Xilinx Adaptive Computing Challenge 2021 at

The 2021 Adaptive Computing Challenge at will reward top Xilinx development projects up to $10,000 (prizes are all Visa gift cards).   You can apply for free hardware to compete in the contest until October 15, 2021.  Final submissions are due February 28, 2022.  The Xilinx University Program is sponsoring an additional $2500 prize for college students.

There are three main categories in the contest: Edge Computing, Data Center AI and Big Data Analytics.  The edge computing requires a solution running on the Xilinx Kria KV260 Vision AI Starter Kit.  Data center AI must use the Xilinx VCK5000 development card.  Big data analytics requires the Xilinx Big Data Analytics card (not much information on this board).

The Kria KV260 Vision AI Starter Kit is listed at $199 but currently out of stock at most distributors.  It is meant for vision application development for Edge computing.  It has multiple camera interfaces including support for the Raspberry Pi camera module.  Multiple cameras are supported by using additional interfaces such as IAS or USB.  A power supply is also required.  One is also included in the  basic accessory pack which also includes a 13MP camera module, available from Xilinx for $59.

Arduino Sensor Kit

Arduino and Seeed have released the Arduino Sensor Kit for $23 (USD).  The kit includes 10 modules and sensors including light, sound, air pressure, temperature, an accelerometer, buzzer, button, and a small OLED screen.  The Arduino sensor kit base is an Arduino Shield (daughterboard) so you will need an Arduino UNO or compatible board to use it.  If you buy both from Arduino you can get them bundled for a discounted price ($38.70).  The Arduino Sensor Kit can be purchased directly from Arduino or Seeed and Arduino has developed a step-by-step tutorial to go with it and the Arduino UNO. 

Seed has a very similar all-in-one board, the Seeed Grove Beginner Kit for Arduino ($19.90), which includes an Arduino compatible base board.

Atmel-ICE and Development Board Sale at

The Atmel-ICE Full Kit is half off with coupon code TP1747 until February 28, 2018.  A few other development boards are discounted as well.  See details at

I have used the Atmel-ICE with a few different AVR microcontrollers along with the Atmel Studio 7.  It works well but I have had a few small issues with JTAG debugging from Atmel Studio, usually I just restart the debug session and things work.  Definitely the best tool I have found for AVR JTAG debugging. For more information see the the Atmel-ICE product page.  The link to the online user's guide on that page is currently broken, I will add it to the comments if I can find a link.  Here is the Atmel-ICE User Guide at DigiKey.  The Youtube video Atmel Edge With Paul Rako: Debug 102 shows and unboxing and goes over the basics of the kit.  The video is embedded below (no pun intended).
