Hey Seeekers!

It’s newproductsTuesday! Today we are excited to release two different kinds of shields for Raspberry Pi. They are the 2-Channel CAN-BUS (FD) Shield for Raspberry Pi and the 3D Gesture & Tracking Shield for Raspberry Pi (MGC3130).

2-Channel CAN-BUS (FD) Shield for Raspberry Pi

3D Gesture & Tracking Shield for Raspberry Pi (MGC3130)

We have had the CAN-BUS Shield V2 on our bazaar for quite some time and many of our customers liked it very much to use in their CAN based applications. This shield is an add-on to the Arduino UNO boards and Seeeduino boards to enable all your CAN projects.

However, what if you wanted to build a more powerful CAN based project using a Raspberry Pi? Well…. We, at Seeed Studio, decided to develop a CAN-BUS Shield for Raspberry Pi to enable all your CAN bus projects through a Raspberry Pi. Today we are happy to bring you the all-new 2-Channel CAN-BUS (FD) Shield for Raspberry Pi.

2-Channel CAN-BUS (FD) Shield for Raspberry Pi

This shield is a two-channel CAN BUS hat for Raspberry Pi, which supports the CAN FD protocol and supports transmission speeds up to 8 Mbps.

This is unique when compared with our previous shield because it supports CAN FD! CAN FD (CAN with Flexible Data-Rate) protocol is an upgraded version of the traditional CAN BUS that increases the CAN max transmission rate from 1M to 8M. At the same time, CAN FD improves real-time performance and extends user data frames.

The Seeed 2-Channel CAN-BUS(FD) Shield for Raspberry Pi is based on MCP2517 CAN FD Controller and MCP2557 CAN FD Transceiver, and it communicates with Raspberry Pi via the high-speed SPI interface. You can power this shield with Raspberry Pi via the 40 Pin Header or you can use the 12 ~ 24V DC screw terminal to supply the power for the whole system. High-quality Panasonic capacitors and TI power chips, reasonable circuit design to build a stable power management system, which provides stable 3.3V and 5V power supply for all parts of the system, to ensure the stability of communication.

We know that the devices at both ends of the CAN BUS need to add a 120Ω terminating resistor to avoid reflection. With the help of an onboard 120Ω resistor and it enables switch, you can easily choose whether you need to connect a 120Ω resistor. Besides we provide two Grove I2C connectors for you, in case you need to work with more Grove modules.

3D Gesture & Tracking Shield for Raspberry Pi (MGC3130)

This shield is based on the Microchip MGC3130 chip, which enables the Raspberry Pi with 3D gesture recognition and motion tracking function. It can capture x y z position information and can also do proximity sensing and touch sensing: supports tap, and double click.

As shown in the figure below, the recognition area is divided into two parts: the strip area is distributed around and a central panel.

The strip areas can sense the orientation change, including the North, South, West, and East. The central area can sense touch, tap, double click, and gestures in the air above. That’s why we call it 3D Gesture & Tracking Shield, you don’t even need to touch the central area directly, just wave your hand above the central area, and this shield can sense your movements.

Thanks to the Microchip’s patented GestIC® technology, this shield utilizes electrical near-field sensing to detect movements. The shield generates a magnetic field above the central panel. When the hand approaches, it will interfere with the magnetic field, and the magnetic field receiver below the shield can detect the change.

This is an amazing module. You can perform gestures using this to control lights, TV, speakers… Just unleash your imagination and create more magical projects.
