The Bluno Beetle Shield expands the Beetle's single analog and digital I/O pins to the 3 pin "gravity" interface, giving more power and ground connections and making it easier to attach gravity interface modules. It also includes a convenient external power supply and a 5-8v switch to power the board on and off. To use the shield, the Bluno Beetle is stacked on to the shield's I/O pins and then soldered in place.
This is a Micro SD(TF) module from DFRobot. It is compatible with TF SD card (commonly used in Mobile Phone) which is the most tiny card in the market. SD module has various applications such as data logger, audio, video, graphics. This module will greatly expand the capbility an Arduino can do with their poor limited memory.
This module has SPI interface and 5V power supply which is compatible with Arduino UNO/Mega. The Pinout is fully compatiblw with DFRobot's IO Expansion Shield V7.
Features:
Power supply options: external power supply and USB power (if the use of external power supply chip please send ISP10 near the blue jumper cap removed)
This is an Arduino RF shield that works under 315Mhz. 315M hz is widely applied in areas like vehicle monitoring, remote control, home security system, wireless meter reading, guard monitor system, industrial data acquisition system, wireless tag, identification, non-contact RF card, small wireless data terminals, fire safety systems, wireless remote control system, biological signal acquisition, hydrological/meteorological monitoring, robot control and so on.
This RF Shield is compatible with our remote wireless keynob.
