U-Geek Robot Expansion Board for Raspberry Pi

Let your robotic dreams come true with the new DC+Stepper Motor HAT. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control, It also adds the capability to control 4 Servos with perfect timing.

Function:

•    4 H-Bridges:provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 5VDC to 12VDC.
•    Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
•    Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
•    Up to 4 Channel 12-bit PWM/Servo(5V)
•    OneInfrared Receiver(GPIO26)
•    Big terminal block connectors to easily hook up wires (18-26AWG) and power
•    Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power
•    Works best with Raspberry Pi model A+, B+, or Pi 2;Read More

Installing the Keyestudio Raspberry PI GPS Plate

This Keyestudio KS0216 Raspberry Pi GPS Plate (shield) features high performance and low power consumption. It utilizes the NEO-6M Module developed by U-blox. The GPS Module is connected through the 2*20 expansion pins of Raspberry Pi. It features a large size ceramic antenna, sending locating information to GPS through the serial port. It can track up to 8 satellites on 50 channels at high speed, and it produces very accurate location data.

Plug the GPS Plate into Raspberry Pi 3. Upload your code to Raspberry Pi 3, and you can find your exact location within a few meters. It also provides you with very accurate time! It can be used in car navigation, personal positioning, fleet management, navigation and so on.Read More

Raspberry Pi weather station using the Sense HAT

Today, we are going to  set up a Raspberry Pi weather station that can be accessed over the internet. For this, we need the Sense HAT, a Raspberry Pi add-on board that was made especially for the Astro Pi mission. The Astro Pi mission sent two Raspberry Pis (each equipped with a Sense HAT and a few other improvements) to the International Space Station, where they joined British astronaut Tim Peake and helped record information about environmental conditions up there in the space ship.Read More

24-bit, 192KHz Audio for the Raspberry Pi Zero

The pHAT provides a super affordable high-quality DAC for your Raspberry Pi. It pumps out 24-bits at 192KHz from the Raspberry Pi’s I2S interface on its 2×20 pin GPIO header.

Use pHAT DAC to build a tiny, lush-sounding streaming music device, or use it with Scroll pHAT to make a beautiful spectrum analyser!

Features

  • 24-bit audio at 192KHz
  • Line out stereo jack
