The V4.9 PLUS and later Versions can adapt a 150 * 90 * 40mm box and use screw terminals
V4.9 PB Compared to Previous
1. Fits in a 150 * 90 * 40mm box (needs to be purchased separately)
2. Changed output connector to screw terminal method
3. Changed to external antenna for better speed and stability
4. Separate main power supply and stepper motor power supply inputs
5. Uses plugs to change output for drivers or motors
6. Supports onboard TMC2130 and TMC5160 drivers, as well as external TMC5160 drivers (only for 2025 V49PB)
7. CP2102 chips procured from Silicon Labs' official authorized suppliers
8. Genuine ESP32 chips procured from Espressif's official suppliers for greater stability and reliability
V4.96 Pro Compared to V4.9 PB
1. The board features a 4-layer PCB design with impedance-controlled manufacturing, upgraded component suppliers, and solid capacitors with voltage ratings increased from 35V to 50V.
2. The layout has been optimized with a dedicated power plane and improved SPI signal routing, The layout was inspected by engineers from three separate companies.
3. The SW_VCC selector supports standard limit switches, medium-precision 5V types, or high-precision industrial-grade 12V/24V limit switches.
4. All limit switch inputs include diode protection and status LEDs.
5. Signal output indicators have been added for all stepper motors with integrated LEDs.
6. The SPI external port now uses CS.X instead of GPIO5 for more intuitive wiring.
