So far running flawlessly on two printers. The board is really easy to configure, as there are countless configs online to get you started. Review: Somehow… Magically….. All my issues were solved - Summary: Great motherboard, just make sure you have a connector for you hotend fan if installing in an ender 3 v2 Review and experience: I bought this after I had kinda given up on the printer. Beforehand I had a setup where it was a Ender 3 v2 with a cr touch, dragonfly hotend, raspberry pi 4B (for klipper), orbiter v2, and dragonfly hotend. I got this on a Black Friday deal and decided to install it on my printer. I will admit setup was a bit difficult because I had to redo the configuration files in klipper and get all the driver settings correct but after that I have been tuning it and it works wonderfully. I previously had issues with my orbiter v2 with the old creality 4.2.7 board even though I had tuned the vref on it and got the multimeter out to make sure it was correct. But after switching to this board and putting in the driver settings I haven’t had an issue with it since. The only thing I didn’t like about the board is the way the hotend fan gets plugged in but that just was because I had an ender 3 v2 that didn’t have the connector on the fan already. Other than that I would give it a 11/10 because it was easy to set up, easy to use, and overall improved my printer by leaps and bounds. ## Features - Main Control Chip: BIGTREETECH SKR Mini E3 V3.0 32 bit control board adoptes the G0 series MCU-STM32G0B1RET6 or STM32G0B0RET6 ARM Coretex. integrated TMC2209 Silent stepper motor drive.

I'm using just about every feature it has, and I've even managed to get CAN bus working on it with the help of a $5 CAN transceiver. I have only a couple of small complaints. First, mine has not been especially quiet, with at least one driver producing a sort of hiss. It's not terribly loud, but it's not silent either. The second issue is that it doesn't have any way to enter DFU mode (Device Firmware Update). This means that if you make a mistake updating the firmware, you may find yourself unable to get the board to boot and unable to write the firmware via USB or an SD card to recover. In my case, I had to purchase a $10 ST-Link V2 programmer to recover from a failed CAN firmware update. Most 3D printer devices with an STM chip have DFU mode, and it would be a relatively simple addition for Bigtreetech to include in this board. Not a deal breaker, but approach firmware updates with caution. ## Frequently Bought Together - BIGTREETECH SKR Mini E3 V3.0 32 Bit Control Board Integrated TMC2209 UART Stepper Driver Supports Marlin/Klipper Compatible Ender 3/Ender 3 Pro/Ender 3 V2 Ender 5 3D Printer Motherboard - BIGTREETECH HDMI5 V1.2 Touchscreen Monitor 5 inch IPS LCD Display 800×480 for Raspberry-Pi 4B/3B, BTT Pi V1.2/Pi 2 Compatible with SKR Mini E3 V3.0/Octopus/Manta M4P/M5P SKR 3 to Running Klipper - BIGTREETECH Pi Control Board 64bit Quad Core, 1GB DDR3L 40-pin GPIO Compatible with SKR Mini E3 V3.0/Octopus V1.1/Pro, SKR V1.4 Turbo/Kraken/SKR 3 to Run Klipper --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/391652178-bigtreetech-skr-mini-e3-v3-0-32-bit-control-board](https://www.desertcart.co.uk/products/391652178-bigtreetech-skr-mini-e3-v3-0-32-bit-control-board) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-04*
