Microduino-BT is a BLE serial transparent transmission module based on CC2541 chip. It is custom-made for U-shaped 27PIN standard interface of Microduino. Dimensions (mm): 30,5x25,5x7,5.
Features
Adopt Microduino UPIN27 standard interface, working by stacking with other Microduino modules;
Adopt TI CC2541 chip with low consumption;
Support iBecons mode;
Multiple ways to restore factory settings;
Use “AT+ RENEW\r\n” instruction to restore;
Test pin DEF to GND and then power on the module. The LED light blinks after LED1 keeps on for three seconds and meantime, loose DEF and factory reset succeeds, you can see the LED light blinks every one second.
Capable of data power-off preservation function;
Support AT instruction and flexible to change serial baud rate, device name, code matching as well as other parameters according to various needs;
Small, cheap, stackable and open source;
Open source hardware circuit design and Arduino compatible programming development environment;
Uniform Microduino interface standard and rich external modules, flexible to connect with other Microduino modules and sensors;
2.54 pin pitch interface makes it easy to be integrated to pegboard.
