Overview
The DFRobot Solar Power Manager series are designed for IoT projects and renewable energy projects, providing safe and high-efficiency embedded solar power management modules for makers and application engineers.
This medium-power high-efficiency solar power management module allows you to charge a 12V lead-acid battery with a maximum of 4A using a standard 18V solar panel.
Solar Power Manager For 12V Lead-Acid Battery is a medium-power high-efficiency solar power management module, which is able to charge a 12V lead-acid battery with a maximum of 4A using a standard 18V solar panel. It is suitable for applications within 100W, such as 12V lighting equipment, security monitoring, small robots, pumps or environmental monitoring stations.
It features as MPPT(Maximum Power Point Tracking) function, maximizing the output power of solar panels under various sunlight. Compared with common PWM solar controllers, it can improve charging performance by 10%-30%. Benefited from its small size and light weight, it is easier to embed it in your projects.
The module provides dual high-power outputs 5V 5A (OUT1) and 12V 8A (OUT2) and dual USB outputs 5V 2.5A (USB1/USB2). Except USB1, all outputs can be turned ON/OFF by I/O pins of most controllers (3.3V/5V compatible).
This feature helps to dynamically power loads and reduce power consumption. Various protection functions are also employed to ensure the safety and stability of the solar systems.

Easy data logging with grove sensors using the MKR Connector Carrier and MKR boards

Say hello to the newest member of the Arduino family! The MKRZero--now available on our stores at the price of $21.90/€20.90 (+ tax)--shrinks the functionality of the Arduino Zero down into an Arduino MKR1000 form factor, making it a great educational tool for learning about 32-bit application development. Like the Zero, the latest board is based on a Microchip SAM D21 ARM Cortex®-M0+ MCU. An integrated SD connector with dedicated SPI interfaces (SPI1) allows you to play with files without any extra hardware, while an analog converter enables you to monitor its battery voltage. The MKRZero’s features in a nutshell: small form factor number crunching capability low power consumption integrated battery management USB host integrated SD management programmable SPI, I2C and UART Interested? You can explore the MKRZero in more detail, including its technical documentation, via the links below: Product Page Getting Started Guide Tutorials on Project Hub Make a ScheduledDataLogging Create a I2S synth generator (theremin) Read battery voltage Make it rain On the software side: If you use the Arduino IDE, you will need to add the new Intel SAMD Core, selecting Tools menu, then Boards, and last Boards Manager on the Arduino Software (IDE). If you use Arduino Web Editor, everything is already updated! Watch out music makers, we’ve got some news for you! We have released two libraries for your enjoyment: Arduino Sound library - a simple way to play and analyze audio data using Arduino on SAM D21-based boards. I2S library - to use the I2S protocol on SAMD21-based boards. For those who don’t know, I2S (Inter-IC Sound) is an electrical serial bus interface standard for connecting digital audio devices.
