> **Source:** Core Electronics is an Australian maker-electronics retailer and manufacturer based in Newcastle, NSW, run by a team of makers and educators. We design and manufacture our own product lines (PiicoDev, CE originals) and are official retailers for iconic maker and industrial brands including Raspberry Pi, Arduino, Adafruit, SparkFun and DFRobot. Orders ship Australia-wide from our Newcastle warehouse. Prices are in AUD and include GST. Pricing, stock and dispatch on this page are generated from the store's live catalog.

We needed a cost effective solution for in house debugging, the ability for customization, and something we can include on test fixtures. ## Pricing - **Price:** $26.90 (inc GST) — $24.45 AUD, exc GST - **Quantity discounts:** 10+ $23.47 (exc GST) · 25+ $22.75 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 8 today; more stock is typically available with a 4–24 day lead time. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE08171:1` (comma-separated SKU:qty pairs) and share the link. 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/CE08171:1.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 Jeff Probe is an open source JTAG probe based entirely off the popular black magic probe. We needed a cost effective solution for in house debugging, the ability for customization, and something we can include on test fixtures. We leveraged our volume and made Jeff Probe in hopes to give back to the community and give students an opportunity to get an affordable JTAG solution. Visit the FLIRC [github](https://github.com/flirc/blackmagic) project page to check out the source code, contribute, or branch. We are also tracking the latest stable branch of the official black magic probe hardware. **FAQs from FLIRC** **1. Is the black magic probe better?** The BMP is all around better. I wont lie. You get what you pay for. It's going to be supported by the inventor himself. It's built with a Cortex m3, it's faster, and is guaranteed to run the bleeding edge software. If you can afford their hardware, support them. **2. Is there anything better with this over the black magic probe?** If you are debugging a chip with single wire JTAG, there is a supported hardware command to enable UART over the existing JTAG connector. That means, the single JTAG cable can be used for both debug, and the second UART connection. No need for two cables, simplifying connections, and using the JTAG cable, which has better reliability. **3. Do you have the schematics Available?** Yes, they will be posted to the github directory shortly. **4. What are the supported target voltages?** 1.8V-5V **5. What does it ship with?** The JTAG connector, the UART connector, the Black Magic Probe. It does not ship with a USB micro cable. **6. What is the firmware version?** We branched our code off public release v1.6 of the bmp. They are quite ahead of this now, but we wanted to use a stable branch. We will rebase on another branch soon, and will merge our master branch only when they release their new stable branch. **7. The LEDS are too bright.** Yeah, we know. Don't stare at them. **8. Do you plan on making a case for this?** Nah. ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_2974.jpg)
