Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/WS-23730:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Based on the ESP32-WROOM-32 module, supporting wireless communication options such as WIFI, Bluetooth, and ESP-NOW. It features motor control interfaces capable of handling up to two DC motors with encoders or four DC motors without encoders, arranged in two groups. Additionally, it can manage up to 253 ST3215 serial bus servos and provide servo feedback. An onboard 9-axis IMU supplies real-time attitude and heading information. With power input acceptance ranging from 7 to 13 volts, it is designed to connect directly to 2S or 3S lithium battery modules. The system incorporates an automatic download circuit for straightforward programme uploads and includes features for monitoring voltage and current input. Equipped with a TF card slot, a Laser Lidar interface, and an integrated UART to USB function, its performance capabilities are enhanced. The I2C interface allows for connecting peripherals such as OLED displays and other I2C devices. Moreover, the system comes with a multifunctional extended header suitable for additional functions like controlling servos or relays, alongside a 40-pin GPIO header to connect and power host computers such as the Raspberry Pi or Jetson Nano, facilitating communication via serial port or I2C. ## Specifications - **Control module**: ESP32-WROOM-32 - **Power supply**: DC 7~13V - **Power interface**: XH2.54 - **Antenna connecto**r: IPEX1 - **Download interface**: Type-C - **Dimensions**: 65 × 65mm - **Mounting hole spacing**: 49 × 58mm - **Mounting hole diameter**: 3mm ## What's On Board ## ![](https://core-electronics.com.au/attachments/localcontent/General-Driver-for-Robots-details-intro_19433c3c400.jpg) 1. **ESP32-WROOM-32 controller module** Can be developed using Arduino IDE 2. **IPEX1 WIFI connector** For connecting WIFI antenna to increase the wireless communication distance 3. **LIDAR interface** Integrated radar adapter function 4. **I2C peripheral expansion interface** For connecting with OLED screen or other I2C sensors 5. **Reset Button** Press and release to reboot the ESP32 6. **Download button** The ESP32 will enter the download mode after powering on 7. **DC-DC 5V voltage regulator circuit** Power supply for host computers such as Raspberry Pi or Jetson nano 8. **Type-C port (LADAR)** LIDAR data transmission 9. **Type-C port (USB)** ESP32 communication interface, for uploading programs to ESP32 10. **XH2.54 power port** Support DC 7~13V input, can directly power the serial bus servos and motors 11. **INA219** voltage/current monitoring chip 12. **Power ON/OFF** External power supply ON/OFF 13. **ST3215 serial bus servo interface** For connecting with ST3215 serial bus servo 14. **Motor interface PH2.0 6P** Group B interface for motor with encoder 15. **Motor interface PH2.0 6P** Group A interface for motor with encoder 16. **Motor interface PH2.0 2P** Group A interface for motor without encoder 17. **Motor interface PH2.0 2P** Group B interface for motor without encoder 18. **AK09918C** 3-axis electronic compass 19. **QMI8658C** 6-axis motion sensor 20. **TB6612FNG** Motor Control Chip 21. **Serial bus servo control circuit** for controlling multiple ST3215 serial bus servos and obtaining servos feedback 22. **TF card slot** Can be used to store logs or WIFI configurations 23. **40PIN GPIO header** For connecting with Raspberry Pi or other host boards 24. **40PIN extended header** Easy to use the GPIO pins of Raspberry Pi or other host boards 25. **CP-2102** UART to USB, for radar data transmission 26. **CP-2102** UART to USB, for ESP32 communication 27. **Automatic download circuit** For Uploading programs to the ESP32 without pressing the EN and BOOT buttons ## Dimensions ## ![](https://core-electronics.com.au/attachments/localcontent/General-Driver-for-Robots-details-size_20020d05805.jpg) ## Resources - Wiki ## Shipping List - 1 x General Driver for Robots - 1 x Bluetooth antenna - 1 x Screws pack ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/C/E/CE09537-1.jpg)
