SKR 3 EZ is feature loaded and should be your next upgrade! - There is a lot to say about this board as I have been a BTT supporter for awhile with their SKR Mini e3 boards as well as their TFT screens. Since this was not as "plug and play" there were some learning curves, but nothing that was very difficult to figure out. Here are some of my highlights and lowlights from my experience with this board Pros: EZ Drivers: It's in the name. These are literally just plug in and they work. No more moving pins or plugging things in backwards. They go in one way and make driver installation completely fool proof. The TMC2209 drivers do allow for sensor less homing, but I chose not to enable that on this board and just use endstops and firmware limits for my bed size. They are completely silent so you don't have to worry about any noise coming from the printer which is as to be suspected with the TMC2209s. This board also has 5 independent drivers so you can run G34 Auto Align on your dual lead screws which is a gamechanger for leveling and accuracy. Fan Control: 3 controllable fans on this board is a great option so you don't always have to have fans running when the printer is idle. All my fans are 24v so there was no need for me to utilize the different voltage but having that option is very welcome! Control Board: 32-bit ARM Cortex-M7 board is almost overkill, but that's fine by me. For my needs, it will never have any issues and will process whatever, whenever I need it to. CONS Firmware: If you are not familiar with compiling your own firmware, you will not find precompiled versions for this board as readily available as you may think. I'm sure over time there will be plenty out there but if you are not comfortable creating your own firmware you may want to do a little research or be prepared to learn. This is not as plug and play as the SKR Mini E3 boards. Quality Control: I don't know where to put this one, but the first board I received was clearly a board that was returned by someone. There were no cables, no duck, and multiple drivers were loose in the box. At first, I thought that I had enough cables and ducks so it wasn't a big deal but after wiring the board up, it didn't work whatsoever. I triple checked the pinouts, did my diagnostics and got NOTHING. After going back and forth with customer service to no avail, I just returned it for a new board. The replacement worked perfectly wired the exact same way and it came with all the products I was expecting. Thankfully I bought this on desertcart and could return it. This was concerning since I bought this through BIGTREETECH's desertcart store but I guess they are sending out possibly returned product as new which is concerning. Overall, the board itself is GREAT and I would recommend it to anyone looking to get some additional features and possibly run Klipper, Sensorless Homing, or Dual Z Leads. I can overlook the initial product issue since it was taken care of, but I didn't like that returned product was being shipped for new orders. This needs to be resolved so the same thing doesn't happen in the future. I still am a BTT fan overall because the product speaks for itself at the end of the day! Review: Excellent board - I used this board as part of a general reconstruction of my Ender 5 Plus. I had no problems at all integrating it with the existing sensors, heaters, motors, etc., and configuring it to use Klipper firmware with the existing hardware also went perfectly smoothly. Highly recommended as an upgrade or for built-from-scratch printers! ## Features - Why use EZ Drivers? Because 40% of users have damaged the driver due to the wrong installation. It will damage the control board or even more damage. Using EZ Drivers can improve the experience of more users - SKR 3 EZ 3D Control Board adopts two kinds of driver sockets, which are compatible with both BIGTREETECH EZ series driver modules and TMC series driver modules. Each motor drive module can select the corresponding motor voltage through the jumper cap - SKR 3 EZ mainboard using 32-bit ARM Cortex-M7 series STM32H723VGT6 main control chip with a main frequency of 480MHz, the performance has greatly improved. It reserves the BOOT button, users can update the motherboard boot program through DFU - SKR 3 EZ’s numerical control fan realizes 24V, 12V, 5V voltage selection through the external power supply module, eliminating the need for the operation of the customer's external transformer module, thereby reducing the probability of damage to the motherboard - EZ Drivers can achieve quietness when the motor is locked and running at low speed. It is recommended to select when the maximum motor speed is lower than 300RPM; it can achieve quietness and low power consumption in a wide range of speed and torque. It is recommended that the maximum motor speed exceeds 300RPM Select at 300RPM ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B1WQ9B8L | | Best Sellers Rank | #81,132 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #39 in 3D Printer Controllers | | Brand Name | BIGTREETECH | | Color | Black | | Customer Reviews | 3.9 3.9 out of 5 stars (58) | | Display Type | LCD | | Included Components | BIGTREETECH SKR 3 EZ + 5PCS EZ2209 | | Manufacturer | BIGTREETECH | | Material Type | PCB | ## Product Details - **Brand:** BIGTREETECH - **Color:** Black - **Display Type:** LCD - **Manufacturer:** BIGTREETECH - **Material:** PCB ## Images ![BIGTREETECH SKR 3 EZ Control Board 32bit New Upgrade Silent Board Support EZ2209/ EZ5160/ EZ2130 Stepper Driver Compatible TFT Series Touch Screen, DIY for Most FDM 3D Printer (with 5PCS EZ2209) - Image 1](https://m.media-amazon.com/images/I/81zlUgNoA7L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ EZ Drivers are a great innovation.

I had no problems at all integrating it with the existing sensors, heaters, motors, etc., and configuring it to use Klipper firmware with the existing hardware also went perfectly smoothly. Highly recommended as an upgrade or for built-from-scratch printers! ### ⭐ Klipper - USB communication failure *by R***. on March 20, 2026* Bought this for upgrade of my 8 bit Klipper MCU. Unfortunately, I did not see the many failure reports. Mine would not initialize the USB connection for the Klipper firmware even though I followed the BTT instructions to the letter. Very disappointed!!! Returning for a refund, and will think twice before buying other BTT products. Update: I decided to burn a little more time with this before returning it. and have learned a few things trying to make it work as a Klipper MCU: 1. The documentation is grossly incorrect for the EZ version of this board. - Pin mapping is a mess. 2. The CPU is a 723, not the documented 743. 3. The standard SD card bootloader would not allow Klipper firmware to run properly, which meant no USB communication. Had to load the Klipper firmware in DFU mode, wiping the standard bootloader. 4. In order to make this work with 6 motors (X, Y, Z, Z1, E, Y1), the two Z connectors are hardwired to operate in parallel. 5. Some if the I/O is shared between various interfaces which means that some of the "normal" connections are useless. Running 5 motors will mean that either the Hotend or the bed heater (HE0 or HB) needs an additional high current driver triggered off one of the CNC fan ports. In addition to this only two of the CNC fan ports are available, so you get one for a heater and another for a filament cooler. Want a second extruder on this configuration? Forget it. There is more but that's all I can remember at the moment. In the end I think I have what I need running, but not fully setup yet, and no room for any future expansion. ## Frequently Bought Together - BIGTREETECH SKR 3 EZ Control Board 32bit New Upgrade Silent Board Support EZ2209/ EZ5160/ EZ2130 Stepper Driver Compatible TFT Series Touch Screen, DIY for Most FDM 3D Printer (with 5PCS EZ2209) - BIGTREETECH TFT35 E3 V3.0.1 Graphic Smart Display Panel Board for Ender-3 Compatible with SKR Mini E3 V3.0, SKR 3/EZ, Octopus/Pro/Max EZ, Kraken, SKR Pro V1.2 Control Board - BIGTREETECH TMC2209 V1.3 Stepper Motor Driver with Heatsinks 5 Pack, Silent Stepsticks Drivers, UART/Step/DIR Mode, Replace A4988, for SKR 3/SKR V1.4 Turbo/Octopus V1.1/Octopus pro/Manta M4P/M5P/M8P --- ## 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.com.ar/products/446446214-bigtreetech-skr-3-ez-control-board-32bit-new-upgrade-silent](https://www.desertcart.com.ar/products/446446214-bigtreetech-skr-3-ez-control-board-32bit-new-upgrade-silent) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
