Isik’s Tech Hedgehog CAN/USB Klipper I/O Expander

Description

Hedgehog is a Klipper expansion PCB with 31 I/O pins,designed for cases when you just need a simple board to connect a few things to your printer, like pins for buttons, thermistors, I2C/SPI devices, etc.

Hedgehog, unlike generic MCU breakout boards, is designed with ease-of-use with Klipper in mind:

• Are you wiring a bunch of buttons and don’t want to join many wires to one pin?Hedgehog has a pair of 3.3V and GND foreachpin.
• Do you want to use CAN bus, and don’t want to wire a separate CAN module?Hedgehog has a CAN transceiver built-in, and supports both USB and CAN.
• Do you only have 24V available where you’re planning to place the board?No problem, Hedgehog supports 24VIN.
• Do you want to connect a few thermistors, and don’t want to solder pullup resistors?Hedgehog as pullups and protection for 3 thermistors built-in.
• Are you designing a custom board for your application and need a simple MCU breakout board to slot into your design?Hedgehog uses standard 2.54mm (0.1″) pitch pin headers for its I/O, so you can easily slot it into standard female headers on your design.

Hedgehog uses a STM32G0B1 MCU, supporting Klipper, STM32Duino and many other firmwares.

Hedgehog is assembled in America.
