Designed for makers, educators, developers; Bluno has helped tons of ideas become prototypes. Today, please allow me to introduce a new member in this flourishing BLE family: BLUNO MEGA. ## Pricing - **Price:** $47.10 (inc GST) — $42.82 AUD, exc GST - **Quantity discounts:** 6+ $40.67 (exc GST) · 12+ $38.96 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Sep 01 and Sep 07. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0323:1` (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/DFR0323:1.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 Last year we introduced you BLUNO, our first Arduino-compatible hardware solution that integrates Bluetooth 4.0 (BLE). Designed for makers, educators, developers; Bluno has helped tons of ideas become prototypes. Today, please allow me to introduce a new member in this flourishing BLE family: BLUNO MEGA. Bluno Mega2560 inherits the numerous ports and the abundant resources of Mega series, and adds Bluetooth 4.0 wireless communication function. It has 54 digital I/O (input/output) ports (15 of which can be used as PWM output), 16 analog input and 4 UART (hardware serial ports), and uses 16 MHz imported crystal oscillators. So, if you are feeling a lack of ports or desire more RAM, flash or EEPROM memories, here is the answer. With it's bootloader it can directly download programs via USB without any other external flashing devices. Mega 2560 has twice as big memory space as 1280 and 256k flash memory. Bluno Mega2560 has two options for the power supply system, including USB power supply or external power supply. The power supply will be automatically switched. External power supply can use an adapter or a battery and the range of voltage limit of the control board is from 5V to 23V. BLUNO MEGA integrates a TI CC2540 BT 4.0 chip. It allows wireless programming via BLE with two devices, supports Bluetooth HID, AT command to config BLE and you can upgrade BLE firmware easily. What's more, fully compatible with all Arduino Mega pins which any project made with Mega can directly go "Blue"! ### Specification - Microcontroller:ATmega2560 - Clock frequency: 16MHZ - Transmission distance: 70m in open space - Support bluetooth remote update the Arduino program - Support bluetooth HID - Support iBeacons - Support by the AT command to debug the BLE - Support transparent transmission serial port - Support the master-slave machine switch - Support usb update BLE chip program - Working voltage:+5V - External input voltage (recommended):7 ~ 12V DC - External input voltage (range):6 ~ 20V DC - Digital I/O outputs: 54 (14 PWM outputs) - Analog inputs: 16 - I/O current: 40mA - Flash capacity: 256KB (4k for bootloader) - Static storage capacity of SRAM: 8KB - Memory capacity of EEPROM: 4KB - Size: 108 x 54mm ### Documents - Wiki Doc - [Datasheet](https://core-electronics.com.au/attachments/localcontent/Atmega1280-2560datasheet_166279403aa.pdf) - [Schematics](https://core-electronics.com.au/attachments/uploads/DFR0323.pdf) ### **Parts List** - BLUNO MEGA 2560 x1 ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/d/f/dfr0323-01.jpg)
