For openers, I've been designing and building 3D printers for almost 4 years now... Some Marlin... mostly Klipper. I've had my share of controller boards, but this one remains the one that burned 2 weeks of my time and I couldn't even get it to turn a stepper motor! Add that to the 9 days I waited for a not-very-helpful response from their tech support, and then another 8 days after I immediately responded. Documentation is typical BTT (mostly on Github, and with errors... i.e., the picture of the Pico has the JST connector going into the Dupont, and vice versa). I can only conclude this board has problems, and they probably know about it... so don't expect a response. I'm now 3 days away from the return window so its going back... My advice is to go with a more established board. As nice as this board looks, you'll burn a few weeks pulling your hair out.

I cannot connect to it via Raspberry Pi, I continually get MCU unable to connect errors.
