Do you have an old I2C board lying around that would be perfect only if it had easyC connectors? With the easyC adapter and a little bit of soldering, you can give it new life. It will be able to connect easily to newer boards with easyC cables.

The adapter has two easyC connection ports and four plated through-holes: SCL, SDA, 3.3V, and GND. It comes with pins that need to be soldered to the board.

Product usage tips:

Connecting easyC devices to the adapter is the same as to any other easyC device. Choose an easyC cable and connect it to the adapter. That’s it.

To ensure the longevity of the adapter, avoid working with it in wet environments. Device operates at the 3.3V voltage level so higher voltages can burn it.

Obstacle sensor, based on TCRT5000, uses infrared diode and photo-receiver to detect obstacle in front of it – emitted light just reflects back to the sensor. Onboard, you’ll find voltage comparator, so just by adjusting the potentiometer, the board gives digital output. There’s LED DO onboard to show the current digital output status. There’s analog output as well, in case you need it. Sensor works particularly well for line-following purposes on small robots.

The HX711 is a highly versatile load cell amplifier that is widely used in various applications requiring precise weight measurements. This version of the breakout comes with a Qwiic connector and a pre-programmed Attiny404 microcontroller. It is designed to convert analog signals into digital values and have them easily available over Qwiic/Stemma QT/easyC, making it ideal for integration with microcontrollers and other digital systems. An Arduino and MicroPython library to communicate with the board is also provided.

This load cell amplifier employs a 24-bit analog-to-digital converter (ADC) to ensure high-resolution and accurate readings. It supports differential input signals and offers two differential input channels, allowing the connection of up to two load cells simultaneously. This feature enables the measurement of both single- and multi-load cell systems, expanding its application range.

The HX711 incorporates an integrated voltage regulator, which provides a stable supply voltage for the load cells and ensures accurate and reliable measurements this Qwiic version only requires a Qwiic cable for operation – send power and I2C data over one convenient connector! You can use the other connector to continue daisy chaining other Qwiic sensors. It also comes with switches for selecting the I2C address.

The HX711 breakout allows you to easily read the weight value from a load-cell sensor (mass sensor). This small ADC is of great precision and is capable of measuring very small changes in the load-cell resistance, whose signals are amplified with the built-in amplifier. Subsequently, this same information is digitally transmitted to a microcontroller that simply converts the numbers obtained into the actual weight. That’s why this breakout is very useful for projects with scales or presence sensors, either for individuals or industry.

Breakout supports the connection of load cells that are made by the Wheatstone Bridge technique, like most of the load cells. They usually have four wires, two for power supply (E + and E, most often red and black), and two for signal (A + and A-, most commonly white and green wire). The pins for these wires are also indicated on the PCB and it is easy to connect.

The TCRT5000 is an infrared (IR) reflective sensor module that is commonly used for proximity sensing and line-following applications. It consists of an infrared emitter and a phototransistor placed side by side in a compact package. The emitter emits infrared light, which gets reflected off nearby objects, and the phototransistor detects the intensity of the reflected light.

This sensor module is widely used in robotics and automation projects. It can be used to detect the presence or absence of objects by measuring the intensity of reflected infrared light. It is also commonly employed in line-following robots where it can detect and follow lines marked with contrasting colors.

The TCRT5000 operates on a supply voltage typically ranging from 3.3V to 5V. The breakout board provides digital and analog information through the easyC system. Sensor readings are obtained through easyC.
