Large Tree Tech’s SKR Pico Is a Compact Management Board for 3D Printers — Powered by an RP2040

Large Tree Tech (BTT) has launched an aggressively-styled management board for 3D printers, powered by the Raspberry Pi RP2040 microcontroller — and that includes a classy heatsink with a design extra generally discovered on gamer-centric PC motherboards.

Developed particularly for the Voron V0 3D-printer venture although appropriate with different units, and delivered to our consideration by Electronics Weekly, the BTT SKR Pico seems for all of the world like a bit of gaming PC tools — full with black PCB and a chunky heatsink with purple and white highlights.

Designed to be as compact as doable, at a footprint of 85×56mm (round 3.39×2.2″), the guts of the SKR Pico is the Raspberry Pi RP2040 microcontroller — additionally discovered within the Raspberry Pi Pico growth board from which BTT has gently borrowed the gadget’s title. Just lately launched for direct buy for as little as $0.70 per unit, the chip features a dual-core Arm Cortex-M0+ processor with 264kB of static RAM (SRAM) and a intelligent programmable enter/output (PIO) block with as much as eight state machines.

Mounted in a four-layer board, the RP2040 controls 4 TMC2209 stepper motor drivers — positioned beneath the heatsink for improved cooling, although BTT advises that an energetic cooling fan ought to be added if greater than 0.8A is drawn by means of the drivers — and is in flip below the management of the Klipper 3D printer management software program working a Raspberry Pi single-board laptop, not equipped, with official help for the full-size Raspberry Pi vary or significantly extra compact Raspberry Pi Zero household.

Apparently, BTT has opted — once more, following within the footsteps of gaming {hardware} producers — to launch two totally different variations of the board. The usual Pico version contains the customized heatsink, however is in any other case a naked board; the Pico Armored, in the meantime, provides a metallic cowl over the majority of the board – although whether or not this offers any profit past aesthetics shouldn’t be instantly apparent.

The boards have been listed on the Biqu web site at $35.68 for the Pico and $39.98 for the Pico Armored, however solely the previous mannequin is obtainable to pre-order forward of anticipated inventory arrival on February twentieth. Each costs embrace, the corporate claims, a $20 pre-order low cost off the eventual retail worth.
