In/Out Shield for your Arduino, Velleman.

Stem Shield for your Arduino, the Velleman.

ITDB031 is a serial port BLE Module. It is based on TI's CC2541 BLE chip. With it, you can transfer data wirelessly and do remote control. It supports central and peripheral modes. And it supports remote control for the other side that is connected. You can also support custom commands when you combine it with other devices. BLE Bee is compatible with XBee. You can simply connect it to XBee.

Note: The serial interface is 3.3V, not the typical 5V, as with many Arduino boards.

The VMA214/RFM69HC Transceiver Module operates over a wide frequency range, including license exempt ISM (Industry Scientific and Medical) frequency bands 315, 433, 868 and 915MHz. All major RF communication parameters are programmable and most can be configured dynamically.

Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface! Connect the Module of Tuya IoT Interface to your Arduino using the 4 included male wires. Then, connect your Arduino to the Cloud IoT Tuya simply by installing the Tuyav library, which is compatible with ATmega Chipsets (or AVR Platform). This will allow you to connect to the Tuya app via WiFi and allow you to control up to 5 outputs.

The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.
