Single Supply Logic Level Converter Hookup Guide
The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.
AVR-Based Serial Enabled LCDs Hookup Guide
The AVR-based Serial Enabled LCDs are a simple and cost effective solution for including a Liquid Crystal Displays (LCDs) into your project. These screens are based on the HD44780 controller, and include an AVR ATMega328p with an Arduino compatible bootloader. They accept control commands via Serial, I2C and SPI. In this tutorial, we will show examples of a simple setup and go through each communication option.
Using the A111 Pulsed Radar Sensor with a Raspberry Pi
Learn how to download, build, and use the Acconeer A111 SDK with a Raspberry Pi! The tiny A111 pulsed coherent radar (PCR) adds high-precision, cutting-edge distance measurement for speed-, material-, motion-,or gesture-sensing projects! We’re not talking about simple ultrasonic, or even infrared, sensors here, but 60GHz radar!
Pi AVR Programmer HAT Hookup Guide
In this tutorial, we will use a Raspberry Pi 3 and the Pi AVR Programmer HAT to program an ATMega328P target. We are going to first program the Arduino bootloader over SPI, and then upload an Arduino sketch over a USB serial COM port.
