The official Raspberry Pi blog has published a new article from Adafruit's Ladyada, who lists a few of her recommended accessories for building Raspberry Pi machine learning projects. 'Hi folks, Ladyada here from Adafruit. The Raspberry Pi folks said we could do a guest post on our Adafruit BrainCraft HAT & Voice Bonnet, so here we go!'

Here is a quick shot of how I am powering the Raspberry Pi, the Touch Screen, and the Arduino Nano / Neo Pixels. The striped red USB cable powers the screen, via a 2.4A port on a battery bank, while the black USB cable powers the Raspberry Pi 3 from a 2.4A port on a second battery bank. This Slot Machine is created with Java. The program run on Raspberry Pi overclocked at 1GHz with 512MB RAM. The cabinet is made in plywood. All buttons, rela.

'The BrainCraft HAT has a 240×240 TFT IPS display for inference output, slots for camera connector cable for imaging projects, a 5-way joystick, a button for UI input, left and right microphones, stereo headphone out, stereo 1W speaker out, three RGB DotStar LEDs, two 3-pin STEMMA connectors on PWM pins so they can drive NeoPixels or servos, and Grove/STEMMA/Qwiic I2C port.'

'The Adafruit Voice Bonnet for Raspberry Pi: two speakers plus two mics. Your Raspberry Pi computer is like an electronic brain — and with the Adafruit Voice Bonnet you can give it a mouth and ears as well! Featuring two microphones and two 1Watt speaker outputs using a high-quality I2S codec, this Raspberry Pi add-on will work with any Raspberry Pi with a 2×20 GPIO header, from Raspberry Pi Zero up to Raspberry Pi 4 and beyond.'

Raspberry Pi enthusiasts interested in learning more about using the new Raspberry Pi Compute module with external graphics cards may be interested in a new video created by Raspberry Pi aficionado Jeff Geerling, who explains a little more about his experimentation below. A couple of graphics cards used in the project include the Zotac Nvidia GeForce GT 710 and VisionTek AMD Radeon 5450.

'After I learned the Raspberry Pi Compute Module 4 IO Board comes with a PCIe slot, I know the first thing I thought about testing was a graphics card. The Mali GPU inside the Pi 4 is decent on its own, but what if you could use external video cards, for mining, for rendering, or for CUDA or other GPU-accelerated computing purposes?'
