The BCPB2 - 3S 18650 Lithium battery charger and balance protection board is a charging and protection module for 3 pcs Lithium batteries pack. It is highly integrated and can be used as portable power bank. With MPPT charging ICs equipped, this board works as charger and supports 15-24V power supply for charging. Four indicators are equipped as battery status reminder. The Lithium battery charger and balance protection board works constantly to monitor each cell’s voltage, the current of charge or discharge, and the temperature of the environment to provide overcharge, over-discharge, overcurrent and over-temperature protections, etc.
When fully charged, it can provides 12.6V. With 3.6 x 2.7 inches size, the BCPB2 can be connected with JAB series through L-type Aluminum Bracket for portable Bluetooth speaker.
Larger Capacity and Longer Serviceable Time – BCPC3/4
As the new comer of BCPB (Battery Charging and Protection Board) series, BCPB3/4 inherits the high efficiency and high reliability of BCPB2, offering more battery holders and larger capacity. BCPB3/4 is designed for 5pieces 18650/26650 Lithium Batteries in series and can be used as a power bank for Routers, Raspberry Pi, High power portable speakers and Mobile phones, which is widely used in Home DIY applications to save your precious time from the connection of electric wires. Supporting wide range of charging input voltage and hybrid charging sources is one of the highlights of BCPB3/4. Any 5-24V 2A adapters can be used to charge the batteries with BCPB3/4.
With MPPT charging circuit equipped, this board works as MPPT solar charge controller and supports up to 35W charging ability. Besides that, the balance and protection circuit constantly to monitor each cell’s voltage, the current of charging or discharging, and the temperature of the environment to provide overcharge, over-discharge, output over-current, short circuit, charge over-current and over-temperature protections, etc.
Ground noise commonly exists in analog audio system, which gives listeners bad hearing experience. Nowadays, system-on-chip is used in industrial applications such as game machine, vending machine and other self-service equipment, making it essential that there is digital input interface on the audio amplifier.
On basis of the TAS5756 from Texas Instruments, Sure Electronics launched new amplifier board – AA-AB32255, a digital input high performance Class D audio amplifier with integrated audio processor. It provides 20Watts stereo, making it suitable for PC audio, Sound bars, Active speaker, DIY applications such as Raspberry pi.
AA-AB32255 supports I2S digital input and supports high resolution playback up to 192kHz/24bit so customers can enjoy music same as originally recorded. Its advanced design offers low noise, high SNR and low THD+N as 0.08%, delivering premium audio quality to listeners.
Besides, this board also provides 3-wire audio digital interface (no MCLK required), supporting Raspberry Pi, offering a swift and convenient audio solution for DIYers. It can also work as a high performance stereo audio DAC and supports direct analog output without amplification.
