# Piantor > The Piantor Keyboard is a beginner-friendly, easy-to-solder, 42-key or 36-key, diodeless, low profile aggressive column staggered, hotswappable and non-hotswappable, programmable ergonomic mechanical split keyboard powered by Raspberry Pi Pico or other compatible RP2040 boards. It is based on the Cantor Keyboard. ## Overview # Piantor Keyboard ![Piantor Keyboard](https://raw.githubusercontent.com/beekeeb/piantor/HEAD/docs/banner.jpg) [![License: GPL v3](https://img.shields.io/badge/License-GPLv3-blue.svg)](https://www.gnu.org/licenses/gpl-3.0) The Piantor Keyboard is a 42-key or 36-key wired, diodeless, non-flippable, low profile choc v1 (hybrid hotswap and non-hotswap/soldered-in), aggressive column staggered, programmable ergonomic mechnical split keyboard powered by Rasyberry Pi Pico or other compatible RP2040 boards. It is based on the [Cantor Keyboard](https://github.com/diepala/cantor). The name "Piantor" is the portmanteau of "Pico" and "Cantor". The development of this project is sponsored by [PCBWay](https://pcbway.com/g/beekeeb) (affiliate link). ## Quick Links * [Build guide](https://docs.beekeeb.com/piantor-keyboard#build-guide) * [Precompiled firmware](https://docs.beekeeb.com/piantor-keyboard#precompiled-firmware) * [beekeeb showcase](https://showcase.beekeeb.com/piantor-keyboard/) ## Features * RP2040 MCU - A low-cost, easy-to-source, powerful microcontroller with dual Arm Cortex-M0+ @ 133MHz, 264kB on-chip SRAM and 2MB (up to 16MB, depending on the breakout board) off-chip external flash memory. You can enable a lot of features and layers. Never worry about the firmware size limit. * Cantor layout - Ergonomic strong column staggering for short pinkies. * Non-flippable PCBs - Fewer ways to make mistakes when you install the controller breakout boards. Great for first time keyboard builders. * Diodeless - A more robust build with fewer things to solder or break. * Hybrid hotswap and soldered-in low profile choc switches - Experiment with different key switches with the hotswap sockets, or solder the key switches for a more stable build. * Breakable pinky column - Easily convert the PCB from a 42-key to 36-key layout. You can snap off the pinky column without specialized tools. ## Bill of Materials (BOM) Quantity | Item | Notes --- | --- | --- 1 | Piantor PCB (Left) 1 | Piantor PCB (Right) 2 | RP2040 breakout boards (such as Raspberry Pi Pico or WeAct RP2040) 42 (or 36) | Kailh choc v1 PG1350 switches 42 (or 36) | "choc spacing" choc v1 keycaps 2 | TRRS jack (PJ-320A) 1 | 3.5mm TRRS cable | TRS cable cannot be used 42 (or 36) | CPG135001S30 hotswap sockets for choc v1 PG1350 | Optional, you can solder the switches directly if you do not use hotswap sockets 4 | Pin headers (20p) or sockets | Only required for boards without castellated holes 2 | 10kΩ 1206 (3216M) SMD resistor | Only required if you do not want to use SPLIT_USB DETECT, and for boards without a built in VBUS_SENSE circuit 2 | 5.6kΩ 1206 (3216M) SMD resistor | Only required if you do not want to use SPLIT_USB DETECT, and for boards without a built in VBUS_SENSE circuit * Note: Raspberry Pi Pico comes with castellated holes and a built in VBUS_SENSE circuit ## Ordering Parts [DIY kits](https://shop.beekeeb.com/product/piantor-keyboard-kit/) and [prebuilt keyboards](https://shop.beekeeb.com/product/pre-soldered-piantor-split-keyboard/) are available at https://beekeeb.shop If you prefer getting the parts by yourself, you can order the [Left Side PCB](https://www.pcbway.com/project/shareproject/Piantor_Keyboard_Left_side_24a2937f.html) and the [Right Side PCB](https://www.pcbway.com/project/shareproject/Piantor_Keyboard_Right_side_7c5b31eb.html). A single side should cost around $31 for 5 pcs excluding shipping. For both sides, it should be around $62 in total for 5 sets. ## Firmware Status * [QMK](https://github.com/qmk/qmk_firmware) - supported * [Vial](https://github.com/beekeeb/vial-qmk-piantor) (based on QMK) - supported * KMK (Python/CircuitPython) - pull request at https://github.com/KMKfw/kmk_firmware/pull/723 * [An example of KMK with miryoku](https://github.com/hansamann/piantor_miryoku_mac) by [hansamann](https://github.com/hansamann) * Remap - support planned (No ETA) * PRK (Ruby) - support planned (No ETA) * keyberon (Rust) - support planned (No ETA) * ZMK - waiting for [wired split support](https://github.com/zmkfirmware/zmk/issues/1110) Precompiled firmware can be found at https://docs.beekeeb.com/piantor-keyboard. ## Cases * [Piantor Gasket Mount Case by chewiedies](https://www.printables.com/model/536044-piantor-gasket-mount-case) * [Piantor 36-key case with Tenting & Magnets! by Daave](https://www.printables.com/model/381730-piantor-36-key-case-with-tenting-magnets) * [Travel case for Piantor keyboards by Rilton](https://www.printables.com/model/558902-travel-case-for-piantor-keyboards) ### Piantor Case with a Switch Plate (3D Printable) ![Piantor Keyboard Case](https://raw.githubusercontent.com/beekeeb/piantor/HEAD/case/top.jpg) ![Piantor Keyboard Case](https://raw.githubusercontent.com/beekeeb/piantor/HEAD/case/side.jpg) The 3D printable case can be founded in the [case folder](./case). The switch plate is optional for the non-hotswap version. GB823 M2 stainless steel screws with small pan heads are recommended. * Screw Length * No switch plates: 4mm * With Switch plates: 6mm * With Switch plates and [Donut0804](https://shop.beekeeb.com/product/donut-silicone-rubber-feet-and-pads-o-rings-washers-like/)/o-rings: 7mm Do not over-tighten the screws. ### Cantor Tray Case The [Cantor Tray Case](https://www.thingiverse.com/thing:5382705) by chewiedies can be used. There is not a switch plate so it is not recommended for the hotswap version. ## Boards Preview
