In this guide, I'll explain the 3 main lens options for a Raspberry Pi HQ Camera and the advantages and disadvantages associated with each.

This project uses a Feather M4 and Trinamic's TMC-2226 stepper motor driver to enable you to take long exposures of the night sky with just about any camera. This project was designed to be much cheaper commercial equatorial mount trackers and to be easily (and cheaply) modified and customized, a feature many other trackers lack.

This project uses a PyPortal to make a customizable remote which works over WiFi to control a Roku media player. It uses the Roku External Control Protocol and takes advantage of the PyPortal's touchscreen for a very easy to use input method.

This project makes use of two of the many features available on Circuit Playgrounds; the accelerometer and the NeoPixels. It uses the accelerometer to sense if the bike is braking and then uses the NeoPixels to indicate that the bike is slowing down.

The LIS331HH and H3LIS331 3-axis accelerometers from ST provide the user with high-g acceleration sensing like never before seen from an ST LIS3xx accelerometer. The more humble of the two, the LIS331HH can measure up to a range of +/- 24g on each of its three axes. The flashier H3LIS331 doesn't play around and will measure as much as +/- 400g. That's no typo!

This guide shows how to use the ICM20649 from InvenSense is a Wide-Range 6-DoF accelerometer and Gyro, capable of measuring up to ±30g and ±4000 dps! Overview of features is followed by an explanation of the pinout, and then showing the user how to wire up and use the sensor with Arduino, CircuitPython and Python.

Pyloton is the CircuitPython bike computer made with the Adafruit CLUE board. Pyloton has Bluetooth LE heart rate, speed, and cadence sensors as well as Apple Music Service song info all combined into one small device with a sharp display and a 3D printed handlebar mount.

With FT232H support added to Blinka, you can now use CircuitPython libraries to talk to the wide range of I2C and SPI based sensors and breakout boards - from any Windows/Mac/Linux PC with a USB port.

These displays use 4-wire SPI to communicate and have their own pixel-addressable frame buffer, and can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! They have 240x240 16-bit full color pixels and is an IPS display, so the color looks great up to 80 degrees off axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well. There is also a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card.

CircuitPython is the best new way to code microcontrollers. But what if you want to run that same code on a more POWERFUL computer like a Google Coral Edge TPU (or really any Linux SBC?) Well now you can - take advantage of the wide collection of drivers and example code we have for CircuitPython and now you can run it right on your Coral!

This guide covers all the steps to releasing a CircuitPython library for the world to use. We'll cover GitHub, ReadTheDocs and Travis.

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple

Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or perhaps communicate with a Phone (choose Bluetooth Low Energy!) but what if you want to send data very far?

Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and SPI!
