Displays, Shields and IoT - Modules for Microcontrollers
By the term modules we mean all the components that really round off a project and raise it to a new level. Our portfolio ranges from Shields which are connected to a Microcontroller and thus enable an interface to the Ethernet, for example, to OLED or LCDs to light emitting diodes in all shapes and colors.
The most popular of these is probably the "Internet of Things". The modules from the IoT have revolutionized microelectronics and have become an indispensable part of today's everyday life.
An overview of the most popular modules for microcontrollers
In recent years, we have received positive feedback on many modules. Of course, we don't want to deprive you of products that have received particularly frequent mention. Among them we count:
| Loudspeaker (passive buzzer) / piezo speaker | Easy to control loudspeaker for generating (admittedly unusual) sounds. |
| I2C LCD module | Standard 1602 LCD with blue backlight and I2C interface. This simplifies the cabling enormously, because only 4 instead of 16 jumpers are needed. |
| Traffic light | The classic for pandemic school lessons. Often used in projects on the topic "CO2 traffic light". |
| mp3 Shield / dfmini | Simple modules for playing .mp3 files. |
| WS2812 LED Rings | LED rings with 8, 12, 24, 36 or 60 WS2812 pixels. The LEDs can be controlled individually and display the RGB color spectrum. |
| ESP8266 | Low cost ESP8266 module with processor chip that can communicate with other devices within the WLAN. |
| ISD1820 Voice Recorder | Simple module for playback recording of short voice messages. |
| SD memory card module | Module for storing data on an SD card. The module is available for both SD and microSD cards. |
| HC-05/06 | Module for wireless communication with mobile devices. The HC-05 / HC-06 modules can be used as master or slave. |
