This is a breakout board for the handy CD74HC4067 16-channel analog / digital multiplexer / demultiplexer. This chip is like a rotary switch - it internally routes the common pin (COM in the diagram, SIG on the board) to one of the 16 channel pins (CHANxx). It works with digital and analog signals (the voltage cannot be higher than VCC), and the...
high-power Stereo Bluetooth Audio module.Dual channels audio signal output.Built-in amplifier module therefore it can connect to loudspeaker directly.It is ideal for DIY wireless Bluetooth speakers and transponders. It can work with APP Sinilink which can display can monitor the current voice source and switch Equalizer.
The Arduino Sensor Kit is a joint electronics starter kit from Seeed and Arduino. It integrates 10 commonly used electronics modules on one PCB, so no breadboard, no soldering, and even no wiring are required. The Arduino content team has also prepared a step-by-step tutorial for this kit. All these features make it an ideal Arduino starter kit for Steam...
