Rodent¶
Product Profile¶
The BIGTREETECH Rodent V1.0 is our very first control board designed specifically in collaboration with RatRig for CNC machines. It supports USB and RS-485 communication, greatly simplifying the wiring process and providing smooth operation.
Feature Highlights¶
- MCU: ESP32-D0WD-V3.
- Wi-Fi Capability: Supports 802.11 b/g/n, 802.11 n (2.4 GHz) with maximum speeds of 150 Mbps.
- Integrated Motor Drivers: Onboard four TMC2160 drivers, capable of handling high voltage and current, making them ideal for more powerful motors.
- Power Input Range: DC24V to DC56V at 10A.
- V-MOS Power Input: Accepts DC12V to DC36V with three externally controllable voltage output ports, supporting up to 5A; output voltage depends on the V-MOS input.
- 5 Endstop Switch Interfaces: Support voltage selection of 5V, 12V, and VIN, featuring optocoupler isolation to improve motherboard stability and reduce interference.
- VProbe Control Switch Interface: Support voltage selection of 5V, 12V, and VIN, featuring optocoupler isolation to improve motherboard stability and reduce interference.
- Spindle control interface.
- One PWM output interface (3-10V).
- One TF card interface.
- Firmware Management: Features TYPE-C automatic firmware burning and onboard CH340 for easy updates without external tools. Includes BOOT and RESET buttons for entering DFU mode via USB.
- RS485 Support: Includes a built-in 130R terminal resistor for RS485 communications.
- Expansion Interfaces: Reserved connections for an OLED display (I2C) and Wi-Fi antenna, and supports 3-channel RGB LEDs for customization.
