NerdRalph’s story on upgrading GPU capabilities without using all new hardware.
My old card had two 6-pin connectors, which I had plugged a 1-2 18AWG splitter cable into. That was connected to a 16AWG PCIe power cable, which is good for about 200W at a drop of under 0.1V. My new card with the single 8-pin connector wouldn’t power up with just a 6-pin plug installed. Using my multi-meter to test for continuity between the pins, I realized that it’s not just a row of 12V pins and a row of ground pins.
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.
