BTT SB2209 USB – Compact Toolhead Board for Klipper

The Bigtreetech SB2209 USB (RP2040) is a compact and reliable toolhead board designed for Klipper-based 3D printers, especially Voron V2.4, Trident, or custom CoreXY builds. Based on the Raspberry Pi RP2040 microcontroller, it provides powerful, low-latency communication and supports direct USB connection to the host system — ideal for setups without CAN bus.

🔧 Key Features

MCU: Raspberry Pi RP2040 dual-core processor @ 133 MHz

Connectivity: USB-C interface (no CAN bus required)

Stepper Driver: 1x TMC2209 integrated (UART mode, up to 2A RMS)

Temperature Inputs: 2x thermistor ports (100K NTC supported)

Fan Outputs:

1x controllable fan output (up to 24V, PWM)

1x always-on fan output

Heater Output: 1x hotend heater (up to 60W at 24V)

Probe Input: Dedicated input for Z probe (including inductive sensors)

Endstops: X and Y endstop inputs

LED Output: Neopixel (WS2812) port for addressable RGB LEDs

Power Input: 24V via VIN or USB only for logic

📦 Typical Use Case

Toolhead board for Voron printers using USB communication instead of CAN

Works well with Stealthburner or Clockwork 2 setups

Simplifies wiring by centralizing toolhead electronics into one board

📐 Dimensions and Mounting

Board Size: 45mm x 40mm

Mounting: Compatible with standard Stealthburner rear mounts

Cooling: Passive (no heatsink needed for typical use) shop.zen3d.eu – BTT SB2209 USB Toolhead Board

Ernie (L) has a fault on the neopixels and Bert (R) needs a fan swapping out on the Pi running octoprint but both are chugging happily away doing prototyping for @theatreinthemill tonight. #3dprinting #filamentive @filamentive #crealityender3 #crealityender5pro #bigtreetech https://www.instagram.com/p/CSxPns2M7LJ/?utm_medium=tumblr

Finally got the hot end #neopixels working. They run open white during printing for illumination but then switch to other colours to indicate printer status. Still slightly overshadowed by the bling new 80mm PSU fan and enclosure. I’m very pleased with how this worked so well on the new satsana duct. Just waiting on quiet fans arriving on the slow boat from China. #ender3 #marlinfirmware #crealityender3 #bigtreetech #skrminie3v2 https://www.instagram.com/p/CHu-WWkHfo3/?igshid=3xiumx1kpchh

Nerve wracking few hours last night but the SKR Mini E3 v2.0 board is installed, the latest Marlin v2.0 is compiled and flashed and the BLTouch autolevelling sensor works perfectly. My Ender3 has levelled up! (As have my tinkering skills). #ender3 #bigtreetech #creality3d https://www.instagram.com/p/CFjZGojnr2W/?igshid=1wf5tlmr8ck9f
