Something that Klipper will allow us in any case is to be able to have a lower-level control of our machine. In this way your printer will be able to operate with greater speed and precision, always depending on the hardware that we have at our disposal. Klipper is an open-source firmware for our 3D printers that mainly use the power of a Raspberry Pi to control all electronics, although it can be mounted on many more devices.

SPI BUS expansion port for SPI modules such as MAX31865.

CAN BUS via 6P6C RJ11 connector for future expansion modules.

The PROBE port was added extra protection with an optocoupler so as not to need to use a BAT85 diode

BLTouch support and the like with a connector intended for them and usable by other ABL systems.

It allows reusing these pins for other tasks with a pin that bypasses these protections

Protection against short circuit in thermistors, another great improvement applied to the fans.

PT100 interface (requires INA8 amplifier 26AIDR welded to plate in socket).

Connector for WiFi interface ( ESP8266).

Improvements in the bootloader, supporting the update by USB (recommended) and DFU (advanced users).

High performance MOSFETs, improve heating speed and efficiency.

Compatibility with almost any screen, although we recommend using SKR dual displays.

USB-C connector that allows serial emulation to print using USB.

Protection against short circuit on fans, something very important since it is one of the most common problems.Up to 6 controllable fans and 2 without control with the possibility of voltage selection (Vin, 12V and 5V).Integrated DCDC to provide 12V(4A), 5V(8A) and 3.3V(1A) power supply.Interfaces for Raspberry Pi (USB and UART by GPIO).Support for Klipper and Marlin firmwares.ARM Cortex-M4 STM32F446ZET6 32-bit microcontroller at 180MHz.We proceed to list here some of the most important characteristics of the BTT Octopus electronic board:
