Screw Shield for Arduino

The CAN-BUS Arduino Shield v2.0 can be stacked on an Arduino UNO, Arduino Leonardo or Arduino MEGA board. The shield integrates an MCP2515 CAN-BUS chip on the shield and has a CAN-BUS transceiver function. With an on-board DB9 and CAN-BUS connector you can choose a suitable port according to your host device. There is also an integrated MicroSD socket for data storage. DFR0370

Extension module (shield) with a signal generator for Arduino Pro Mini. It can trigger a sine, square or triangle waveform up to 3MHz. SparkFun BOB-11420

Voltage divider module for measuring quantities in the 0V to 25V range.

Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265

The X-NUCLEO-53L0A1 expansion board features the VL53L0X ranging and gesture detection sensor, based on ST’s FlightSense™, Time-of-Flight technology. It is an evaluation board that provides an introduction to the ranging and gesture detection capabilities of the VL53L0X module

Wixel Shield for Arduino

The Bees shield is compatible with Arduino boards such as UNO R3 and Leonardo it has a large prototyping shield giving you plenty of space to experiment and add extra components to your project. Thanks to its uniform interface, there are a huge number of devices compatible with the xBee socket: xBee, WiFi xBee, Bluetooth Bee, zigBee, etc. DFR0210
