We all know Raspberry Pi is a mini-computer running on Linux operating system; while Arduino is a microcontroller running on simple I/Os. Both of them focuses on very different areas. Compared with Arduino, the Pi gets much better computing performance. ## Pricing - **Price:** $33.75 (inc GST) — $30.68 AUD, exc GST - **Quantity discounts:** 6+ $29.15 (exc GST) · 12+ $27.92 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 24 and Aug 27. ## Restrictions Restrictions apply to this equipment as it uses button/coin cell batteries: - The equipment is intended to be used in trades, professions or industries - The equipment is not intended for sale to the general public - The equipment is not intended to be used where children are present - You are aware that this equipment may not meet child safety testing requirements as it is not intended to be used by consumers or general public, but rather, is intended to be used in trades, professions or industries in conjunction with the limitations and restrictions listed above - You are aware that these restrictions are due to a change in [A](https://www.accc.gov.au/media-release/businesses-on-notice-as-mandatory-button-battery-laws-commence)[ustralian legislation in 2022](https://www.accc.gov.au/media-release/businesses-on-notice-as-mandatory-button-battery-laws-commence) for button/coin cell batteries ![Button Battery Warning](https://core-electronics.com.au/attachments/uploads/iec-button-battery.png) A declaration of use will need to be submitted during checkout. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0327:1` (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/DFR0327:1.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 **Introduction** What's the difference between Pi and Arduino? We all know Raspberry Pi is a mini-computer running on Linux operating system; while Arduino is a microcontroller running on simple I/Os. Both of them focuses on very different areas. Compared with Arduino, the Pi gets much better computing performance. So What happens when a Pi meets an Arduino? A simple example would be, when building a mobile robot, we use the Raspberry Pi to extend its vision and get a nice tiny monitor. Meanwhile, Arduino handle nicely with the motor driving part and delivers fast responses like obstacle avoidance. Because, without the OS, the response time of rapid changes on the Arduino is much shorter. Also the high performance Pi can deals much easily with wireless communications, imaging and running complex algorithm. Therefore, with the Arduino and Pi together, you get a powerful "brain" and "cerebellum" for your project, at one time.**Specification** - Onboard Microcontroller: ATmega32u4 - Arduino Leonardo Chip - Arduino Compatible pin mapping - Compatible with All arduino standard shield and sensors - System Voltage: 5v - Arduino Digital I/O: 23 - Arduino Analog I/O: 12 - Raspberry Pi B+ GPIO: 16 - Raspberry Pi B+ I2C: 1 - Raspberry Pi B+ ID\_I2C: 1 - Raspberry Pi B+ SPI: 1 - Raspberry Pi B+ TTL UART: 1 - Dimension: 88mm x 56mm x 26mm **OPTIONAL PARTS** - Relay Module V3.1 for IOT AC control - Analog pH Meter Kit for monitoring Water quality of your pool - SHT1x Humidity and Temperature Sensor - Motion Sensor for security and human detection - A nice and low cost LCD12864 display - 2A Motor Shield for robot building - Dual Bipolar Stepper Motor Shield - GSM/GPRS and GPS Shield **Documents** - Wiki Doc - [Schematic](https://core-electronics.com.au/attachments/localcontent/DFR0311_v1_Schematic_1435821fce8.pdf) - [Assembly Drawing](https://core-electronics.com.au/attachments/localcontent/DFR0311_v1_Schematic_1435821fce8.pdf) **Parts List**- Arduino Expansion Shield for Raspberry Pi B+ x1 - 20cm micro USB cable x1 - CR1220 button cell x1 ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/d/f/dfr0327-01.jpg)
