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/CE08399:1.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 Giant Butterfly allows four HATs or pHATs (or a mix) to be attached to a single [Raspberry Pi](https://core-electronics.com.au/raspberry-pi/boards/model-b.html) 40-way connector. All pins are connected and the ID\_SD and ID\_SC (HAT EEPROM) have cuttable solder jumpers. For HATs and pHATs with an EEPROM (required by the HAT specification), you will need to cut the ID solder jumpers (with a [sharp knife](https://core-electronics.com.au/hobby-knife.html)) to prevent conflicts. The EEPROM on the primary HAT (over the Pi) is always connected to the Pi. If at a later date you require the ID pins to be reconnected this can be done by bridging the jumper with solder. **Note**: The Giant Butterfly uses a 4-layer PCB to achieve its small footprint. Due to the traces crossing over each other we do not recommend using it where high-frequency signals/switching is required. **Raspberry Pi, headers and HATs not included.** **Before Using** When using multiple HATs you MUST check for conflicts - for example, enable/select pins when using SPI, I2C addresses and GPIO pin conflicts and modes, 8086 advise checking on [pinout.xyz](https://pinout.xyz/) and/or with the HAT manufacturer for used pins/modes in use. **Assembly / Soldering** The Giant Butterfly board would normally be used with 3x [male](https://core-electronics.com.au/raspberry-pi-gpio-male-header-2x20.html) + 1x [tall stacking headers](https://core-electronics.com.au/stacking-header-for-raspberry-pi-b-2x20-extra-tall-header.html) (not included). The tall stacking header is for the Raspberry Pi and the primary HAT, and the male headers is for the other HAT positions. - The top side of the board has the "Giant Butterfly" text and the underside has the ID solder jumpers. - **See the important notes below for the primary HAT position**. Push the female header with long pins through from the bottom and solder into the holes closest to the HAT position marked "RPi". - Next the 3 male headers can be soldered into the other 3 positions. **Important Notes** - When soldering the long female header onto the Giant Butterfly please be aware of the clearance with the USB/Ethernet connectors on the Raspberry Pi. [Use a tall header with shrouds like this one](https://core-electronics.com.au/stacking-header-for-raspberry-pi-b-2x20-extra-tall-header.html). - Either way, 8086 strongly recommend applying a couple of layers of [electrical insulation tape](https://core-electronics.com.au/electrical-tape) onto the top of the connector (USB\[Pi4\]/Ethernet) under the Giant Butterfly board to prevent shorts. - Pin 1 of each HAT position is marked with a white line next to the square pad. ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_13058.jpg)
