I wanted to get an off-the-shelf Spartan 7 FPGA board, essentially to bring up the FPGA side of an eventual move to my own development board. When I saw the Digilent Arty S7 announced last year, I kept an eye on it knowing it would be a contender for my upgrade path to the 7-series chips. The Arty S7 I ended up purchasing is the S7-50 variant, sporting the XC7S50 Spartan 7 FPGA with significantly more resources than my previous Spartan 6 board. It also had 256MB DDR3 RAM, but lacked HDMI connectivity. Thankfully, the HDMI/DVI-D output issue has been solved.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
