Waveshare: High quality modules for your Raspberry Pi

Waveshare is a reliable specialist when it comes to displays, cameras and other modules for your Raspberry Pi. With the products of the innovative electronics expert, you can turn your computer into a true all-round device.

Waveshare provides an optimal view

You are looking for the ideal display module for your Raspberry Pi? At Berrybase you will find a wide range of products from Waveshare. Each display and all associated modules have been designed with the utmost precision and meet the highest demands - no matter what purpose the respective product is supposed to serve.

For example, the Waveshare ePaper HATs offer perfect conditions if you want a high display quality even in strong sunlight. A big advantage of ePaper displays is their extremely low energy consumption. The best example is the 2.13" 250×122 ePaper Display HAT with integrated controller, which is optimally tailored to the Raspberry Pi 2B, 3B, Zero and Zero W. The communication with this module is done via SPI interface. The ePaper display equipped with the HAT is limited to the colors black and white and reflects light like conventional paper. This is good for the display quality.

If you prefer a display in the three colors red, black and white to complement your Raspberry Pi, the 2.7" 264×176 ePaper Display HAT is recommended. It has the same technical features as the other Waveshare ePaper HATS.

Compact and of brilliant quality: The Waveshare 7 inch Display

The Waveshare 7 inch display, on the other hand, scores not only with its compact design, but also with a 1024x600 hardware resolution and capacitive touch control. On all devices with Raspberry Pi OS, the 7 inch LCD even works driver-free. The integrated 3.5mm jack enables sound output, while the image is produced via an HDMI connection. The impeccable quality manifests itself in a high-quality glass surface with a 6H hardness level.

At Berrybase, you can get the display including a robust case on request - so that it is optimally protected against external influences. Besides the Waveshare 7 inch display, the electronics specialist also has many other screens in different sizes available.

Waveshare Game HAT: Turning your Raspberry Pi into a game console

One of the top sellers at Berrybase is the Waveshare Game HAT for the Raspberry Pi. The controller transforms your computer into a mobile game console. The 3.5" IPS display convinces with a 480×320 resolution and ensures smooth image playback and thus unlimited gaming fun. The sound is reproduced via on-board speakers or optionally via the 3.5 mm jack socket. The battery of the Game HAT is charged via the integrated charging circuit. The module is compatible with the Raspberry Pi models A+, B+, 2B, 3B and 3B+. For other versions the connection via HDMI cable is possible.

If you want to turn your Raspberry Pi into a mobile retro console, we recommend the GamePi43 with a 4.3-inch IPS display, which is suitable for the Raspberry Pi models B+, 2B, 3B and 3B+, or the especially compact GamePi20. The latter features a 2.0-inch IPS display and is compatible with the Raspberry Pi Zero 1.3, Zero W as well as the Zero WH.

Practical accessories for every purpose

By the way: Waveshare's product range is also peppered with useful accessories for your Raspberry Pi. The Li-Ion battery HAT for example provides a mobile power supply for your computer. The 8 channel DIN rail relay module from Waveshare allows you to use your Raspberry Pi as a control module for tech projects in the home, for example to centrally control the home lighting or shutters. And with the Ethernet / USB HUB HAT, Waveshare has designed a module that extends the USB capability of your Raspberry Pi and provides an RJ45 Ethernet port. The latter offers an enormous added value when a stable wired Ethernet connection is required.
