MQ-8 Hydrogen Gas Sensor Module

The first Raspberry microcontroller with the proprietary RP2040 chip and a dual-core Arm Cortex-M0+, the Foundation's cost-effective yet highly flexible solution. Designed for high performance and with a high degree of digital interfaces. Programming in C/ C++ and MicroPython.

This Seeeduino XIAO is the smallest Arduino compatible plate of the Seeeduino family. It is an Arduino microcontroller, integrated with the SAMD21 microchip. Despite its tiny size, it has enough interfaces for many applications.

The novelty of micro:Bit v2.2 for a more lively introduction to technology for children.

The micro:bit is a pocket computer that can be encoded, customized and controlled for the implementation of digital ideas and games. It measures just 4x5cm and features a fun and easy to use design, so users can create anything from games and animations to slick stories at school, at home or anywhere - all it takes is imagination and creativity. It is fully programmable. This means that each of its LEDs can be individually programmed as can its buttons, inputs and outputs, accelerometer, magnetometer, Bluetooth 5.0 technology, microphone and speaker.

It contains a quick start guide in the same package.

This small 10-DOF sensor module GY-91 is more compact than the GY-80 module.
The module uses a unique MPU-9250 chip combination with built-in 3-axis gyroscope, 3-axis accelerometer, digital compass and BMP280 enhanced barometric pressure sensor.
The MPU-9250, delivered in a 3x3x1mm QFN package, is the smallest 9-axis MotionTracking device in the world and incorporates the latest InvenSense design innovations, allowing dramatically reduced chip size and power consumption, while improving the performance and the cost. Enhancements include low-power accelerometer mode support with only 6.4μA of and provides improved 16-bit compass data resolution (0.15 μT per LSB).

It allows controlling up to 2 direct current motors or a bipolar stepper motor. It also allows to control a unipolar stepper motor configured as bipolar.
Ideal for projects with ARDUINO.
You can use it with PIC, AVR, STM32.
