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-21593:1.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 ## Details ESP32 Servo Driver expansion board, Built-in WiFi and Bluetooth ESP32 Servo Driver expansion board dedicated driver board designed for serial bus servos ![](https://core-electronics.com.au/attachments/localcontent/Servo-Driver-with-ESP32-details-1_948300c8251.jpg) Allows controlling up to 253 servos via the ESP32 serial port, with open source bottom layer and web application, as well as open source hexapod walker and humanoid robot structures, ideal to be used as the main controller while building robotics projects. Features at a glance - Allows controlling up to 253 SC, ST series serial bus servos at the same time (adequate power supply required) - Wide range voltage input 6-12V (the input voltage and the servo voltage must be matched) - Built-in WiFi and Bluetooth, as well as ESP-NOW support, for remote control and servo debugging - Automatic download circuit for easy uploading programs - Open source web application and various robot structures - Compact size and space saving, suitable for integration into sorts of space-limited projects Specifications | Supply voltage | DC 6-12V | |---|---| | Power supply connector | 5.5 × 2.1mm DC | | Download interface | Type-C | | Controller | ESP32 | | Control interface | UART | | Dimensions | 30 × 65mm | | Mounting hole size | 2.75mm | | Mounting hole spacing | 23 × 58mm | Application examples - Servos will provide various feedback like position, speed, torque lock, operating mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control - Ideal choice for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos ![](https://core-electronics.com.au/attachments/localcontent/Servo-Driver-with-ESP32-details-3_55028d73a12.jpg)\* images here are for reference ONLY UART serial bus control Allows controlling up to 253 SC, ST series serial bus servos at the same time ![](https://core-electronics.com.au/attachments/localcontent/Servo-Driver-with-ESP32-details-5_12312cde3cb.jpg) **Note:** though one channel UART is able to control up to 253 bus servos, due to the high power of the servos, it is necessary to consider whether the power supply solution is enough when using too many servos.
