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/ADA5302:1.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 A wild Kee Boar appears! It’s a shiny **KB2040**! An Arduino Pro Micro-shaped board for Keebs with RP2040. (#keeblife 4 evah) A lot of folks like using Adafruit parts for their Keeb builds – but with the ItsyBitsy not being pin-compatible with the Pro Micro pinout, it really wasn't very easy without some sort of adapter plate. Now we’re seeing lots of people use CircuitPython for keebs, which is awesome! So why not try Adafruit's hands at spinning up a pro-micro-compatible RP2040 board? The RP2040 is plenty powerful, low-cost, and makes for an excellent keeb driver chip. Adafruit mixed together what Adafruit liked most about the SparkFun Pro Micro RP2040 (**Qwiic / STEMMA QT I2C port on the end**, so good!) and Elite-C (**castellated pads & pins for D+ and D-**) and Adafruit's existing RP2040 boards (**boot button can be used for user, 8MB QSPI flash, onboard NeoPixel, jumper for skipping the diode/fuse for high power RGB LEDs or USB hosting**). Adafruit even got it to all fit on a 2-layer PCB with 7/7 routing – just needed to make the smallest caps and resistors 0402. With 20 GPIO available (18 on castellated pins, 2 on STEMMA QT port) you can easily make up to 100-keys matrices, or common 65% 5x15 layouts. [Use a plug-and-play QT cable to connect to the last two pins](https://core-electronics.com.au/jst-sh-4-pin-to-premium-male-headers-cable-qwiic-compatible-150mm-long.html) without having to do any desoldering/rework. ### Board features: - [Same size and form-factor as a Pro Micro breakout](https://www.sparkfun.com/products/12640) and nearly-identical pinout (this board has fewer analog pins, for example) - Measures 1.3" x 0.7" without headers soldered in - RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3V logic and power. 264 KB RAM, No EEPROM. 12 MHz crystal for perfect timing. - **8 MB SPI FLASH** chip for storing files and CircuitPython/MicroPython code storage. - **20 x GPIO pins with following capabilities:** - 18 GPIO on castellated/pin breakout pads. 2 GPIO on QT port that can be easily accessed for 5x15 keyboard layouts. - Four 12 bit ADCs - Two I2C, Two SPI and two UART peripherals, Adafruit label one of for the 'main' interface in standard Pro Micro locations - 16 x PWM outputs - for servos, LEDs, etc - The 10 digital non-ADC GPIO are consecutive for maximum PIO compatibility - **RGB NeoPixel** for colorful status indiction - Classic **green power LED** - Both Reset button and Bootloader select button for quick restarts. Bootloader button is also available as a generic GPIO input button. - [STEMMA QT connector](https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) on the end is compatible with the [SparkFun Qwiic](https://www.sparkfun.com/qwiic) I2C connector, and can be used to plug and play I2C devices, or just as 2 extra GPIO pins. - 3.3V regulator with 500mA peak current output - **RAW** output, for powering NeoPixels or other 5V devices. Jumper on bottom lets you skip over the 500mA fuse, for up to 2A from USB ports. - **USB Type C connector** lets you access built-in ROM USB bootloader and serial port debugging - **Extra D- and D+ breakouts** for alternative USB connection options. ### RP2040 Chip features: - Dual ARM Cortex-M0+ @ 133MHz - 264kB on-chip SRAM in six independent banks - Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus - DMA controller - Fully-connected AHB crossbar - Interpolator and integer divider peripherals - On-chip programmable LDO to generate core voltage - 2 on-chip PLLs to generate USB and core clocks - 30 GPIO pins, 4 of which can be used as analog inputs - Peripherals - 2 UARTs - 2 SPI controllers - 2 I2C controllers - 16 PWM channels - USB 1.1 controller and PHY, with host and device support - 8 PIO state machines Product Dimensions: 35.0mm x 17.8mm x 4.9mm / 1.4" x 0.7" x 0.2" Product Weight: 2.8g / 0.1oz ### Resources [RP2040 Datasheet](https://core-electronics.com.au/attachments/localcontent/rp2040_datasheet_51483bc02aa.pdf) ![RoHS 2 2011 65 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2011_65_EU_7356c5574c.svg) ![RoHS 2 2015 863 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2015_863_EU_86773f57f9.svg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_12063.jpg)
