Use 5050 full color super bright LED

With current limiting resistor to prevent burning out the LED

Can be accessed by a variety of micro-controllers

Can be directly inserted in the Arduino motherboard

The power meter, the module does not work.

Each type of bluetooth module can be installed commonly, such as HC05/06/07 / BC04 or other compatible bluetooth module per definition.

With clear key, it can be support pin of the module (e.g., host HC05/06/07)

Set EN can make pin, suspended or high levels, the normal work of the module; Closes as earthing module power (closed current < 20ua) reduce power consumption.

Note: connection BC04 default for hardware settings and from the pattern, if you need to modify for the software settings should be from 3.3V to PIO4 fly line.

This Coin Cell Battery Holder has a small slide installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the slide switch board, so it’s not easy to accidentally turn off or on.

Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (2 positive and 2 negative) for sewing into your project.

The product is composed of optical fingerprint sensor, high speed DSP processor, high performance fingerprint matching algorithm, super large capacity FLASH chip and other hardware and software components. The fingerprint module has the functions of fingerprint collection, fingerprint registration, fingerprint matching and fingerprint search.
