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/DEV-15110:1.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 The SparkFun ESP32 Thing Plus DMX to LED Shield is the perfect way to send and receive DMX data. Whether it's coming in via the onboard XLR-3 jack or ArtNet, or outputting over the XLR-3 Jack/ArtNet, this shield has you covered! It's the perfect way to get started developing your own custom DMX fixtures, or even adding ArtNet capabilities to a current fixture. It also holds up to the DMX standard which requires electrical isolation between the controller and communication side to avoid ground loops. The DMX to LED Shield can be powered either through the screw terminals or the USB connection from your microcontroller that's plugged into the shield. The screw terminal is a 2-pin 3.5 mm screw terminal capable of accepting 26-16 AWG wire with a strip length of ~5-6mm. Please note that you should always power the shield with 5V to provide proper power for RS485. The outputs are broken out to poke home connectors ordered to match up with APA102 LED strips and LuMini devices. The DMX to LED shield is designed to work with the SparkFun Thing Plus - ESP32 WROOM or any board with a Feather footprint, so Feathers and Feather-Wings will fit it. Since many Feather boards are 3.3V logic, there is a logic level converter between the microcontroller and LED data pins to bring the poke home connectors up to 5V logic.
